for this car the problem is fixed by changing FEM and programming a new KEY ,
but also yesterday same problem , what i did when i got the car ( 2016 MINI Cooper with BDC ) i update the BDC in Car before i do any thing , then i was trying to reset KM on Bench and i got same error as the FEM from Last week , but i was able tor restore after trying couple of time so the Job was done at the end , any suggestion i still have the defective FEM from last week
