W211 cup holder wooden cover opening issues
 

So that cover doesnt glide smoothly like ashtray cover is. Just slams into place loudly. How to fix this issue? Thanks

There's a dampener in the linkage that has become disengaged. Taking things apart will show you what's up.
Someday I'll do that with my glove box; it quit opening softly a year or so ago.

if you are referring to the center console wooden slats that slide back revealing a cup holder (not the butterfly doors) it might be that in the past something was spilled on to it like soda or anything really that would cause unprotected wood to expand. the same thing happened to me and i had to disassemble the center console and to get to the wooden insert. once you do this (there are tutorials) you will notice that the piece that slides back is positioned within two grooves and the wood that slides within those grooves is bare wood so any liquid would cause this to slightly bulge enough over time to the point where it becomes to big to slide within said grooves. this is more true with things like soda etc. anyway once you disassemble it take some sandpaper to the untreated bare wood sides of the wooden slats and reassemble and it will glide back like it used to. i am pretty sure if i understood you correctly, that this is your problem.

Cover my not be engaging correctly see attached bulletin for a better understanding concerning removal. Fine, check mechanism by removing assembly. Replacement part # is 2116800350 if need be.

Just soak it with wd40 in the hinges of the arms. Will be like new

It opens i mean. But very hard slamming. What i need to disaasemble to get to those hinges?

Unfasten (no need to remove) gear shift cover to expose two screws.
