Hi,

I own a 2012 F31 330d. I have the "weirdest" issue - the doors are "sticky", meaning that they require more force than expected to open and close - i.e. the hinges are sticking.

I've tried with lithium grease without any real effect. Might be because lithium grease is missing the penetrating effect necessary to loosen up the hinge action. I really want to try the BMW recommended product. From their catalog it might seem like 83 19 2 208 609 or 81 22 9 407 711 could be the product to go for.

Anyone in here who knows what the correct product would be?
