Hello i have tried to read Audi S4 ECU 8D0 907 551C tuned by other tuning company and after this car won't start and can't read it by VCDS. I've read it two times and files was different both times... After this i have tried to write original file but get writing error at 13% every time... Tried to write the files i've read at first and it's writing without errors but again car won't start and can't read it with VCDS. Can it be some kind of tuning protection or... I am reading and writing in bootmode.

they desolder the stock flash, and put a "socket" in the place, so you can change the chips/flashes fast. You need to open the ecu and you will see. |

If you can't read/write in bootmode, your harness is no good, there is something wrong with your computer, or the ECU is fried. Get a spare ECU to test your setup.
