Hi,

I'm trying to adapt used ECU (from other car) to a Golf 6 GTI (MED17.5). I don't have old ECU or old ECU flash/EEPROM data.

The used ECU I have is from other car and its flash has IMMO OFF and Stage 1 maps inside. My intention is to get it working with IMMO ON and STOCK maps in the car.

What I've done is getting an original flash file from Swiftec database (with IMMO working and stock maps) and read current EEPROM data in the ECU, then I've read the cluster data with FVDI, changed VIN, PIN, MAC... values and write the resulting flash and EEPROM files with KTAG.

When I put the ECU in the car, the immo stops the car few seconds after ignition and ECU generates this DTC:

01 Engine

    System description: 2.0l R4/4V TFSI
    Software number: 5K0907115
    Software version: 0050
    Hardware number: 1K0907115AA
    Serial number: 00000000000000
    Long coding: 0403000C1C070160

    Trouble codes:
        P1570 - Engine Control Module (ECM) disabled


I think it can be due to bad checksum or similar, but I don't know much about this MED17.5 ECUs, so I think can be doing something bad or skipping steps. Can someone check my files and try to help me?


Thanks in advance.

What do you think I can do to solve problem?

I've tried but it seems that this only works for vehicles until 2005-2006
