I have a 2019 M3 MR with approx 4500 miles.
On Sat Feb 21 2021 I got in the car and put in my pin and got warnings that the Brake Regeneration was not workng and the AutoPilot was not working and the Cruise Control was not working.
It was right.
I was going from E. Mesa to Sun City.
Eventually the braking began working and the cruise but the Auto Pilot never did kick in.
At one point the car lurched as though someone had taken their foot of the gas but I hadn't. There was a car on each side of me but nothing in front or back of me for hundreds of yards.
I have repeatedly had problems with these warnings and things not working.
I think I have a 2.5 MCU. I am wondering if it is defective. is there any way to tell for sure?
It seems I have read of some place that fixes the MCU's for a reasonable price but don't remember where. Mine < should > be under warranty I would think.
