Ringing Noise
 

M3 here... Got a ringing noise on the right side of the dash board... any ideas what could that be?

and other one thing that disturbs me is when I accelerate I hear silencened whistling noise (something with air intake or something?) all I know there wasnt such noise at 2000-3000 miles... and began to whistle at some 3500-5000miles.. any ideas or should I go to the dealer... again? :(

I get that whistling noise in my P5, too. Would love to know what that is. I am not accustomed to such power-driven engines so I thought it was something from that. Maybe not?

Been at dealer tonight... booked a diagnostics on monday.
They told me this: Ringing noise is most likely a result of alarm installation.. some parts may be badly fixed etc.

and the engine whistling most likely is a "generator problem"

that's at the first glance... but will be known on monday :cookoo:
