528i F-10: one rear window opens when parked unoccupied
Our 2011 528i's right rear window opens on its own when unoccupied. This occurs every week or two, sometimes longer, and generally the window opens about 1 1/2" and stops. Several times it has fully opened. Naturally, when the car is at the dealer for warranty servicing, the fault, so far, has not occured. The dealer has "re-programmed" the control unit for windows and says that unless the problem will replicate in the shop, they don't know how to remedy the problem. Any ideas on how to catch the ghost that is causing this? The car has been great. This is the only problem, and it is unnerving because the car cannot be comfortably left in the city.
