Well today i was driving and my low coolant warnrning came on turns out the nipple for the hose that feeds the coolant overflow bottle has broken. It should be a simple fix I just wanted to see if someone can give me definite part number so that I can call it in to my Mercedes dealership and get the part ordered. Below I have circled the broken part in red and drawn a yellow line where it snapped (the piece is is a small black nipple with and o-ring on one side and is held in place with a small metal clip.Thanks for the help.

As I mentioned in my little piece above, this should be replaced in all M271 engines as this small part becomes very brittle and breaks. In the interim, take 2 golf tees to stick in to the the leaking parts, 1 in the hose and the other into the plastic nipple, this will get you by until the part is ordered.

The design of this part is very stupid, of course a plastic part becomes weak when it is situated above the exhaust manifold

Does anyone know the name or part number for the locking clip in the picture?
