Hi

I have this car and with ECU Internal Fault error, readed with examiner. Error can't delete. Car working with this state no problem, only display error message
Anyone have idea what is this problem? I disassembled the ecu, no damage inside, no soldering problems.

Maybe software problem? ECU have two eprom B 58 539 (27c256 i think) and two 93c46.
Somebody have eprom dumps for comparing with mine?
ECU details:
0 281 001 712
M717 7T7

regards
Tom
