I refilled my fluid yesterday and its already gone. Anyone else have this same problem with their w215? If so where, did it leak from a grommet, hose, oring, or even cracked reservoir? Any input is appreciated.

Yes, I have the drips too It is a small hose that connects to a small pump or relay near the headlight on my car. This hose and pump are on the front lower part of the water resevior.. Do a search, A former post shows to cut a small 1/8 x 1.5 hose to fix this.. Either that, or buy the whole line from dealer for 90.00 plus $..

Just found the link to a possible simple fix..https://mbworld.org/forums/showthrea...her+fluid+leak




I am going to try the hose trick this week.

Ps, the hose is not broken,, it just does not fit as snug after it ages..

I had a cracked reservoir on an S55 once.

I bought a foot of small ID rubber hose but could not make it fit.. I used 5/32 and it was to small.. I then decided to use some silicone around the male side of the plug and then plug the connection back together. Waited a few hours, filled the bottle up and no leaks so far..

I did have to pull the pump out of the water bottle to put silicone on the end of the male fitting. The small pump just press fits into a rubber gromet.. Just pull up and comes right out..
