I heard a while ago about a safety feature on BMW`s that the front door windows will open when submerged in water, is this true ?.
recently my windows have opened twice, the first time was after a very heavy rain and the windows opened to half way. The second time was last weekend, we went for a run to Windermere, it was quite a nice day but when we got back to the car park and got into the car the windows were open about 10mm.
Any suggestions. I have a 58 plate 530D M sport
