Great video George😊👍. Thank you for sharing your knowledge. In over 6 months I had Lag when i push acceleration. Lately drive train pops up every time the accelaration reach 2000 rpm. After watching your video, it motivate me to check my map sensor. I can tell my map sensor was clogged and cover with 1 cm of oil and carbon. After cleaning the sensor with turbo and egr cleaning flluid and the hull in the intake manifold. My engine work very smooth. Now my car accelerate very good and the drive train errors disappear. My car passed 155000km. I think I too need to do a total cleaning of the intake manifold. Again thank you much. You have saved my day :-))
I've been chasing problems in my 1995 toyota corolla, I don't know why I didn't just start with this. But atleast she got a new set of fuel injectors, fuel filter, plugs wires and a good oil change. Kinda impressive she has 250,000 miles still runs smooth as silk and am sure she still has alot of life left in er.
Great 👍 Video George! I have a 2010 318d with a N47 engine and you motivated me to check my MAP sensor and I was shocked how clogged up it was. I just made a video with my MAP sensor clean and uploaded it to my channel. I will also need to clean the intake manifold as you have shown in your other video. Cheers!
Glad to hear buddy!
Top notch videos mate, really helping me sort the efficiency of my N47 engine. I have the 320 e92 M sport coupe👌🏻😎
Thanks for great videos, I'm driving a 2012 bmw 318d 2.0, check engine light came up with P0406 EGR, so I cleaned up the EGR valve along with the intake manifold and the EGR cooler plus the MAP sensor, the light went out and everything seemed OK until a few days later the light came on again, only this time the code is P046C, again for EGR, the EGR valve is clean and it's flowing nicely, not sticky anymore.
Any ideas?
great vid mate so important and such a small job i didn't know about but thanks to you i will do mine tomorrow
No prob Joey, you’re welcome👍🏻
Came across your channel by pure chance, GLAD I did! What a really useful informative channel, really good, keep em coming georgie boy 😁😁😁
Cheers mate!
Hi George, while cleaning the MAP sensor can some other spray be used i.e brake cleaner? Would it harm the sensor?
Thanks for the you. It was really helpful my map sensor condition was even worst.
Thank you! I don't have MAF cleaning spray or contact cleaning spray on hand --- could I use rubbing alcohol (isopropyl alcohol) in a spritzer bottle and then let the MAP sensor dry out before reinstalling it? Please advise... Much appreciated...
It is a good idea to clean it every so often however I would be very careful with tellig people to stick a screw driver in it! for 2 reasons, 1 you might force the carbon down further inside and 2, if you stick it down too far you may damage the diaphragm and break the sensor. I personally would not use a screw driver, rather a soft brush or a cotton bud as much less risk of causing damage, or better still just let the cleaner disolve the gunk the spray it out with the nozzle. These components are fragile and not cheap either.
Hi George, I watch your videos from time to time and find them very useful. I have a problem smelling like the exhaust in the cabin of my E90 N47. What could be a problem and it would be nice to post such a video to check all possible problems when it comes to the smell of exhaust gases in the cabin.
My bmw 116d doesn't have a bolt for the map sensor it just click in place but there is a hole for a bolt like yours. Am i missing a bolt?
I appreciate the information on how to help keep a car running well. I don’t have a diesel, but this is still a cool video nonetheless because I do have a MAPS 🙌 You’re appreciated!
Glad to help!
Hi george , i have an issue with my bmw , from 1500 rpm engine change sound ? Do you know what could be
Just cleaned my MAF and MAP and of course I am imagining results, but it feels good. Thanks!
Definitely doesn’t hurt Paul!
@sheparddog117 fuel pump
@sheparddog117 definitely is a faulty fuel pump , replace the fuel pump , before that just read some codes and check if anything relating to the fuel pump shows up
@sheparddog117 Does fuel pump solved it sir? Or something else was the problem?
George, do you think that simple cleaning of this sensor might resolve a 25d100 code? (charging pressure sensor signal open circuit or short to ground) It's associated with a Drivetrain Malfunction CEL and engine shuddering under maximum torque demand.
There are also codes --
25d000 charging pressure sensor signal short circuit to b+
259100 exhaust temp sensor upstream of catalytic converter signal deviation too high
259200 exhaust gas temp sensor upstream of diesel particulate filter signal deviation too high
290b00 air mass system measured air mass too low
-- which I consider to all be daughter codes of the actual malfunction.
Cheers.
Did clean mine on my Isuzu Dmax 07, warning light still on, short circuit?
Yeah I thoughtlessly blasted air (really not good as the MAP operates using a sensitive membrane to measure air pressure) and carb cleaner near the sensor while cleaning throttle body... threw a CEL after and ran terribly: high idle, late shifting, power loss, running rich etc. After cleaning the (very clogged) MAP and idle air control, she runs wonderfully. Great and easy thing to do once a year. 👍
3:01 is what you are here for
God bless
Thank you 👍
Thanks for the video , you always make things sound easy and informative
I have the same car 520d n47 engine been told that my swirls are carbonated badly , how much parts and labour would it cost ?
Thanks
No problem my man, glad you like them!
Parts and labour for what? I can do you an EGR delete and intake manifold clean👍🏻
Hi mate
Thanks for the reply , how much roughly will you do that for?
And where are you located as I'd rather come to you since I watch your videos on a daily
Contact me on 07502299743

Thanks
Send me an email mate: GeorgeAusterberry@gmail.com
i have seat toledo 1.9 tdi 110hp 1999year not have power like all after 3rd shift should to clear my maf sensor ot what please someone to explain me :)
My so has a 2008 535xi and I can find the MAP sensor but not the MAF. I read that it might not have one.
Any idea on how to unplug that connector??
thank you !! anyway how is your engine room so clean?
I cleaned it haha. Will be doing a video completely detailing it soon!
Excellent clear advice again..
Glad it was helpful!
I wouldn't use Carburetor cleaner I believe the chemicals are too potent for the sensors.I prefer MAF cleaner "Mass Air Flow" electric sensor cleaner.It's more compatible to the sensitive parts.
You shouldn't use MAF sensor cleaner either, you need to use electric parts cleaner
THANK YOU! I don't have MAF cleaning spray on hand --- could I use rubbing alcohol (isopropyl alcohol) in a spritzer bottle and then let the MAP sensor dry out before reinstalling it? Please advise... Much appreciated...

@@jimb1580 rubbing alcohol should be fine.
I just use brake cleaner dammit
great video! do map sensor of petrol cars gets dirty same as in the video?
They can get covered in oil but not soot
Also for g30 540i 2017?
Hi mate, cracking video, do you have to take the sensor off the cable?, or can you spray while its still atrached?, mine in my insignia will not come off, tried undoing the clip an everything but its stuck so will have to use the spray while still attached haha
Can leave it attached
@@GeorgeAusters thank you for replying so quick, the idling is a bit rough now but im waiting for the spray to come to clean it out properly 👍
Would have liked to hear before and after idle or something
Out of interest when you have your 520d mot what is the exhaust smog figure ?
Haven’t a clue
Is a dirty MAP sensor often the reason for the Engine management warning light to come on?
Any symptoms?
Hey mate, is there a specific reason you didn‘t undo the connector and clean it on the workbench? Or was it just not necessary? After this video, I‘ll be taking a look at my MAP on the Alpina D3 for sure (same engine only the BiTurbo Version, that‘s why I love your videos, keep up the good content :-) )
No need to remove it
Instablaster...
I also have a D3 Biturbo and cleaned mine today. Want quit as bad as this one but still a good wipe over for piece of mind.
Is it safe to apply any carb cleaner spray on MAP and MAF sensors?? No residue?
No
I have a 320d n47 engine. Engine cold time 1500 rpm no good performance. Engine hot time good whats is the problem ?
this can throw a warning light on the dash also just clean all 3 sensors MAP MAF EGR just to eliminate these problems 👍
hi , i have 2001 e46 320d and it has no power oh torque and barely even climbs hills on first gear . only if the revs get about 2.5k then it has power and boost , would a faulty maf sensor cause this?
I have a very similar problem ! Does it also have a terrible fuel economy ??? I believe it’s MAP or MAF
Faulty egr valve caused this on my rover 75.
Even if this single process does not make the engine feel more powerful or efficient, the sum of all these things, O2 sensor, MAP sensor, crank case breather valve etc make the difference between an old engine that feels old and an old engine that still feels pretty fresh.
And earlier or later such a sensor alone can actually make a big difference, why wait for that, if you can prevent it for free?
Hi, what spray are you cleaning it with?
Carb cleaner mate
@@GeorgeAusters is throttle body cleaner the same as this !?
Basically
@@theroyalone7588 It is not, don't use throttle body cleaner, it'll actually say on the can dont use on maf/map sensors.
@@-Wreckanize- thanks a lot
29 dislikes from BMW diesel engineering department. 🤣
Hi George. Will this stop the 'drive train function' notification to stop coming up? Mine keeps coming up & cutting out. I've had EGR valve replaced a couple of times but it continues to happen. Think I'm getting fobbed off
Depends what the fault is but worth giving it a try
Thanks mate. Been advised now it needs wiping off at a garage. Endless £££
I wont even think on driving anything solid inside a MAP sensor tube, they operate by detecting tiny flexes on a chip at the base of the sensor product of pressure changes in the outside. If you push anything against it you are going to decalibrate it and be screwed. I just blast them with contact cleaner, safe and cheap, but thats me.
Can i use maf cleaner on the map sensors aswell?
I have 2.8 v6 turbo.
Yes
Ok great. Thankyou.
Yeah, it's what you SHOULD be using. Do not ever use fucking carb cleaner like this clown in the video.
Thanks.
Should I disconnect the battery before doing it?
No need
is a map sensor the same as boost pressure sensor? and could this cause power loss now and again? with smoke and soot coming out the exhaust on acceleration?
Manifold absolute pressure sensor.
@@GeorgeAusters does a faulty map sensor cause low power when i turn the car off and on i get full power for maybe 5 mins then it goes again feels the turbo isnt kicking in
If your going to stick a screwdriver in the end to clean the carbon out it would make sense to have the carbon fall out of it instead of into it. Bad form.
This just popped up. Used to do this on my audia4 and the Audi guys used to laugh at me and say it’s pointless to clean the map and maf sensor yet I always felt a difference after
I just cleaned my MAP sesnor on my 2017 Kia Rio, and my MPG went from 14.5 to 22 in city driving of 3 miles after cleaning.
LETS GO!!!
Can i use brake cleaner?
TO clean?
You didnt answer 😵💫
Mine was covered in the universal high temp grease🥰😎
Wow lol
Can you use wd-40 for this or is that a big no no?
Yes can do but not sure how well that will clean it
NO. DO NOT use WD40 on ANY sensor, EVER! Why would you do that?
My understanding is that you should only use MAF cleaner on either MAF or MAP sensors as carb or brake cleaner is too harsh to clean a sensor with. Look for a can of MAF cleaner...
No difference to electrical contact cleaner really
Carb cleaner kills MAP it too agressive. Better to use brake cleaner
Where is it located on m47?
I think theirs a video in your ads
Where is map sensor on a 2005 ford 500 3.0 V6 duratec ?
In the intake manifold
@@GeorgeAusters Thank you I have look inside the intake manifold. Don't see it this has been a challenge lol.
I already replaced the MAF sensor but the issue is where is the Map Sensor I look at the intake don't see Map Senor
Great job, just be careful poking a large flat blade screwdriver into the map sensor as most of them also have a little heat sensor at the opening which is very easy to damage. All diesels cars need the major service of taking off the inlet manifold to clean all the egr/oil combo buildup which definitely effects performance and efficiency of your engine, an good example of anti pollution devices causing more problems and long term pollution than without all that EGR junk in the first place.
sei inglese?
I DIDNT NO U CAN CLEAN THOUGHT U HAD REPLACE THNX
thats one way to brake map Sensor it and mate just use carb cleaner or map cleaner you dont want to bash it with something it will brake it
Good video
and don't scrape inside a map sensor
Could this cause the car to hesitate & lag?
My 330d on acceleration thinks about it for a second or two then takes off when the turbo kicks in.
At 60mph it sounds like it’s fighting. I’m sensing a clog somewhere
Same story!! 320d 150hp. It also has a terrible fuel economy
@@antoniocignozzi1477 you tried throttle reset?
@@mister.c4631 how do you do it ?? On diesel engine ?
@@antoniocignozzi1477
Yes mate easy.
Make sure car off all together
1.Firstly put your accelerator flat to floor
2.Turn the key to position 2 (where all dash lights on but don’t start car)
Count 12 seconds
Then turn key back to off making sure you pedal is still down.
Count to 12 again
You’ll hear a click from around the accelerator area
Once you hear that, start the car!
@@mister.c4631 did not know this cool feature! Thanks a lot I will do it as soon as possible !!! Thanks again !!
Any guys here have any knowledge on why a diesel would have a uneven idle ?
egr , fuel pump or injection pump
Mr330d bad spark plugs 😉
Glow plugs or glow plug controller
pressure/intake regulator on the pump. just fixed mine.
Map sensor
kept the power connected?😂
great video if it was 3 mins.
Pointless to clean that MAP sensor without cleaning the throttle body that you just removed it from and you should be using electronic parts cleaner and not carb cleaner.
Thanks, Bryan --- could you recommend a specific brand of electronic parts cleaning spray?
Far too many ads, however.....my Jag XJ 2011 kept going into limp mode until I cleaned my MAP sensor. Been brilliant since.
Worth noting that the MAP sensor is a diaphragm so you shouldn't ever stick things like screwdrivers in just in case you damage it. Stick with the cleaner.
I cleaned mine last year
You DONT touch the VERY sensitive wire part!! I bought special Mass Air Flow sensor spray
Just spray the wire part (do not touch it) And leave it to dry before putting it back
Are you talking about the MAF or MAP sensor?
George Austers oh sorry I’m talking about the MAF sensor
Not exactly sure where the MAP sensor is on my corsa d. I removed the whole air Intake Control Valve and cleaned it.
I think the the sensor is on this but it’s fixed
@@jamesmcrory8990 my Subaru has both🤔
Most modern cars should have both. MAP is Manifold Absolute Pressure
@@jamesmcrory8990 LOL good luck I'm doing the same thing this week I swear these things get harder and harder to work on every year pretty soon the average Joe like me won't be able to change the oil😂
6:20 ASMR 🤤
Mate you need to watch this on someone elses computer and see if its satisfactory for you. Its intermittent its dodgy man. I cant even watch it I tried to go back refresh but its not my computer its the video and to have this much interruptions all the time is why I think your not getting good numbers of people watching your videos as if they see ONE dodgy video we all think all your videos are dodgy.
Intermittent... What do you mean?
@@GeorgeAusters Its like a record with scratches on it. its not refreshing it might be because your videos have adverts and I use ad block its stops and starts and it annoying. 0:46 to 0:47
Kiwi Exotics yeah probably best not to use Ad Blocker then mate. I’ve watched it with no problems, the same as everyone else👍🏻
MAP sensors are on petrol cars MAF sensors are on diesels
Lol both cars have both
@@GeorgeAusters 😂😂😂
