Electric folding mirror on E46 330ci sport

[Kettmark]

My passenger side electric folding mirror has decided to stop working. It's stuck in the up position. I can hear the motor in it trying to fold it down when I press the drivers side button and I've tried spraying with WD40 but without any luck.
Anyone had any experience of this with their car?

I believe my e39 uses the same system, in which case gentle encouragement down then going through the cycle again gets it reset. It sounds like it's travelling just past the switching point, I doubt it's actualy seized.

had an oil change done last weekend & was informed by the garage that the motor had packed up in the passenger side mirror.. £200 + VAT + fitting. Anyone suggest where I could get a working 2nd hand one from?
