What is this whining noise when accelerating. F31 340i
Title says it all, I think.
Noticed this whining noise when driving a bit more "spirited". Recently bought the car from a dealer with 75k km. Got the MPPSK at around 78k km. No other mods to the engine/transmission.
Thought it might be the belt / belt tensioner. But the noise isn't always there.
I don't think the car is supposed to sound like that.
