My Z3 has now been out of action for over a month while first the lateral acceleration sensor was replaced, then while I stripped the interior to try and dry it out, and now while I try to prevent the rain getting in again.
I have successfully sealed the rubber plug at the top of the screen post, and have made a new waterproof membrane for the door, which was sorely needed.
But I just can't prevent rain from coming in along the front edge of the quarter window. The rubber down the screen seems to be in excellent condition and I have treated it with Gummi Pflege as recommended here. The triangular glass presses on the seal in two places as shown on my photos. The rain gets past the first outer seal even though the glass is definitely pressing on it, but obviously not hard enough. From there the water tracks down and runs down the inner front edge of the door, spills over the bottom rubber, down the inner sill and forms a puddle on the floor.
I have no clue what to do. I have tried adjusting the angle of the glass so that it presses more firmly on the screen rubber and it is now at the maximum position. Still the water comes in. I can't put the interior back together again because the whole wretched scenario will just repeat and the foam underlay will become saturated eventually causing failure of the sensors.
I can't be the only person who has had this problem. It has completely ruined my enjoyment of this otherwise great car. Please help me fix it. I'm desperate!
