Hey guys,

im new to this, flashed a few cars via OBD with KESSv2 but got in struggle with this ECU on an A3 1.8T from 98.

I tried NefMoto with KKL, VCDS cable in dump mode and couldnt connect to ECU, connected to 0x01 but failed connecting on 0x11, did also remove both dash fuses but both didnt help.

Beside of VCDS, KKL cable, KESSv2 i also have Galletto1260 but it seems to be useless because its for the 29F400 and 29F800 chips?

Due to this i ordered a PSOP adapter for my Willem5 and wanted to read/flash, did read a backup and tried to erase chip, tried to reflash and it seems my backup was corrupted.
Now i can reflash the corrupt backup to chip but the orig-dumps downloaded online are´nt possible to be flashed and my Willem keeps telling me error at address. 0x0....

Car doesnt fire up and VCDS does not recognize ECU anymore

What opportunities/tips/tricks do you guys have for me right now?

Regards and Thank you =)

would this help, as i dont have access in VCDS?

for now i installed a 06A906018CG ECU but we seem to have problems with the Boost Control, car starts dropping boost at 2700rpm.

And if i put 12v to pin43, will i be able to fix it using NEFMOTO, how should this work when it doesnt recognizes the ECU anymore

Regards
