Leaking sunroof

[Inderpal]

Hello people

Need some advice I have a 2009 mercedes clc c200. The vehicle has a panoramic sunroof and I have noticed that the blank sunroof blind has wet patches along the edge.

I can't see any signs of water coming through just the blind has wet patches could this just be condensation or a leak?

Hello and welcome

It will be a leak... open the sunroof and clean and polish the surround then check and clean out the drains.
The polish means that water doesn’t sit around and get where it shouldn’t and cleaning the drains means the water can get away.

Thanks for the reply! Where would the drains be located and how would I clean them

I found the problem the right drain doesn't drain the water out properly. How can I clean it as its a nightmare to get to as there is a glass flap on top!

Would a length of net curtain wire do the job?
Also often the issue is the drain being blocked at the bottom where it exits - usually around or behind the wheel arch area.
