Well I got my the MB ACC manual. I am trying to read it few pages at a time( Boy I did not study this hard even during my pharmacist exams).
Its all making a little sense so lets see how things go. I still have to get the vacuum tester.

By the way can someone tell me how come MB, famous for its durability, designed such a break prone ACC system. I think they were drunk when they designed this stupid ACC.
Sorry I had to let my frustration out.
