Hi,
left of the brake booster (#2) and unter the part #1 there is a cavity with several hoses. This evening I poked a vacuum cleaner tube in to suck out the dirt and leaves accumulating there. The vac tube must have touched a hose and some kind of oily liquid leaked out.
In order to check the leak I tried to remove the part #1 ( a plastic cover spreading from the wiper motor housing to the right fender), by removing a screw (#7) and lifting the clips 4, 5 and 6 but without success.
My questions:
1) what are the hoses there, transporting what liquid?
2) how can part #1 be removed (I already broke clip #6

)?
I'd appreciate your help, don't want to drive tomorrow to work with this leak.
Thanks!
My car is a 1996 E320 as in my profile.
