A6 C6 EDC16CP34 FAILING TO REVERT BACK TO STOCK
Story time, sou car came in my workshop to fix after one tuner, cruise control stopped working also a lot of other problems..
fault codes: 18020 - Engine Control Module Incorrectly Coded first tried make bdm backup with ktag, checked checksum and its wrong (i actually know that it will be wrong because its not first time of fixing car after someone else) Okey to start over i flashed stock sgo with odis e and it failed for none reason (14.2v) Now ecu not resounding that's normal next... Corrected bdm read checksum and flashed back all ok car running my question? How to revert to full stock? And maybe someone more experience can tell me why odis flash fail, does this happen to all modified ecu?? Meybe try again because now ktag read bdm with corrected checksum?
