C180k coupe mystery leak HELP!

[Garymcc1]

Hi all!

I need some help. Recently discovered a fair amount of water in the side compartments in my 04 c180k coupe. I can't for the life of me find where the water is getting in. If I reach isnide the panels that give me access to rear lights etc the inside of the panels are SOAKING as far up as I can reach. Has anyone had this issue or know of anything I can check? Also it's the panoramic sunroof model if that helps but it doesn't seem to be leaking as the water is located only in the rear.

There are usually drain pipes alongside the pillars which get blocked over time and can cause flooding in the rear lights compartment. Either way it will be some blocked drain hole in that area.
