Hello! Any updates? My car just did the same thing yesterday, driving, tried to accelerate after a speed bump and the car completely died, no lights, no hazards, no nothing, just died, car stuck in drive, can´t access battery yet, I´ll remove my back seat today to access, but is not doing anything, I had to tow the car to my house.

from the easiest ones is loose terminal on the battery to more complicated like rotten wire sunder the body if the battery is in the trunk, there was some technical bulletin issued about 3 series - common fault close to rear nearside wheel arch- they were fitting extra sleeve on the power wire.
