With me it always drips from the IR receiver if the car has been standing longer in the rain. If you take off the panel with the IR receiver and the inner lamp above, you can see after a rain that there is everything wet and wet. The water then runs down on the inside of the A-pillars and drips over the pedals one on the foot. One can not see anywhere where the water comes from, only that it comes from the highest point of the roof under the IR-. Theoretically, it could come from the antenna, but it is too well screwed and not at the highest point. At least it doesn’t come from the sliding roof. Did someone have the problem already and know where it actually comes from? Is a Megane 1.6i Bj 04.1997
