Problem:
Cloned a VW Golf 6 EDC17cp14 ECU with Magic Motorsport Flex programmer, did it on bench, written no issues. Everything went well but the car won’t start. Any help?
Solution:
You can’t clone 1-1 because OTP area, need transfer immo data.
You can’t clone this by simply writing the original dump into the donor ECU.
Eeprom has to be adapted to the donor ECU.
How to transfer immo data?
Magic Motorsport offers such service

Services-> [AUTO] VAG MEDC17 Clone
Crypto key for immo data stored in eeprom is stored in otp area. That’s why you can’t just clone. You can do immo off, you can prepare eeprom for new key from otp from new ECU. Or just use MMS way. They make changes in code area to use crypto key that they place in empty area of flash. This way you have clone with all data – even injectors code but you cannot then update ECU.
You should upload your readings (Flash and eeprom data from ori and donor ecus) to mms service vag auto clone. They will transfer immo data for you.
