Hello all all - hoping someone can help...
.
My sunroof opens fully and smoothly however when I attempt to close it it stops about 4 inches from full closure and reverses back to fully open.
I have performed the 'Re-set' procedure in the handbook about a dozen times to no avail except the 'final' (?) step which involves temporarily removing the sunroof fuse from the main fuse box behind the cover at the end side of the dashboard. I understand that step is suggested whenever the battery has been disconnected/replaced and believe that my battery was replaced not long before I bought the car. Because I don't want to pull fuses if there is something I've missed in the standard re-set procedure any additional procedural advice would be appreciated.

Thank you

 

Try cleaning/lubricating.

 

Thank you for your reply. Since my original post I have done that (Clean/Lubricate) however it has made no difference.

 

Clean, lubricated, no restrictions: perform reset at least 3 times in succession no success. If this fails try summer opening/closing to see if it clears. Fails, worst case scenario motor gear may be wearing just enough to cause closing malfunction if this is the case gear is available separately (MB does not offer this) search ebay. Remove OCP to access.






Lastly, if gear/motor seems fine find an independent to clear/reset using Xentry (MB diagnostics).

 

Thank you for you detailed and informative reply. Due to the weather and other issues I wont be able to get back to my CLS for a few days but when I do I will follow your further advice and confirm eventual outcome.

Regards

 

Exact the same thing happen to me. Can I close the sunroof manually like W211 ?

From this video, W211 can manually close the roof by using Allen wrench. Is the CLS the same ?
