I seem to have a leak on my TC. It happens occasionally, usually when the car is parked nose down or when I'm driving and turn sharply. The water seems to leak down from where the roof liner meets the top of the windshield. It leaks onto the rearview mirror, then drips down onto the radio and touchscreen. I've heard it could be the windshield seal, the antenna seal, or leaks from the stock roof rails. Has anyone experienced this before? I just want a starting point before I take it in to get fixed at the dealership.
Also, the water feels very slightly oily, which seems odd to me.
