See my post above for some pictures. You'd probably be better off finding it in either a junk yard or messaging someone on eBay seeing if they will sell you the bolt/grommet... Above it was mentioned a 8mm bolt was used but, Ideally I would want the oem bolt/grommet.

I am adding the trunk power close module to my 05 w211 and have the same problem. Looking at the photos, the screw appears to be a custom shoulder bolt with a rubber bushing. Can't believe MB wouldn't sell this in service as it is a wear point. If I can't buy a replacement from MB my plan is to use nylon sleeves/washers and a shoulder bolt. Fortunately the attachment point is not visible after installation.

Well after months of collecting bits and pieces together and finishing up a project at work, I set about installing my trunk closer.
I have attached a PDF of how to install the trunk closer on W211. This was one of the more challenging retrofits I had to do simply because there wasn't much documented in the WIS and I purchased some used parts and the harness they sent was completely wrong so that had me confused for a while.
This can also serve as a harness replacement guide for those that already have the closer and had issues with their harness getting cut. By the way, I have a spare harness (somehow, I ordered two) if anyone else wants to attempt this.
Had to break it down into 4 pdfs due to file size limitations. It probably messed up the numbering also for the steps ..

In any event, I installed the system this weekend and it is working great. I never could have done it without your efforts.

Although I took all my parts from a parts car I have, I wanted to thank you for making this post. Got me through it very quickly and I luckily didnt even have to have my car programmed for the power trunk. Once I plugged everything in it started working.
