Passat B5 1.8 AGR
Manual gearbox
ECU: 8D0 906 018R
Current Soft. Coding: 04001
DTC: 18020 - Engine Control Module Incorrectly Coded
Hi Team,
I have problem with Passat B5 after replace ECU.
Previous ECU dead and car doesn't work. I have new, the same ECU without IMMO.
The car starts, but I have the error as above.
I can't comunication with orginal ECU so I can't read correct Soft. Coding.
VCSD does not suggest an coding method.
Can anyone help with correct coding and a login to change the coding?
Thanks in advance.

Hi,
EEPROM what I found is ST950403. It is correct?
Unfortunately I have no posibility to read.
I wonder if resoldering these memories will solve the problem.You can't treat a car like a human being. A car requires love.

Hi,
I think we misunderstood each other.
I do not have a programmer to read this EEPROM model.
I asked if resoldering this memory to the new ECU could solve the problem.You can't treat a car like a human being. A car requires love.
