    S55 Air Whooshing Noise

    Hi all,

    In my M4 when I’m in M2 mode which is everything in Sport+ and I’m accelerating hard there is what sounds like an air leak under load. It doesn’t happen in normal mode or in M1 (Sport) mode.

    I had something similar on my f30 330d and it was normal so I’m guessing it’s normal but I just wanted to know if anyone else had this?

    No error codes coming up for low boost pressure or anything like that.

    Does feel down on power? I'd check the pipes around the charge cooler.
