MotorHoss: Mercedes W204 C300 2008 Rear Sun Roof Drains, Actual visual example. 

2013 C300, rainstorm flooded passenger & rear floor, clogged muck front drains, had to dry carpet foam outside for a week. Couldn't find rear drains after wheel removal, liner removal, plastic floorpan shields. Big thank you, I'm going into the trunk next!

Thanks a lot. I reckon I'll check for same on my 2010 E350. Who knows?

Finally someone talk about the rear sunroof drains Thank you so much 🤍

Were you able to figure out how water entered the boot? I’m having a similar issue. And I just can’t figure it out. Heavy rain shorts the tail light holder and I’ve been through multiple ones already.

How did you clear it?

what about the right sie is it the same?

Thank you

Hw did you open the pipe

So did you check if they were clogged ?

Good info but rather get straight to the point instead of explaining personal feelings. Positive and professional is key at best
