Problem:
Trying to clone a Audi Bosch EDC17C74 ECU with foxflash, but failed.
Error “OTP sector not writeable”.
Solution:
You cannot 1:1 clone vag edc17, there are otp sectors.
EDC17C74 is not possible to clone with any tool, because this ecu is immo VI generation. Immo VI gen you must adapt on car. You can do only immo off.
Just do immo off on the new ecu and ready to go, can’t make clone on these due to otp sectors.
