My blue coupe has the SLK320 moulding on the pass door. It works fine.
I’ve found a place in Germany that has more than 10 of them, but they won’t send it here due to Covid. No problem though. I’ve got a couple of ideas I’m going to try on it as it’s not super bad. I think I need to adjust the window a bit as I’m getting a little hissing in the front upper corner and that seal at the top is in almost new condition. I just really wanted to avoid taking the panel off but that seems what is going to have to happen. This might help with both problems.
