I haven't taken anything apart in the engine compartment, at least not prior to the codes popping up. Can I simply clean the MAF sensor with some sort of electronics cleaner? I ask this because I noticed that there was a lot of debris inside the airbox, past the filter. I cleaned all of it out, but womdering if some may have gotten through to the MAF downlline.

I found a pic of the cam sensor on an on-line store. I will see if I can identify it at home tonight. Thanks for the info.

 

After going to an import repair shop and having them tell me that it would cost about $800 to replace my MAF sensor, I repalced it myself. They said that it would take three hours to do it...I did it in 5 minutes. Another rason that I hate most auto repair shops. Anyway, I still have multiple codes popping up...they all read as "fuel air meter" codes. I've briefly checked all the hose and conection in the engine bay and didn't see anything worn, cracked or loose. Any other ideas to try? The camshaft position sensor code didn't come back as afault, so I won;t replace that.

 

If the errors are lean it could be a vacuum leak.

If not, could be O2 sensor.

 

After replacing the MAF sensor, Bank 1 Sensor1 O2 and changing out the spark plugs for good measure...the ol' 2.7T is running as good as new again. Thanks for the info and troubleshooting! It's nice to be able to punch it and take off again!

 

These codes popped back up after I replaced the MAF sensor and replaced O2 sensor #1 bank #1 the other day. I've had the cam shaft position sensor checked and it was good. Another note: I get a slight exhaust smell inside car with the windows up or down now. Any suggestions besides getting rid of this piece of crap car? Should have stuck with another Jeep product....

 

is the smell like eggs?? if yes then its the catalysts

 

No egg smell. Been there and done that before. It is not the cats. Took it to a very reputable custom muffler shop in town and had them look at the exhaust. It smells like exhaust you would smell if the car was in the garage.

I keep getting codes that say too lean and too rich. Here's what is coming up now:


P1136 - Long term fuel trim add fuel Bank 1 too lean
P1131 - Bank 2 sensor 1 resistance too high
P1129 - Long term fuel trim mult, Bank 2 system too rich
P1127 - Long term fuel trim mult, Bank 1 system too rich

Could bank #2 O2 have gone bad at the same time?

 

heres the latest:

Took the A6 to another german repair shop and they ran the codes. These popped up:

17800=P1392 - Camshaft position sensor bank 2 (G 163) open or short to B+

17966=P1557 - Charge Pressure Control (positive deviation)

This guy said that I needed to replace the camshaft sensor on bank 2...makes sense. But when he said that he needed to replace the intake manifold gasket and the two gaskets on the heads....something didn't seem right. I looked at the possible symptoms online for this code and a few are mentioned. Most notably is the possible problem with the Solenoid Valve for Boost Pressure Control (N75).
Before I spend another $600 having him replace all the gaskets....which for some reason doesn't make sense to me...I don't hear any sucking or hissing sound that I have heard before with worn gaskets...I'd like some other input.
