If the part numbers are the same, you should be good

 

hey hartsoe sorry i didnt respond to you sooner but i just wanted to meet the guy first before i gave out his ****, but his name is flyride337 i believe and he is on the Vortex forums. But i just got back from replacing my ECU and everything worked except it didn't fix my problem.

So now i am back to square one of my problem and i still have my CEL. The guy gave me some insight about the problem. I am still getting all of the codes that i posted about earlier in this thread with the new ECU. So now that i am convinced that i have a wiring problem can anyone help me find a decent wiring diagram? I have been looking for ones before and i've looked at the ones that are in the bentley manual but they are not detailed enough. Im looking for one that gives where all of the grounds are located in the car. Or atleast locate in the wiring where are of these problem systems are interacting and where a common loose ground could be.

 

Sounds like it's time for that car to get hit by some Jewish lightning. Is an A4 really worth all the hassle?
