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.
