Hi. I hope there is someone really clever who can help: sunroof of (or something else) A160 2010 leaking inside on the left front pillar. Been to garage twice - checked it myself but cant find the reason. It only leaks in when car is not level and leaning forward (our street). Lowered the ceiling trim but the sunroof drains look dry and fine. Pouring buckets of water on sunroof and directly to the gutters come out fine behind the wheel arch. Im puzzled. I wonder if its trickeling slowly overnight somewhere.. accumulating so that in the morning the pillar is soaking wet. The wet area starts from the hold bar on top of passenger door all the way down the pillar to the little speaker next to windscreen. Anyone ideas...? Please. I cant keep parking my car always the same direction (its fine pointing uphill) Thanks!!!!!
