Hello guys!
I have an interesting car here.
Its A3 07 year 2.0TDI. Dash 8P0 920 931 E. ECU EDC16U34 (inside eeprom 95320)
Owner bought it with ABS and ESP lights on (wrong coding error 01044), windows not working and no com to 25 (Immo) module, but the car starts and works
I have understood that there is some problem with immo (found numerous topics of people changing dash and having ABS problems later on)
As i mentioned, no communication to module 25. There is com to ECU and DASH no problem, but when try to read immo data OBD says unknown version or corrupted dump.
Took out ECU - read eeprom 95320, its IMMO OFF, car starts and works.
Took out DASH - read and decrypted EEPROM 24LC32 with xprog micronas module.
Tried making IMMO ON file using EDC16 calculator - doesnt start, so there is some problem with dash.
So the question is, is there any other immo box on that car or communication is lost because of corrupted dash? Once again, 17 Instrument communication OK, 25 Immobilizer no communication.
Can someone check my dumps and tell me the easiest solution to fix the problem? I think DASH eeprom is corrupted.
I have attached 4 files:
1)ECU eeprom IMMO OFF (ori)
2)ECU eeprom IMMO ON (mod)
3)DASH eeprom crypted (ori)
4)DASH eeprom decrypted (XPROG MICRONAS)
Huge thanks to everyone!
