Hey guys,
A couple weeks ago I tried helping my buddy out, he has a 04 A6 2.7T that somehow stopped running after he was ''messing'' around with NefMoto, his car would not start, long story short, I ended up bringing my spare ECU to his house to see if we could get the car to run with my M-Box since his car had a Hitachi MAF sensor, after removing the small guide from the bigger connector on the ECU off I put my M box in his car and flashed it with Galletto, we still didn't get his car running.
Anyway, yesterday I tried putting that ECU in my car and it won't start, NefMoto will NOT connect to it and I can't even put it into boot mode with Galletto. Any ideas of what else I could try?
04 A6 2.7t uses 7.5 with immobilizer. most likely you might have fired your m-box by plugging it in
