Buzzing in the gauges above 70 mph
three weeks ago I got a 2011 E90 M3. It's been great so far (still only at 750 miles though ;-), but since the day one I have one problem. When I reach a certain speed (somewhere between 60 and 80 mph) I get a loud buzzing noise coming from the dashboard at the driver's size. It sounds like it comes from behind the gauges.
It doesn't depend on the road quality, gear and touching/holding any parts of the dashboard makes no difference.
Any idea what might be going on?
