W212 Auto Trunk Closer problem
This problem also causes the 2 parts of the taillights to misalign by approx 2-3 mm. I did try to adjust the stopper screw and but didn't make any difference. Any idea if this could be easily fixed?

I did some research on the internet and found similar problem on other mercedes models, and it seems to be either related to the pump or sensor.
I did a quick inspection on my car and found some problems around the rear end. See the larger gap between the lower bumper plastic panel and the upper panel near the taillight? It seems like the lower plastic panel was mounted 2 mm too much towards the rear end. See photos below.
Does this seems like something that the dealer could easily fix? So should I live with it? I am afraid that the dealer would mess it up even more, since mercedes could not get it done right at the factory.

That Panel Gap PDF is crazy! I didn't even know that things like that existed.
Curious to see if you can get any this taken care of, as I can imagine a Dealer trying to get out of it, or saying they don't notice it/"it's normal", etc. The trunk should be a cinch, but the bumper alignment could be an issue.
I can probably live with the rear bumper panel, but the trunk gap is killing me. My taillights are not aligned and it is just really difficult to accept that. Every time I see another w212 on the street, I kept checking if the trunks were off too
Does anyone know any easy way to fix the auto trunk closer issue? Like resetting the electronics or something like that?

Are you referring to the auto thunk closer ?
Al the local dealers are the same. They did wash the car, but not as clean as detailing shops.
