We got our M3 LR about 2 weeks ago. Whenever we accelerate you can hear a fan ramp up with the acceleration and when we come to a stop, it often runs for a seconds after coming to a stop. While sitting still no fan. There is no A/C or heating fan on.
I assume it is some sort of cooling fan for the drivetrain. On my Y it was never audible. On my S, not audible either. The temps are not high either outside. Maybe 40-70F was the range. Outside the fan is pretty loud, inside it is about the same as the ventilation fan on about 3. Speaking of which the ventilation fan on the 3 is FAR louder than the Y at higher speed levels.
I can only imaging how much the drivetrain fan will run when the temps are 90-100F. On the Y in these temps, even towing a trailer, it was very quiet. The loudest fan was the interior fan at speed 5, 6 or 7.
Anyone else have this issue?
