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!

I think problen is immo data not match on ecu and dash.

That is why windows not work, component protection.

Regarding the abs/epc light probably when they swapped dash abs longcoding got lost.

No comms with module 25 i think is because that car has no separate immo module, it is inside dash module 17.

From your history i assume that car got dashboard damaged and they swapped it and made immo off in ecu. All problems derive from same action.

Hello and thanks for your reply! This ABS is soft coded, its old one, no long coding here. I have coded it correctly according to car option list, so thats not a problem.

I am also sure all this problems come from corrupted/not matching dash.

But how can i fix the problem now? Can someone help to match the files?

Can someone extract dash PIN from micronas + 24c32

ok with odis is a geko account it's possible
the pin is not enough to code the meter
and since you don't have the original one it's not possible
do you have a photo of the cs read in xprog?

VCDS, ODIS, Xprog, Carprog, Zedbull, kess, ktag, and lot lot more of basic tools.

Dont have VVDI2.

I can read from other topics that people manage to extract pin and everything with just micronas + eeprom dumps.
