1 Answers
The reasons for sunroof leakage in the BMW 3 Series are as follows: The causes of sunroof leakage may include: Small sand particles or dust blocking the sunroof drainage channel, or the sunroof sealing strip being displaced or "lifted." Location of the sunroof drainage hole: The sunroof drainage hole is located near the A-pillar at the front of the sunroof. To locate the drainage hole, you need to open the sunroof. There is a tube inside the drainage hole, which runs through the A-pillar, allowing water from the sunroof to flow to the bottom of the car. If the sunroof drainage hole is blocked, it can lead to sunroof leakage.
