I've tried everything to get it to stop leaking. It leaks right from where the pump fits into the reservoir. I tried siliconing it but then it ends up leaking again. I bought a rubber grommet that fit perfectly into the hole and was snug around the pump nozzle too, still leaks. Does the dealer carry the original grommet? How much is it?

are you sure it's not the pump that's leaking?
they're about $20 from the dealer. worth replacing,
you'll be amazed at the pressure difference.

No, because as soon as I go to fill it it starts to leak out as soon as the water level hits the height of the hole.

Pressure is just fine as well, squirts like a champ.

I second the 1 guy I had the same issue on mine and replaced the grommet and leak sealed it found out it was the pump drooling water down from the back side. And yes the pump workied fine through all the leaking.

Yes, the dealer has the original grommet, it's about $1.

I had that issue on mine, but it was leaking on the headlight pump side.
I found that the bottom of the pump was cracked right at the point that it goes in the hole.

I pulled the pump and bought a solid grommet from the dealer to plug the hole since I'm going to switch to euro lights soon.

It may be the grommet, but don't rule out the pump. Good luck.

In my case I replaced the grommet, which did not help.

Replacing the pump did. Inside the pump is a rubber grommet which seals the motor axle. The rubber was falling apart and the axle was thinner at the point where the rubber touched the axle.

I can not find the bill of the pump, but it was not that expensive.

I got the grommet from mercedes for $2. It's very soft supple rubber that sealed it up good. No more leaks! yay! Thanks for all the input.
