I've had this squeaky / creaky noise in my X3 since the car was only a few months new... replaced windows seal, door seal... etc (do search on my posts), but the noise always come back after a few days... to a point where I gave up and try to ignore it (i know, it's difficult becos the noise is soooo annoying)!

UNTIL 6 weeks ago, I took the car in for an oil service and mentioned the issue again... then they put an ultra-thin-transparant tape on the inner side of the door frames, and the noise is completely gone! It's been 6 weeks now and so far so good (fingers crossed!). I think it says "Anti Rubbing Tape" on the job order form.
