hi. I managed to find the water leakage. I took a closer look and the water comes in from the driverside windows. There is some rubber seal which is not perfectly aligned. So even when it rains it drips down into the trunk. The rubber piece is between back window and front window. I am trying to push it into original position without any luck. So, any hints on what to do? The seal is on the inside. Like a rubber piece hanging down a bit. Shall I go bananas with a silicone gun? Take it to a glass repair dealer?
