I wash my 40d myself, always, and use a pressure washer. Have to say now I've used pressure washers for years and am sensible, not pointing the jet straight on or too close to the car.
Anyway, yesterday arfter washing I put it in reverse and get a reverse camera fault come up on the Idrive screen, put it in drive and then back to reverse and all's well ?
So forward to this morning, start the car for work and am met with parking sensor fault, none seem to work when reversing off the drive and then I try to open the front windows and nothing, they won't budge !!
50 yards down the road and all back to normal, even the windows work OK.
Funny things, these BMW's
