Some info: today I took my car to the dealer for them to have a look at this issue. They gave me a loaner 1 series hatchback model (doesn't have frameless front windows)... Well you should have heard wind noise in that car - it was like 10 times worse. As I suspected they said that everything is within spec and if they would try to "calibrate" the angle of windows then this would probably result in water leaks. I tried to lubricate seals with some glicerine which (at least) keeps rubber look "more fresh" - and maybe this also reduced a noise for just a tiny bit as well (mind you it could also be just a placebo :biggrin
. If someone has some other suggestions, don't keep them to yourself and let us other 1 addicts know. Just thinking...maybe the solution would be to add another very thin layer of rubber to existing seal.
Good day to you all :smile:
