I had the same thing happen...in just one rain storm and it has never done it again. If they are still full open them and shake the door back and forth. Mine had some dirt or something blocking the holes on the bottom of the door that lets the water pass through the door...so when I started shaking it (opening and closing) quickly it dislodged whatever was clogging the holes and like I said it hasn't done it again. Good luck!
Is your M3 an HPF? I am seriously thinking about purchasing an 05 or 06 m3 and putting an HPF on it and just wanted to see how you liked yours... AMG Eater is a great name! haha (I am a huge Bimmer guy)
Mine happens every time, I will check for dirt in the bottom of the door as shaking it out works every time. My issue is I am putting very expensive speakers in the doors and don't want them getting ruined so I need to get to the bottom of why its getting in there in the first place...
Yes my M3 was HPF (and is there right now). I just had them remove the kit from my car (to sell it), however if you are interested, you can buy it before it leaves and have the stage 2 kit re installed! Its an 06 M3 coupe with competition package, 6 speeed manual, white/black, NO SUNROOF, etc., etc. Great car. PM me for more details...
Do a search on this and you'll see my post about it. The dealer will replace some seals if you take it in.
My truck isnt' under warranty anymore, do you by chance know which seals they are so I can purchase and replace them myself?
Thanks guys,
