Audi A6 C5 dash eeprom 93C56 corrupted

[karl Martin]

Hello

I believe that the eeprom of this car is corrupted. The car is Audi A6 2.5 TDI from 4.1999, with analogue instrument cluster and with ECU 4B0 907 401H D33.A, Bosch 0281 001 781.
As far as someone who help me in this great forum, the ECU eeprom doesn't have code.
So I read 93C56 dash eeprom and I get the code 6413 or 1364. Neither of this SKC work to make login in the Engine, as per Ross Tech instructions in order to match the diesel Pump

Can someone please check if the eeprom on the speedo 4B0 919 860E UN4 is corrupted? And in that case correct the file?
The car has about 221 000 km.

Thanks for the help

Pin from dash eeprom is 1364.
What do you try to make on this car?

I'm trying to match the new refurbished diesel pump. It is a car from 4.1999 and someone told me it won't need. But in facti the ECU can't accept the pin. So last night I try to write a new file with immo off to the ECU 4B0 907 401H. But I didn't test it yet.
Someone told also that the file is corrupted. So I don't have much options. I have already replaced the dash with another immo3 and I could match the keys and the imobilizar light did go away but still the car doesn't run

Do you believe that the file is not corrupted?

Thanks for your help. I'm very frsutrated with this situation

I think your car is with immo 2 but not immo 3 generation.Why you try to login in ecu when there are no pin stored?
What is fault codes in dash and ecu?

Thanks for your help today and before. You are one of the few who help me. Because the car is far away, I just need to check if the dash eeprom is good, because I've already write the immo off eep to the ECU, and just to be sure I need to check the dash eep before

Putvcds on ecu, on bench and see if you have immo error... Of not, your off is good. Doesn'tmatter about ipc and keys not being programmed. Boa sorte!

Thanks to all who help me. I can assure that the immo off solution only in eeprom works for Adi A6 C5 2.5 diesel from 4.1999, with ECU 4B0 907 401H.
Problem solved.
Again thanks
