BMW & Alpina Replacement DME 8.4.1 (B48)

The MG1 is the new familly of ECU used in most BMW.

The model is too new for common failure trends to emerge yet.
We have replaced them for failed canbus output as well as damaged sensor inputs.
The MG1 can get bricked after some tuning attempts or damaged by boosting incorrectly a car.

As always, Bimmerpro is the first in Canada to be able to replace these BMW control units with refurbished units.
