CEM decode, TFT retrofit & dealership computer

[Gir]

Does performing the CEM decode and TFT retrofit cause issues with hooking up the car to Volvo dealership computers? I searched the forum for this question, I swore I read somewhere at some point it may cause issues. Thanks

@Gir known issues are listed at the end of this guide.
And you need to use a DIM with white back cover and from a donor car with automatic transmission. DIMs with black back cover (from cars with VEA engine) won't work in your car.
