Last week my stereo decided to go mute. It was strange, it all seemed operational but no sound, even the car's warnings muted (like seat-belt and PDC). Since the volume button does not actually turn the system off, I even turned off/on the whole car (it's like a sick PC joke...) No luck.
The next day it was on again.
And then yesterday did it again, so I called the local BMW service.
I scheduled an appointment for this thursday.
I'll keep you posted...
BTW I examined the car hood's smoothness around the front door mirror area more closely. The lines between bonnet, fender, and door are not really very smooth. The differences in height can be detected by hand even visually.(say 2-3 mm at least)
No wonder we have so much wind noise...
If this is the regular BMW quality, this might be my last Bimmer
