Hi guys, I have been busy today taking my door cards of to chase speaker cable wiring and to sound proof the doors. Once I got the door cards off I could see that somebody careless has already been here , the foam membrane is damaged and missing on one side . I'm looking at replacing it. I have been told that it is £40 a side from BMW. I have seen 3M foam or some sound proofing foam, I know it needs to be waterproof. Has anyone else done this?. I wish people would be careful when doing work on cars half off the door poppers are broken and the trim on both door handles the clips are damaged . I know when you get a car second hand that you expect ware and tare but when you find bits damaged through neglect it's annoying.
