- We discussed checking for boost leaks on your VW or Audi model. Boost leaks can be a big headache, but before you assume you have a boost leak, you should check to make sure you know that's the case. Otherwise, you might end up chasing your tail. In this video, we show you how to check with a scan tool and then helpful tips to pinpoint your boost leak.
------
NOTE: For older VW/Audi models in which you need to enter a channel number for live data you need to go to channel 115
Channel 115-3 - requested boost
Channel 115-4 - actual boost
Update - Since making this video OBDeleven has created a next-gen version that works with iPhones! You can still buy the android version if you would like. LINKS BELOW

Damn Paul, you got a boost leak in dem jeans.
+Brandon Fisher ha.... well done.
are they bilstein jeans? I think it's time for some new jeans haha
Those are blow-off valves...
You could blow some air in to the first pipe you find. Its important that you use your mouth though!
@@Deutscheautoparts How much is open thr. Body on idle? I have golf 5 2.0fsi and 11% open thr. Body, is that ok?
Like your plug of the new Mk7.5 rear lights 😃
Car just happened to be there with the lights on.
When you were referring to 'these cars'; pointing at the lights.
Nice work. 😃
Great video! I just bought the obdeleven and tried your testing method. When I did my test, I was showing 17psi the whole way. Didn't really have movement against the specified value. It was pretty much straight across the board.
Great vid, easy diagnosis. I seem to have a different version of OBD II since mine gives me PSI. However, I was under the impression that for specified value I would manually input the value and see how it behaves vs actual value. The specified value moves the same as the actual with a .3 variance when full throtle. I guess that means no boost leak?
Can a boost leak also allow the car to run lean and give vacuum leaks?
Hi , can you check the boost leak on the standard OBD11 or do you need the OBD11 pro ???
Thanks !
4:52 did someone else notice the suggestion word "xxx" :))) damn Paul
Thanks for the video. I have an OBD11 and think I have a boost leak in my S6. Will go through the process you outlined to test.
Is it possible for you to have a post map leak? I ask because my 1.8 TSI Jetta feels somewhat lethargic lately (especially after removing my Neuspeed power commander). Live data graphing doesn’t seem to indicate issues and requested/actual values are close. I did find it very odd though that the car only seems to be requesting around 9-10psi full throttle second gear pull... thought it would be a lot more even stock... it’s a manual transmission Jetta so wondering if the lower torque that the manuals have are maybe the reason why it’s only requesting 9psi
Mine is old and I do not get a list of anything I have to manually type in the channels I think you said 115 but then what’s the other channel or the list of values 1 - 4 do I pick to compare it to thanks
Does the A6 2.0t 2007 have a diverter valve i cant seem to find it
Insanely helpful video. Thanks!!!
Hello there.
I go in 01 Engine control module, and in Live Data on Channel 115 and the Values 3 and 4 are not in bar they are in Nm.
Why it is nit the same as you are presenting?
Or how can I search by name?
Thanks in advance.
My values are inverted is this normal? My charge air pressure specified value is 2bar, and my actually is consistently at 1bar. On high throttle change they cross each other kind of move together then return to their values. Is this normal?
Have you heard of p2261 error ? Apparently its a softcode for boost malfunction?
Where do i check for early signs of leak on an Audi A6 V8 S-line ?
Thank you, very educational
What cause actual boost high than requested?
looking for a working odis it needs to go on line to fix new parts install any one
My vw Scirocco goes into limp mode very regular basis now ,checked the code on my device it is P0299 what could be the cause please..
Does a3 have maf? Because I don’t see mine, I have a k&n on rn
My specified value remains WAY below actual, unless idling. Over 4 psi. Is there an issue here, like DV or wastegate or am I good?
What about watching the waste gate duty cycle?
what diagnostic scanner are you using?
I dont see the chart pictogram when i use channel 115 in obdeleven how come?
Hi Paul,
I have a A3, fsi 2.0 2006, 200hp,185000km.
I feel strong boost driving fast, so fare no need for check OBD stuff, still nice clip,
Thanks Johnny Sweede Guy
Hey, thanks for a good video. What if specified peak boost/power matches actual, but it gets there in a halted, jerky manner. Stock Mk7 GTI. My car does this and no other Mk7 GTI I’ve driven does.
Did you get this fixed? What was the solution?
My Specified boost has a massive silly spike, actual boost follows a normal profile. Any ideas. Isn't the specified boost the requested value?
what other tests are good to run while the car is running on OBD 11?
Just go all out. Most OBD nowadays have the option to check the whole system, at a press of a button. U can't go wrong.
Have an Audi A4 2013 2,0 tfsi 211 hp, is it anyone who know what the turboboost should be? (in bar)
is the "specific value" the one the car requires while the measured value is the "actual value"?
Thank You Paul for your beneficial videos. Could an overboost code P0234 be due to a boost leak? In other words the system is overboosting to compensate for a leak.
did you figure out this issue?
I'm also curious about this. Having the same issue. I've replaced so many parts (N75, MAP sensor, DV, some hoses) but no resolution. Many 1.8T peeps says it's sticky vanes in the turbie. And I do plan to replace the K03 in the next year....but dang how I wish that I could figure this out myself first
Mine are in mBar and I dont have an option to use a graph
Is there a difference when you drive the car or have it stand still and press the pedal?
My jb4 plugs into the obd. No other way to know? Some times I pull hard and others not so much. Sounds like a possible leak but maybe it's just drastic seasonal air temperature changes in the north east.
I've noticed the same thing with my JB4. Running map 3 myself. I just added 2 gallons of E85 to an otherwise full tank and it seems to be running strong now. Thinking it might be an octane thing.
Hey Paul, i have 2017 gti and when only the ignition is on i have a CEL and EPC. Obd11 gives me a passive code saying loss of crankshaft synchronization, but when i start the car the lights go away and the car seems to be driving normally. Any idea what this could mean?
This is as you might of found out due to timing issues and a stretched or poor tensioner or as simple as a bad crank/cam position sensor.
Can you make an updated video for the mk5
How do u get the graph bec it not there for me
I have a big vacuum leak on my 1.8T Paasat.. Car starts ...runs/idles fine then dies... I can repeat this three times after that the car just cranks ..almost like it’s flooded at that point....HELP HELP!!! Oh side note the brake pedal gets extremely hard to push....
Hello! Do you have any recommended location for tapping oil pressure? Thank you very much!
3 years later and never got a response 🙄😂
@@flipperzeronewbies probably cuz it's a stupid question. He didn't even say what kind of car. If I can't pronounce a person's name fuk em then
Paul,
I ran this test and got some interesting results that I'm having trouble finding an explanation for: at low load (at idle or when I let off the gas), the specified boost is 4-5 psi, but the actual boost is around 14 psi. Once the spec boost rises, the actual follows along with it and stays pretty close, but 2-3 psi above spec. Any ideas what would cause the high pressure at low loads? Diverter valve stuck closed, maybe? Car runs great, but this seems very odd. TIA.
I've got the same deal going on.
I've installed a go fast diverter valve. Car runs good as fuck. But my actual boost at idle is always 14psi. But as specified rises, so does actual. But back to idle, back to 14psi.
@@terrymansell935 @jason either of you figure it out?
@@terrymansell935 14 PSI is atmospheric pressure
The only places for a boost leak on the ea888 will be throttle body or boost pipes is there any other locations where boost could leak from
Spacer diverter valve like mine.
Will this work on a 2002 vw bora 1.9 uk
Hey I have a VW Golf Mk7 1.6 TDI DSG 2014.
My car is in Limp Mode Engine light is on and coil light
It’s not picking up power more than 30mph very sluggish
What could it be ??
Need help or advise on this please
Thank you...
Dpf
I’m getting a P0101 code ?? Is this related ??
Hi!
I can’t see the ”live data graph” on my obd11.
How to activate it?
go to engine channel, then go live data graph
So how do you pin point it ???
My specified on my mk5 gti is 200, and actuall is about 1110
Can you watch my boostleak video. Is that normal or what is the problem..😫
Are boost leaks and vacuum leaks the same thing? And can they be tested the same way
Yes hence the turbo vacuums at idle and boost under gas
I have a boost leak keeps going into limp mode where do I check it
What is the troubleshooting device you are using?
shopdap.com/store/vw-audi-scan-tool-obdeleven.html
I got weird symptoms out of my GTI. I get RPM spikes at idle, but iv'e got no vacuum seal leaks. Also unlike vacuum seal symptoms, this only happens when my car has been ran relatively hard. Like getting off the highway, but will usually continue until my engine has had a chance to cool down under operating temp.
Any luck with this?
try the n75 valve
I get turbo flutter or surge on my S3 on WOT. Is that normal or could I have a boost issue or wastegate issue? I don't think Carista can check boost.
Check the DV, might need to be replaced.
@@t58beare I just ordered a Turbosmart DV so I hope that helps.
@@JimBean365 I had the same exact issue, checked literally everything and only the DV was busted. And to view boost I use a JB4 with the app, which is quite useful.
Same issue on my mk7.5 GTI. Did you ever find the solution?
love ur camera so FHD
I did this and my actual boost measured 2.6 bar and specified measured 2.3 bar, is that normal? lol
Can anyone tell me if i would see the lag in specified value vs actual value since i installed an is38 on my Alltrack? The boost seems to reach the specified value, just late. I have the APR is38 tune for it. I just figured the specified value would have changed with the tune. Thanks.
Not necessarily being an APR team they're going to play it on the safe side so running the same PSI on a bigger turbo sounds pretty much correct to my understanding the only reason when people put ko4s etc on their car and running 20 plus PSI is because the tune is already set up for it, plus you got to think 14 PSI on an is38 is way different than 14 PSI on an is20
APR tune*
@@FoxiferTheWhite Thanks for the answer. I never looked at the is12. My obdeleven is showing approximately 2.7 bars. That's quite a bit, right? Not that I think that's the problem. My misfires are mostly on cold start and low boost as i drive.
You're pushing 40lbs of boost in an is38 😳 what are you 400-420 Plus whp?
@@FoxiferTheWhite I just have the ots apr is38 tune. I thought that was a lot of boost too. Its supposed to be 356bhp, i think.
Did VW stop making the Golf R?
Nope
Let me tell you something it's not only vw and audi it's also skoda and seat in some cases Chrysler and ford galaxy
I fell like my forge bov is causing a boost leak for my mk7. Sometimes the bov lets air out when im on throttle... have you ever heard of this problem before?
ChiTown On full throttle? If you partially release the throttle it’ll let off some pressure. Also, as revs rise, even at full throttle the car uses less and less pressure above 4500 RPM. It’ll peak around 20 there and go down to 15 around redline.
Willy Willy its weird. Like ill shift into the next gear and go back onto the throttle and some air gets let out
You ever find a fix for it?
Would a boost leak throw a CEL?
Not always. It could throw a p0299 underboost Condition but it's rare.
Our Passat has a leak (you can hear it under hard acceleration) but stores a code very sporadically.
How do i check this with vag com?
engine measuring blocks 032 i think it is,this has specified and actual its listed as egr but it is maf readings
then channel 10 or so is map sensor
Can you retrofit a 7.5 infotainment in a MK7?
Its likely possible but this is not something are going to work on
I have a 2003 VW jettea . Sometime will not go reverse . Can you help me. Why
Not seeing the graph on my obdeleven I have the full subscription huh
Me neither. I think they moved it to "Charts" but the problem there is that you cant search for "Charge pressure", you have to scroll through and infinite list, TWICE.
For the amount you pay for the adapter and full subscription, im really disappointed at how bad the UX can be on the app.
Well I know I have low boost because it threw me P0299

Paul i writting you back on email i wait you answer for my stage 2 !!
Love your videos, but you guys really gotta get a better website. It's unusable and is costing you business. I would purchase my parts through you but it's so terrible I buy elsewhere.
Sorry we have been dealing with a new site change over that has had a few hiccups. If you have any future issues be sure to contact us so we can get you taken care of.
Whay if you hear a popped ballon sound under boost? 🤣😂
jesus how do you carry your phone
That's a tablet.
I’m sure it’s a good explanation… but for me it’s just too long and I fell asleep. I’ll watch it back another time, for now I’d rather try something else.
Im not happy about obdeleven requiring network connection, if I saw that before I bought it I would not have purchased.. its basically a piece of shit, not everyone and everywhere has internet connection, and this ball of shite let me down when I needed it most.
A year late, but a lot of places have free wifi that you can just park outside of and use.
this video has so many views....... lol. and there are not too many audi/vw cars on the road... just shows to show you that german engineering is overated
There s crap ton and ppl with other cars can also just sesrch up boost leaks and this video will pop up
American cars are the worst. FORD = Fixed Or Repaired Daily.
Wow this talk to much stay on subject lost me aftet the first minute
It's OBD 2 not 11.Roman II not 11. 😂
