Water leak

[Tapper21]

I'm sure there's been a few of these posts as I've read a few but looking to see if there any updates.

I've got a 2011 W164. I've noticed some water in the rear back corners. There is No water in where the spare wheel is kept.

Water seems to track off the roof around the rear lights and then somehow get into the rear corners. I've looked and ran the hose pipe. I can see the water come in but it's right down in the corner so not sure how it's getting there. Any advice?

If it was the rear light gaskets surly you would see this around the light inside?

Hi, did you resolve this problem?
I have a similar problem
Thanks

No not resolved. I've had the rear break light replaced because that leaked but unfortunately still leaking. I'm waiting for it to rain so I can put some tape around the car. I'm going to tape the fuel filler cap and bumper joins and go from there.

A few ideas in this thread in case you have not seen it:

W219 CLS55 boot/trunk leak? | Interior

Hi all, When changing my battery recently I noticed a small amount of water (enough to form a little puddle) in the boot floor. Only the lowest carpet was wet, the one that makes contact with the bare metal/plastic of the floor. I think it has just developed as I did check for leaks when buying...
