Video still great in 2023. Just swap out my map sensor and diaphragm. Thanks for the help. 2013 VW Golf 2.5L with 104K miles. Never selling this car. It’s awesome.
330k on mine and still strong. 👍
Gotta check out part 2 because there's 2 pressure sensors & a few other things that can cause that code.
@@wandameadows5736 will check it asap. Thanks for the heads up. Cause I’m keeping this baby to a million miles lol.
OMG! Thanks for this video! I watched this before cleaning my MAP sensor! I changed the evap purge valve, cleaned the MAP sensor and changed that diaphragm at 1:56! Oh and cleaned the throttle body. 2012 VW Passat 2.5L 5cyl 103,000 miles. Drives like entirely different vehicle! I am absolutely stunned! I would have never known to change that diaphragm! Mine had a gap/hole in it and was leaking! These fixes are not bad at all! My Passat is one hell of a machine being slightly over 100k miles! VW/German engineered vehicles are so fascinating! Love VW! My 2013 Tiguan 2.0 TSI 30,000 miles is great too! No problems with that vehicle yet. ✌🏻❤️👍🏻
I'm getting same code in my 2011 Jetta 2.5L. I thought I should replace the sensor, but sounds like I should clean it and change the diaphragm before replacing sensor correct?
@@davisgrier5162 Yes I would recommend doing both the sensor and the diaphragm. I replaced just my sensor and had my code come back. Were you able to resolve your issue?
My 13 Passat just had this pop up at 146,000 I'll fix it when I get done with truck driver orientation 🤙🏿
I had the exact same code p0106 and broken diaphram in the pvc. Expertly and succinctly explained and problem handled. Thank you. Got the same Dorman part at O'riellys.
Thanks for the great video, the only one I found that identified the root cause. My 2010 Jetta 2.5L was throwing a random check engine light, then finally started running in limp mode, not going over 3000rpm. G71 and G61 error codes. The parts are cheap enough so I replaced both and back to normal. I hope it also cuts down on the oil consumption too.
Super super useful my man. My 2.5 golf is in the same premise rn. Gona check tomorrow and try to clean as much oil as I can if there is any. Defiantly subbed 👍👍
Here is a tip for you good people dealing with this p0106 issue. Check your intake manifold bolts, they may be loose. A loose intake manifold can contribute to a code p0106. Upon doing this, clean the inside of the intake manifold, clean out your throttle body, clean out your hoses & check your intake manifold bolts.
Throttle body - torx 30
Intake manifold bolts - either a 6mm hex or a torx 40 (8 inch or longer "Bit" works best to reach)
Clean with throttle/intake cleaner
For map sensor, clean with map sensor cleaner and let it dry for at least 15 minutes. Map Sensor cleaner can be bought at walmart/autozone/oreily
Clear out your p0106 with an obII reader or disconnect & reconnect your battery.
Good luck and hope it helps you.
How do the intake bolts go lose if no one worked on the intake? Are these bolts become lose by time with the engine vibrations or expansion and contraction?
@@surefire07 maybe the valve cover gasket?
Thank you very much for making this video. it was really helpful.
The Man The Myth The Legend this was my problem 09 jetta subscribed for life :)
I just got a 09 jetta it makes a weird sound kinda like an old caravan
I got the car for 2000 cash
I found a picture of a map sensor with the price of roughly 100
Any advice???
Thank you very much for the video. This helped me diagnose this issue quickly.
awesome job doing the repair, very clear explanation, thank you very much for this video
Indeed he did, well explained, no bullshit in between like others do!
Super helpful video. Two thumbs up dude!
Thanks a Lot Amigo For This Really Helpful Video Tutorial !! May God Bless You ...
Thanks for making this video it really helped me out
i have a 2012 beetle but basically had the same engine set up. but this helped me :D changed my map sensor today, found that the diaphragm was blown and had tears and there was oil all over my sensor. so i changed that. I wouldnt have known that part would have been a culprit to my sensors death. also found a mouse nest in my air box :/ but my car is running good now! :D thanks for the video advice!
Thanks for the video. Nicely explained!
Thanks for all the info! Now i am totally prepared! Great video!
Question - I replaced the Map sensor and that round cap part but I’m still getting code P0106.
Please help need advice. Thank you 🙏
Once you replace the pvc how long should it take the excess oil to clear out from where the map sensor is?
Hey I have code P0491 secondary Air Injection System Insufficient Flow Bank 1. I removed throttle body and my intake manifold is full of oil same as yours, do you think I need to replace same part as you did? Thanks
Thank you, neirbord asked me where is was, now he know without me even getting dirty
Dude you are a fucking godsend.
Cheers from a lifetime owner of VW Jettas.
🍻
Great video!
I knew something was going wrong the last few months, but obviously didn't know for sure until MIL came on....going to go check it out now!
BTW, I had thought of doing a transmission fluid flush because the shifting of the car has been way off it's driving me nuts....I thought I could have started with that, but now I'm very curious about how car will drive after checking out MAP sensor and PCV Nice video!
Best thing I have done is reset the transmission control... I don't remember exactly how to do that without youtubing but if you get in your car (without turning it on) you'll notice that pressing all the way down the accelerator will click a button. Google after that (because every VW is different) but its something like pressing all the way down on that and clicking the button and then turning the car on (without starting the engine) and holding it for around 30 seconds. And its a reset for the transmission control. Often times resolves awkward transmission shifts.
Did this fix the issue? I would get random pulls thinking it was the trans fluid as well. I just got the check engine light.
@@mauriciopereira7705 Honestly there was nothing wrong with the transmission, it was the MAP sensor getting all oily (which is ridiculous), and my throttle body was extremely dirty/sticky.
I feel like the feeling of a 'bad transmission' was coming from the dirty/sticky throttle body. Then, it so happens to turn out the MAP was oily as well. 😕
Does that help?
replaced PCV diaphragm (tho it wasn't broken) and MAP sensor. Sill getting error code, specially during hot days. I don't know what else to do
Just replaced everything, did the spark plugs while I was in there. Hope this works!!!
To
Great video, thanks
P.S. Great informative video!
What about the p0113 Intake Temperature Sensor? Where in the hell is the thing located? It’s not on the intake of my 2.5 Jetta like so I’m super confused at how to,clear it it. Is the MAP and IAT one sensor now?
Great video! Thanks
What happens when you pull the map sensor comes out clean? Every time this happens and it’s a lot! I always pull it out and it’s clean. I cleaned the throttle body as well. To no avail
Thanx for great video , my 2012 Passat with 69k miles on it have a code PO106 , no issue while driving , dude from auto zone told me I need to bring my car to REAL mechanic who knows VW's , looks like ease fix
Did he end up replacing map censor?
Great video bro...i have a 2010 2.5 jetta...and i have the same code....
Great vid. Thanks🍻
Thank you for the Help
Thanks for posting
Hi Skyhook Studios,
I have a 2012 VW Jetta SE 2.5L and I am having a heck of a time locating the MAFS. My engine layout is identical to the 2011 in the video. The MAFS is not located where you would expect it to be i.e. connected to the air intake attached to the engine cover. Any advice is greatly appreciated.
Thank you.
Best Regards.
Looks like you posted this a while ago so I hope you figured it out already but if you haven't... There is no maf sensor on the 2012 2.5L engine. Only a maP sensor (I capitalized the P on purpose!!!) - Manifold absolute pressure sensor. There is no mass airflow sensor. The MAP senor is like $30 so it's a cheap replacement
Question: I didn't make any attempt to remove the Map sensor and check it due to lack of time, but my PCV diaphragm did have a huge hole in it. I'm wondering if a fuel system cleaner like Red Line will clear out the oil left inside. What do you think?
Fuel system cleaners are not designed to perform that job. They are marketed as a fuel injector and or valve cleaner. The issue is that oil doesn't atomize very well and simply running the car will not get all the oil out. The shape of the plastic intake plenum adds to the chances of oil staying trapped at the bottom, where the MAP sensor resides.
Great video. Going to replace the diaphragm and MAP sensor this weekend. I have a 2012 Passat 2.5. If all goes well, will the code clear itself, or must I track down a scanner and clear the code manually? The check engine light has been coming and going for awhile now, but now seems to consistently stay on (with the P0106 code).
Having the same issue with my 2012 Passat 2.5. Replaced my MAP sensor, cleared the code using a scanner, code came back. Will be replacing the diaphragm and cleaning the MAP sensor to maybe fix the issue. Were you able fix your issue?
@@JoeSmoeDoeLow did you ever resolve the problem?
@@eluna58 yes I solved it. I replaced the map sensor and the diaphragm and then cleared the code using my scanner. I put 15,000 miles on the car and no code has returned.
@@JoeSmoeDoeLow ok, thank I'm going to first try and just change the diaphragm and clean the sensor hopefully that works. Thanks for the reply
For clarification- the reference at the end of the video about the code coming back, was before replacing the PCV diaphragm. Once replaced, code never came back.
I have been driving my Jetta for 3 years with this code appearing about 2 times per month. I deal with it so often that I have a code reader in the passenger seat and I have developed the ability to clear the code while driving! I saw this post at random a few weeks ago. I bought a PCV valve from Rock Auto for a few bucks (less than the cost of the code scanner) and now my problem is solved!!! THANK YOU SOOOOO MUCH!!!!!
You're the man! I just replaced my diaphragm because of this video, Thanks for making this!
Does anyone have a link on where I can purchase this part?
At 4:09 the plastic pipe on my car only has one hole in the side not two like yours... I have a 2.5 passat 5 speed. Is there a reason to this?
Inan Ismailov probably just a different set up for emissions. Regulations change per region not to mention car so it probably something like that.
So theres oil residue all inside there. If you don't get it all cleaned out, will it foul the new sensor? I bought a new MAP and diaphram. Gonna replace both this weekend.
huggyjd Try to get as much as you can. Normal air flow will clear up any thats left.
What's the average shop cost for this repair?
I like those head lights
Can the MAP sensor be taken out without removing the throttle body assembly? I just popped the hood of my 2012 jetta 2.5L and i think i see it below to the throttle body covered behind a hose. I recently got the same P0106 code as well. Good info on the diaphram.
Technically, I would say yes. I think it would be rather difficult though. Removal of the components is neither difficult or damaging (no gaskets needed).
Is it normal for the engine light to come on after doing this repair? I replaced both sensor and PCV valve. Cleared the code and it came back after 4 days. Cleared it again. Will the check engine light eventually stop coming on after awhile? Thanks!
Great video by the way!
I have the same code P0106 on my 2011 Jetta SE. 145,000 Km. I have ordered the diaphragm for my PCV valve. Are there other problems that might be causing this code besides oil on the map sensor from the damaged diaphragm?
An intake leak beyond the mass air flow could cause it. Generally in my experience, the code is more of a product of the air leak caused by the tear in the diaphragm. I'm sure that oil doesn't help the sensor though.
Wow this is such a clutch video, the problem started on the day you posted this! Anyways, you mentioned that this light is persistent, and reappears after a while. What other attempts did you make to fix this problem?
PISTOL PETE the reference to the light being persistant was that, before preforming the fix, it would take a few days to return if I would simply clear the light without doing any work. If you have the code, check the map sensor or intake for oil. If there is any, then you have a pcv torn. Since the fix, the code and tested and passed without issue.
Actually I ended up doing nothing and the code disappeared after a car wash. I wonder what will happen if I try to get a diagnosis test now
PISTOL PETE Thats how mine was at first. The code didn't go away because of the car wash. Like I said in the video, it came and went for me at first. Eventually it stayed on constantly. The code is still in there. 3 key cycles in a row without an issue and the light goes away. The stored code take much longer to clear from the computer.
Could this give a P0300 ?
I had same issue but mine required dealer to reprogram computer. Vw isssued a tsb for mapp sensor due to sensitivity level. Once reprogrammed never had light come on again. If you google vw 2.5 mapp tsb will talk about reprogramming computer and not to replace sensor. Just spent alot of time replacing sensor and cleaning intake finally taking to dealer and that’s how it was fixed. Is a common issue on 2.5 engine
Look up VW TSB 2034012. My CEL came on with this code and they needed to upgrade the ECM software, not replace the MAP sensor. This was covered under the 15 year PZEV warranty.
Hi! I have the same problem and I read about the VW TSB 2034012 but I don't how can I require that upgrade... could you please give a little bit more information about how did you order that upgrade?
I got P0106 code, did what you say on video, drove car for about 100 miles, but code pops up again.
Will the condition be worst if I drive the car with this code for about 2 weeks before fixing it? I experience a little bit of reduction in acceleration power (not too bad though) right after the check engine light turns on. Can it be fixed by following your repair? thanks for the video!
You should never neglect car repair, especially check engine light issues. Try to get it looked at and repaired as soon as possible. Second, there are many reasons why your car might have this specific code. This video shows a repair of the most common cause of this code.
I had changed my valve cover completely with the diaphram. Changed the with a new Bosch sensor and won't go away. Lost as to what to do next.
Here is a tip for you, check your intake manifold bolts, they may be loose. A loose intake manifold can contribute to a code p0106. Upon doing this, vlean inside the intake manifold, clean out your throttle body, clean out your hoses & check your intake manifold bolts.
Throttle body - torx 30
Intake manifold bolts - either a 6mm hex or a torx 40
Clean with throttle/intake cleaner
For map sensor, clean with map sensor cleaner..could be bought at walmart.
Vlear out your p0206 with an obII reader.
Good luck and hope it helps you.
I followed this video and cleaned the oil out. Cleaned the intact out.... eventually REPLACED the sensor and the car is still returning the SAME ERROR regardless of trying to delete the DTC.... Its gotten to the point it caused a check engine light. Temporarily cleared the check engine light but its still returning a P10106 and im getting pissed off. The entire sensor is replaced, the intake is cleaned out... Any advice?
Did you replace the PCV diaphragm?
very nice!
My car is jetta 2010 and every thing looks identical to your car. BUT does this car has 2 MAP sensors? there's another sensor looks exactly like the MAP sensor, it's located under the oil cap and a little bit to the right. I got the same exact problem, but I replaced the other one and the code came back the next day. I didn't check the throttle body or underneath to see if there's another sensor. I'll check on that, Thank you!!
Mohamad sy just one map sensor like in the video.
Are you sure? Then what is the purpose of the other one that is under the oil cap? It's the same exact sensor. I checked my car and it does have the one you replaced at the same location, but didn't get chance to swipe them. I'm confused now!
Mohamad sy The MAP sensor is simply a pressure sensor. Car makers use the same sensors for multiple things. The MAP sensor is where I described in the video. Any thing else is probably just a pressure sensor for another system. make sure to watch the "whole" video. I did NOT replace the MAP sensor. I replaced the PCV valve and CLEANED the sensor.
Alright thank you! I will do everything you did and tell you how it went. I searched a lot but no one has any post or video about where the sensor is located so I got the wrong one. Thank you again for the videos !
how did it go?
Even with a new valve cover/pcv that I did myself...$90..And the new sensor as well as cleaned out the hose from the pcv valve the code still comes back and everything is dry. It's a permanent code with how they made that law I believe in 09 for emission inspection purposes..I'm finding that getting rid of permanent codes is the hard part even though the car is fixed. I had 4 other permanent codes as well when I picked up the car which was in great condition but needed some help. It had a broken chain tensionsor which set off many sensor permanent codes. I fixed all that myself as well as replacing both chains and guides and tensionsers...Only one permanent code so far has taken care of itself although the car now runs as new again...grrr...its not easy to get rid of them when they go that far. My car only had 80,000 miles on it when I bought it and as I figured just poor maintenance. Wrong oil, not having oil changes on time etc. Luckily after cleaning under the valve cover by hand for a couple of days with the light later of old oil and some gunk, then flushing the engine with the Liqui moly engine flush everything is good again. Compression is good, no exhaust smoke and power is good. Did the DSG filter and fluid as well and of course new ignition coils and plugs to finish the complete tune up. I got the car at a very good price as expected with the issues it had and had it on the road running great in a couple of weeks after work project...Great car,,but those permanent codes can be a pain to get rid of. Trying other methods I've researched as well to clear them too...Wish me luck...really like the car. The money we save being able to do our own work is unbelievable with what VW wants to charge for simple fixes.
I feel your pain. Having the correct scanner equipment is a must as the years go by. I understand that it is cost prohibitive for most to have supportive scanner hardware let alone the software to accompany it. But it's getting to be impossible to perform work on the vehicles otherwise.
I’m dealing with the code coming back after all the repairs have been made same as you. The car runs great but I do notice the car doesn’t do the cold start with warm up cycle anymore. It just goes straight to normal idle. I’m now getting a too rich at idle error and not sure what to check for next along with the P0106 code that keeps reappearing.
@@Suprasian ricksfreeautorepairadvice.com/vw-p0106/
I also replaced all spark plugs with E3 s plugs. Car drives so much better- but I’m getting a new code P2178 Fuel too rich off idle. VW Jetta mk5 2.5L
I had the same fault code plus multiple codes for misfires cylinders, the engine was idling really rough, shaking, and vibrating badly. I also noticed a hissing noise, which I suspected was an exhaust gasket leak coming from the left side of the engine. I was thinking for a moment, what a coincidence?
Anyway, I replaced the PCV diaphragm which was burst wide open, clean the MAP sensor in the intake as it was full of oil. No luck. Then, while I was running the engine, I increased the rpm to approx 4000 and I heard a pop. Stop the engine, had a look, and surprise, one of the plugs installed on the left side wall of the engine (by the cooling fluid reservoir) was missing. Oil was spitting out from the hole. They are called actually camshaft caps. That was the popping noise. The hissing noise, I assume it was actually from that plastic plug, and probably when I increased the rpm, the pressure just popped it right out. Waiting for the part now. I ordered two as I will preventively replace the other one too. I Will update soon.
Hey Eugene, what was the verdict on your problem with your vehicle? I’m having the same problem…
@@Hudsonnblackk On the engine block on the left hand side (by the cooling fluid reservoire, there are two plastic plugs. I'm not sure what is the purpose but I think due to the blowned PCV diaphragm, it create a vacuum inside the engine and sucked in one of those plugs. Anyway, I removed the crankcase cover and I found the plug inside, resting by one of the valve lifters. I could re-install it but I bought new aftermarket ones and installed it. I did apply some RTV sealant on it, just in case. So, the main culpit was the PCV diaphragm, second, I found oil in the throttle intake, (there is a sensor there too), removed the throttle body, cleaned it up, and third issue was the plastic plug on the engine left-hand side. The plug was very dificult to troubleshoot as the engine was running soo rough , I thought there was piston broken or worst. Since then, she runs perfect. All these were induced by the PCV diaphragm which I never replaced it in more than 10 years. Some people are replacing them every few years. They are cheap and easy to replace.
I replaced the map sensor and pcv and the code came back after 10 miles. Should I have cleaned the throttle body too?
Did you get this issue resolved?
Van Coll no the code keeps coming back every few days after I clear it
Would this give an Engine AND a EPC light? On my 2008 Jetta 2.5, VW told me I had a P3078, P0322 and P0106 (nothing printed out, just handwritten by mechanic). I cleaned out the TB and did see some oil, but overall it was very clean. I was told Speed and MAP sensors. But after this video, the diaphragm would be an inexpensive fix. Great video. Thank you!
The 3078 and the 106 could very much be related. They both can be triggered by intake air leaks possibly caused by a ripped pcv diaphragm. As some other posts have suggested, VW has a campaign out for the P0106 code which involves reprogramming the ECU. I don't think that's gonna fix your issues since you have more then just the 106 code. Secondly, the 322 code is for the engine speed sensor and is most likely intermittently faulting. I say that because the engine speed sensor (aka crank sensor) will prevent the vehicle from starting if bad and will stop the engine immediately if it goes bad while running.
Replaced the MAP sensor and diaphragm, but no luck. The chamber covered by the diaphragm had a thin brown film on it that I cleaned out. The Speed sensor is next. I think this will do it.
My 2010 Jetta 2.5 throws to map code and when it does it shifts hard I clear the code AS shifts easy anybody have that issue
i have the same problem did you figure out what's causing that?
@@_DaRobot same problem
I really thought I was the only one haha… was it just the map sensor?
@@_DaRobotdid you figure it out?
How do you find and then step by step pool out the map sensor to clean it?
Serenity ❤️
Changed the pcv valve also the sensor and still runs the check engine and the p0106 code ,
Any recommendations?
There's 2 sensors & several other things that can cause that code. VW made an upgraded Secondary Air Injection Pipe for VW/AUDI part# 07K198125. I have a 2012 VW Jetta 2.5L I bought used & luckily it had already had the upgraded pipe installed. I actually bought the pipe & went to install to realize this. The new pipe has a new sensor "VOLKSWAGEN 07K906051". This pipe & sensor is located on top of the motor just right of the block. The sensor this guy showed in this video is located on the Manifold. It's important to understand how the pvc system functions. The diaphragm separates' the oil & air & when it breaks it causes oil to drain down into the manifold & get burnt & cause carbon buildup on the throttle body. So if the diaphragm was bad it's good idea to replace the 2 sensors that can get contaminated or clean them at least & then see if the throttle body has carbon build up & clean if necessary & then behind then behind the throttle body you can shine a light down into the manifold & look for oil & clean it. There was a bulletin released by VW because the p0106 code was showing up in a lot of shops. Here's the bulletin copied & pasted below. I've been dealing with this code on & off for 2 years. It comes & goes & doesn't cause any major driving issues but so I'm going to pull the manifold cover off & make sure everything is clean before adding new sensor's. Those diaphragm's seem to tear easy & while I love my Jetta this is a stupid design.
VW P0106
Diagnose and fix VW P0106
Shops are reporting a high incidence of VW P0106 trouble codes. And VW has issued a service bulletin 24-18-02 to address a VW P0106 or P3078 trouble code on the vehicles listed below. P0106 is Manifold Abs. Pressure or Bar. Pressure Range/Performance and P3078 is Throttle Valve Control Module Air Flow at idle too Low.
Vehicles affected by VW service bulletin 24-18-02
2008-2009 Rabbit 2.5L (CBTA, CBUA) l
2008-2014 Jetta, Jetta SportWagen 2.5L (CBTA, CBUA) l
2010-2014 Golf 2.5L (CBTA, CBUA) l
2008-2014 Beetle, Beetle Convertible 2.5L (CBTA, CBUA) l
2012-2014 Passat 2.5L (CBTA, CBUA) l
Cause of VW P0106
The VW P0106 code is usually caused VW P0106 cause is carbon buildup in throttle bodyby carbon buildup on the throttle body but the carbon buildup can be caused by a faulty PCV valve that allows excess oil to pool in the intake manifold which then damages the MAP sensor. Do NOT make the rookie mistake of automatically replacing the MAP sensor because this may be a simple case of carbon buildup inside the throttle body.
Diagnose root cause of VW P0106
Remove the air intake duct from the air filter.
Manually open the throttle plate and check for carbon buildup
Next, shine a light into the intake manifold and check for standing oil. If you see standing oil, you’ve got a problem with the positive crankcase ventilation system-see below.
If there’s no standing oil, remove the throttle body from the intake (you’ll have to buy a new throttle body gasket) and clean the carbon buildup using a rag and spray throttle body cleaner. DO NOT SPRAY the throttle body cleaner directly onto the throttle plate shaft. The spray can seep into the electronics and damage the throttle body. Always use a rag.
Reinstall the cleaned throttle body. Clear the code and test drive.
If you find oil in the intake
The crankcase ventilation system is designed to remove blowby gasses from the crankcase and route them back into the intake to burn with the air/fuel mixture. The ventilation system on these engines is designed to separate out any oil vapors from the blowby gasses. When the oil separation system fails, oil doesn’t get separated from the blowby and it settles at the bottom of the intake. The MAP sensor is located at a low spot and oil can enter the sensor, causing it to fail.
Remove the vacuum line from the MAP sensor and check for the presence of oil. If you find oil, replace the MAP sensor. But you’re not done yet. Perform the following test on the ventilation system
With the engine OFF, disconnect the hose running from the engine to the intake manifold
Blow into the hose. You should notice air resistance. If so, then the check valve is operating properly. If there’s no air resistance, the check valve has failed. Replace the PCV valve
Next, with the engine running, disconnect the hose from the valve cover and plug it.
If the idle quality improves, replace the PCV valve.
Remove the dipstick while the engine is running. If the idle quality improves, replace the PCV valve
Remove the oil filler cap from the valve cover with the engine running
Hold a piece of cardboard over the opening. The engine should suck the paper onto the opening. perly.
If the engine fails the ventilation test, replace the PCV valve. VW may or may not sell the valve as a separate part. In some cases you may have to replace the entire valve cover to fix the problem.
After replacing the PCV valve
Make sure you clean the oil from the intake. Then replace the MAP sensor.
@@wandameadows5736 Thank you for providing the service bulletin. I own a 2009 VW Jetta 2.5. I replaced only the pcv valve using the doorman part last year, May 2022. As of today, i've been getting the p0106 code. I've been cleaning the hoses, intake manifold, throttle body & map sensor for the last couple of months which has been resulting in oil residue.
I just purchased a new pcv valve, by doorman. Going to replace it again, clean hoses, clean the intake manifold, clean the throttle body and map sensor Sunday, April 16, 2023.
Hopefully this works. If not, i am just going to replace the whole valve cover. Maybe the whole valve cover with a new pcv valve needs to be replaced in the first place as stated in your bulletin.
I will keep those who interested posted.
@@alfredbernal8603 If your still having the P0106 code I found another bulletin on a software update that's supposed to reset the barometric pressure parameters. It claims the original parameters were to sensitive. I've had the code come on & go away on its own but haven't taken it anywhere to see if its had a software update because beside the mil coming on once a month there's no problems. I've hooked my scan tool up & read the live data before clearing the code hoping I could catch it when it happens but no luck. I read on a VW form that the pvc design was bad on these engines. Heres the link to the service bullitn static.nhtsa.gov/odi/tsbs/2014/SB-10069633-2280.pdf or if the link was blockled on here just search this term in a search engin "volkswagen jetta 2.5 software update 2014 TSB".
Yhe 2009 Vw jetta 2.5L has an warranty extension to 110000 miles on the MAP sensor due to a factory defect where the eng light will keep coming on. Call VW of america and talk to a customer service rep and they'll send you to a dealership to take care of it. That letter can be found on Google.
Should I clean or replace map ?
Clean it first. If it still acts up, replace it.
Gracias thank you
Thank you for this video sir, very helpful.
I highly recommend if p0106 appear again after replacing the valve (from Dorman) Buy the original cover, VW don't sell the valve itself, must be bought with the cover, for some reason in my Jetta 2011 don't accept the spare part from Dorman and bringme a lot of problems with throttle, clear code, drive two or three days to ensure (MAP related problems require some time to light up the check engine)
Hey buddy, thank you for such a helpful video. I bought a 2012 Jetta, the check engine light was on showing P0106. The car would accelerate very slow and then kick in in a few seconds. I replaced the sensor with the new one two days ago, cleared the code and the car started driving well. Today while I was driving on a freeway I got the same code again.
After watching the video I believe I need to replace that Dorman thing? Should that solve the issue?
Thank you!
Rav Ocean Probably, if you remove the sensor and find oil, then yes.
Skyhook Studios so I ordered the Doorman and replaced it today. I cleaned the sensor that I put new last time, I cleaned everything I was able to. The plastic on the old Doorman was the same color as yours, but it didn't have any cracks tho. I cleared the check engine light, drove today all day and I got the same code again. I'm really getting disappointed. What should I do?
Maybe you didn't clean up all the oil in the intake?
Skyhook Studios I tried to reach as deep as I could to clean it. I couldn't clean it fully though because it was unreachable. Any suggestions for that?
Rav Ocean if you pull the map sensor out again, does it have oil on it again? If it does then you might not have installed the PCV valve properly. are you getting the p0106 code again?
The problem isn't the MAP sensor itself, I own one an went through the whole process. Make sure the dealership you bring it to doesn't try to make any excuse to get you into incurring into any additional expenses, they are sharp.
Sergio Valerio 2008, 2009 and 2010 VWs are having the ECM reflashed for the P0106 because of a computer reading error. The video shows oil on the MAP sensor, as many others have found, but never do I say replace it. If you have this code and you have oil on the sensor, then the PCV breather is faulty.
can a dirty/faulty map sensor cause transmission issues (roughness/wrench dash warning)?
That’s what I got. My transmission is shifting hard and I got the wrench at the gear indicator on the dash. Comes and goes. Car runs fine when the wrench is not there. Check for codes and P0106 is what I got
@@randomghost4385 check your intake manifold, if it's dirty/oily, clean it, then replace your map sensor, check if it have oil on it. if it does it probably means your pcv diaphragm is damaged and leaking oil into the air intake. replace it. many videos on youtube for this for the vw 2.5
@@kumbackquatsta Thank you. I will check and clean before I start throwing money at things
@@randomghost4385 good luck. all my weird shifting has come from those three parts, usually the pcv diaphragm leaking causing oil to get down to the map sensor via the intake/manifold. all parts can be replaced with hand tools at home.
@@randomghost4385 heads up on the hose clamp too. best to get a hose clamp wrench, although can do it with other tools, it's just tedious
I just got this code today and except vcds said the implausible signal is intermittent. You think I could get away with cleaning any oil off the old map sensor and replacing the pcv valve to prevent more oil from leaking into the manifold?
You might be able to get away with that if the PCV is torn. The only difference between intermittent and permanent is the failure rates. In order to set a light the code has to fail 2 times in a row. Intermittent means that it has passed atleast once since setting the light.
Did it fix your code? I have the same problem
PIPELINE CONSTRUCTION CZcams yes, lights been off for almost a year.
Thank you.. and i subscribe
Hi do i need to disconnect the battery before doing this
It's not necessary. Just make sure the key is off and out.
So I guess there's no way to avoid going in to wipe off the MAP sensor?
It's tucked down in there pretty good. It's unlikely to get properly cleaned without removal.
@@SkyhookStudios I've never really done anything besides headlights, air filters or fuses but I really don't want to pay a shop.
I have replaced both PCV Valve and replaced the MAP sensor and oil still keeps getting onto the MAP sensor. Is there any other ideas on why the oil keeps sneaking in there?
Other then residual oil, the PCV is the only culprit. If these cars had turbos, then I would say turbo seals.
thanks, maybe i'll purchase another PCV valve diapragm and see it stops the leaking.
@@SkyhookStudios I've replaced the PCV cover twice now, haven't seen a tear on the previous one. Oil still getting onto the MAP sensor. I've clean the sensor, the intake manifold and the PCV hose the best that I could. Do you think there is another leak elsewhere or am I destined to replace the Engine Valve Cover at this point?
Tim Tan did you ever get this resolved? I’m having the same issue
Tim Tan did you resolve the issue? Same problem
I’m still getting oil in the sensor
Get an oil catch can
Did you ever get this issue resolved? Please let me know, I am having the same problem
Van Coll yes it was my valve cover
So you be specific, you clean the sensor by the throttle body and replace the diaphragm.
Yes, it worth trying to clean the sensor first rather then just replacing it.
Yeah ima just clean the sensor first.
I followed the instructions here and replaced my PCV diaphragm and it did look old and cracked. However, the check engine light keeps coming back with the P0106 code. In fact, it's always two of the same P0106 codes on my OBD2 reader. Could it be that I have a faulty MAP sensor as well? Anyways, great video man, thanks a lot!
Adam NK it's possible that the map is bad. If there was enough oil to mess it up, I would say yes.
I should update this in case anyone comes across a problem similar to mine. So I had a check engine light with 2 related codes: P0106 and P0106 (pending).
1) Followed the video here and replaced the PCV diaphragm and cleaned the intake where the MAP sensor was. MIL light came back.
2) Replaced the MAP sensor since maybe it was ruined by the amount of oil in the intake. MIL light still came back.
3) Took it in to the dealership to have it checked out for me and turned out to be a malfunctioning throttle body. They wanted $1100 to fix, I bought the part for $130 online and replaced it myself instead. Driven > 600 miles on the car since then and the MIL light has not came back.
Thank you for the video, I have learned so much more about what's under my hood following this video taking things apart. Much is appreciated and best of luck.
Adam NK What was the part that you replaced for 130? The throttle body?
Yeah, I bought a used TB online. I believe the tag that it came with same it was from a 2009 model. Keeps the Check Engine Light away so I wont complain.
From couple buck he jump up to 35 bucks lmao.
