[TuningQ]

hello!
is anyone able to help me with KTAG and ME7.5, Friend of mine lkoaded in a modded file using mpps. file loaded in 100 percent, went to start and no start!
Went to reload in old file and ecu not found! Long story short i have his ecu here adn i have read The backups from Ktag howsever i keep getting error after read of checksum error.

All help is appricated


i have attached my bmd read/ the stabndard files and the mod i paid for

I havnt came across this beofre that the file loaded fully then wont pick up ecu

i think you mod an already mod file, you might need to search for ori bdm file for your ecu, i'm just guessing , someone will verify

[TuningQ]

EVEN IF MOD ON TOP OF MOD, should it still not load in and start? i have dione this many times

[TuningQ]

can anyone help?

i had bad experience with vag car, i sent file to tuner for mod, but file was already tuned ( idiot tuner ) loaded file, non starter, had to buy new edc16 ecu, maybe your situation is different, just my 5 cents, i hope you get it solved

i hope i can find someone to help me fix this ;/

you have to desolder 29F800BB and write original file, then solder again flash on ecu

Its easy to write in bootmode without problem,
Just bootwrite the file you read at first
