I am new to the forum. I am looking for advice on what to do about the MAF sensor on my 03, A4, 3.0L. I replaced the sensor once and theCEL came back on and I did a diagnostic test on it and the MAF sensor was the only code that poped up. Here is the thing I have a aftermarket supercharger.Is the supercharger pushing to much air through the sensor and setting off the CEL? If so is there an upgrade MAF sensorto correct the problem?

 

check on audizine with 3.0 king. there are a few others who have a lot more knowledge with the 3.0 and supercharger kit!

do you have PES?

 

Thanks for the quick reply. I will checkaudizine with 3.0 king.

It looks like PES but I don't know for sure.

 

What code are you getting? If it's a 17550 code, go to scaudi.com and do a search of all forums for "17750". Skiball and I have been having the exact same problems.
