Sunroof DIY service

[Markssl]

What’s the best thing to lubricant the sunroof tracks? I’ve got a 2011 W212 pan roof.
Mine is really struggling to move. I tried WD40 as per YT vids but it’s no better.
Thanks

WD40 is not a lubricant, it is a penetrating compound and water dispersal agent (WD...)

I believe MB supply a lubricant for roof parts?

3in1 Oil is often good.. or a silicone spray. Then work it back/forwards..

As above, I did find a picture from an old thread with what appears to be a genuine bottle of grease.

See here:

I say ring your local parts dept tomorrow morning.

It’s all working perfectly thanks to that lube I bought. It’s specifically formulated for plastic and metal runners at a Fraction of the cost of the MB stuff!

Tip for you - when you call MB parts to price up - you had better be sitting down.

yep,bought a 20ml bottle of MB rubber dressing(?) for my roof seals - £39!!!!

I remember watching a video on utube some time ago specific about the MB sunroof. The clicking was caused by the plastic gearwheels slipping. This was caused by a rubber o-ring becoming brittle and breaking. Access to the mechanism was via the overhead light. The ring kept the wheels in place. A damaged o-ring allowed the wheels to drop slightly, ergo causing them to slip.
Hope this helps. I remember the video was very informative.

Thanks I'll have a google for the video.

had a quick search, and most problems are stuck roof or blind. Both mine open and closes ok, it's just the roof clicks when opening past halfway.

I'll have a look and see if I can spot it.

Bugger! Can't find it either, sorry.
