it is a 1997 c200,-there appears to be a puddle of water under my car which i noticed this morning,which here in england is a fine spring day.

further investigation reveals there a slow leak from the screen wash bottle-there is what appears to be a small black grommett/seal in the front lower end of the bottle,where the leak is-if i plug the seal with my finger,the water stops leaking-the bottle is now nearly empty-

anyone come across this problem before,is it just a case of replacing this black rubber object for the dealer?
