Well, have problems with my Q4 (which I own only one month, it's my third Alfa - 33 1.7 16V and 145 1.6 TS) and wanna ask for help..
The right sunroof drain tube seems to be blocked. Everytime it rains I have a swimming pool in my car at the passenger side (right side). The water is leaking through the black plastic cover between sunroof and the door. Does anyone have experience with cleaning,unblocking drain tubes? Where exactly does the drain tube lead, where it ends?
