Hi all.
I have a leakage, i guess it's from the headlight washer pump. Please, tell me how should I remove it (is it the pump ?) to repair the hose connector. The car is s500l '05 with abc

Maybe this will help:

I had a leak from my washer tank and fixed it about two weeks ago. My car has two pumps as it runs windshield washer and headlight washer pumps from the same tank.

My problem was the leak in the connection between the headlight washer pump and the tank. This connection is a rubber grommet that you install in the tank and then push the pump thru it and the grommet seals the pump. Both pumps install the same way.

If you have a hose leak go get the grommets for the pumps as you will be taking the pump(s) off the tank and it is easy to replace those grommets at the same time. Over time they wear out from vibration and start leak.

Thanks for the answers. To be sure what I need to change I have to remove the pump on the photo. If anyone knows how to remove it, please let me know. Thanks

I have a similar leak. the leak is worse in the winter. I can't keep my washer fluid tank filled to the top. Ironically, my BMW has the same type of leak.

Pull. It just pushes into the rubber grommet. My parts catalog shows:

A1239973681 - Grommet for windshield washer pump
A2218690121 - Windshield washer pump

You can pay $25-30 for the pump from Mercedes, or under $10 for an identical part from FCP Euro. I've had the $10 pump in for a year with no issues. It's a common part used by several German auto manufacturers. Oh, and when you take that pump out, have a large bucket underneath to catch the gallon or so of washer fluid that's going to gush out. I used a coffee filter to strain it and pour it back in after I was done.

Thanks for the help will try to pull it. My tank is empty as a part of pump is already broken also, I have noticed an electrical line or smth kinda that inside of the hose. Guessing it may be smth like heating line. Also, read somewhere that this parts for cars with ABC are a bit other.

Yes, the lines are electrically heated. Reservoirs for ABC equipped cars are different than non-ABC, but the pumps and grommets are the same. Those are the part numbers I used on mine, whcih does have ABC.

Really happy to hear that you also have abc your further help will be much appreciated will try to solve my issue and get back. Thanks again
