Just got home from work and i had the same thing. Not quite a snow storm but makes it look like i have a bad dandruff problem. With other recent issues with my car the least i can say is i am pretty damn pissed off at the moment.
Need to check how much this is going to cost but £800 job is the last thing i need right now. Makes me think about just selling and buying something other than bmw.
Edit: I am having issues with the speed of my blower fluctuating as i have posted in another thread. Anyone think these issues could be relaed or just coincidence?
