I have a 1999 Audi A4 (2.8). I tookmy car to Autozonefor them to run the OBDII turns out the tech there thinks I have a bad ECU. Is that possible? Codes ran where p1136, and p1138. I read it could be avacum leak. Any ideas??

 

Check all the vacuum hoses.

 

P1137 is the problem EVAP canister purge valve and as stated an air breach in that system

 

when the ECU is most of the time the car will not run at all .

 

Thanks for all the replys. I'm going to go over my vacum hoses this weekend. How can I tell if my MAF is bad? Is the EVAP canister purge valve expesnive to replace/fix? Can I do it or does a dealer need to?
