Hello everybody!
I have touareg 2012 year with 3.6 FSI motor.
Last time, car keep showing check engine with under errors. I tried to change air filter but problem havent solve. Please tell me where should i check? How to check MAF via diagnost progam? Should i clean MAF sensor by special cleaner?
I have ELM Bluetooth and Carista app and VCDS cable with a laptop. At this time, i keep clearing errors and continue driving, when error coming, transmition have stupid behave.

Thank you in advance for any help!

Check for air leaks between MAF and head. Smoke test intake manifold..... or spray carb cleaner around it to see if the idle increases as it gets sucked in through where the leak is.

 

[volkswagens-for-life]

Carb cleaner is easiest. Hit up the whole upper half of engine. You'll hear idle go up

 

[New2Tregs]

Definitely check to be sure either end of the intake tube, from MAF to throttle body, haven't unseated themselves. Especially on the throttle body side.

 

[hoang.son911]

Hi everybody! Thanks for your advise. I came to service to check, they printed all fault codes and didnt advices anything. Then i came to another place and did smoke test with smoke generator, but didnt found any air leach…

 

[volkswagens-for-life]

Attach all codes found. What system did they use to extract codes?

 

[hoang.son911]

Should i buy new MAF sensor and replace it? My MAF dated December 2011. After replacement will i need to do any adaptive coding work?

 

[volkswagens-for-life]

Post codes

Why are you suspecting MAF failure?

If you do decide to throw a MAF at it there should be no adaption afterwards.

 

[hoang.son911]

Unfortunately, codes in russian. I think they used russian version of VCDS.
I see 3 codes:
5668 - G70
P0101 00 [111011101]

12827
U0401 00 [00001001]

336397
U1123 00 [00001001]

Hahahah, ask and he shall receive right?!

 

[hoang.son911]

👆

Leakage air must be 0?

 

[SaVAGeSoot]

What does a MAF do?

 

[hoang.son911]

Hi! I came to 3-rd services. This time they advice to change valve cover and gaskets. Do you think they are right?

They're probably thinking you have a bad PCV diaphragm in the valve cover. Gasket gets changed with the cover.
Are they right? No way to tell on the net. Sounds like they are just going to have you throw parts/$$ at it to see if it fixes your problem..

 

[hoang.son911]

I agreed to change valve cover at service, but after 100km error showed again
They checked with computer and said vaccum is good.
Did a smoke with smoke generator test but doesnt see any smoke came out.
Now service suggest me to change MAF sensor Bosch.
Do you have any more suggestions for me?

Not to be rude about it, but I can only suggest at this point to find a mechanic that is familiar with the Touareg so hopefully they can diagnose it correctly with the right tools.
Best of luck.
