View Full Version : Audi S8 V10 MED 9.1 not start

1st October, 2018, 10:39 AM
I read master and slave with kessv2 5.017 succesfully, made mod on file, then wanted to write back master modfile and writing failed at 84%. Tried also recovery with kess, no luck, again fail on 84%.
Then opened the ecus, wrote over BDM the fixed flash files, car still don't start, but the dumps look ok to me, also did checksum.
Car is not starting and the gear indicator is still highlighted like in programming mode.

Can anybody help, i attached the bdm dumps after programing flash on table, and the 2 Kess reads, maybe anybody know a solution.

ID is:
HW 0261S02578
SW 1037391612

Try flashing this one to both ecu via OBD with kess.

Thanks mate a lot! I will try then and report. But my i think my kess actually made the problem to the ecu, and it will happen again for sure when writing it over OBD. I will also look for other tool for obd-writing.
Is there maybe any "on bench" solution, writing with ktag or bdm100?
