Hi Guys,
I recently noticed this weird noise when driving the car at low speed and revving up the engine a little bit. Its this weird rasping or buzzing noise that i thought was coming from the boot but turns out its coming from the outside of the car, maybe the exhaust? i filmed it both from inside the car with the boot open and from outside the car too.
im taking it in to BMW next week but do any of you guys have any ideas as to what it could be?
