Question
A few weeks back, I noticed condensation forming on the inside front windshield. I couldn't figure out why it was happening until I discovered the water leak in my trunk. I found the water after opening the trunk and a blanket on the left side was completely soaked.
Any ideas of where to begin with this problem. Given the expense of BMW service, maybe I could fix this one myself.
Best Answer
If you have a sunroof more than likely the drain hose is clogged, when its not raining open the sunroof and pour a glass or two of water around the rim area of the sunroof it should run out under the car if it dosn't the sunroof drain is clogged.

For many that is the case, on my X3 in particular(also a few people on other blogs have found) the sealing on the windshield, around the sunroof and back windows are very cheap. Not BMW quality! They are actually chipping away. I couldn't find the problem when I was getting water all inside the front and rear seats...then on a heavy rainy night, the rain wet the cluster in the front panel and now the electrical damage has been done. I suggest you check into the sealing and see how yours looks/feels. The seal is an easy fix but not the water damage the to the inside of the vehicle that can potentially be caused!
