    My car reaches operating temp but when I turn on my heat I only get hot air from the top vents and footwell vents, the middle vents blow cold air. My defroster works as well and the stratification dial is set to red. Anybody got any idea on what to test or fix? Thanks in advanced.

    I have a 2003 325i and my sunroof is leaking through the passenger mirror light and down the front pillar. I have tried resetting it but it didn't help. What can I do? It also appears that the back of the sunroof is slightly lower and isn't flushed with the roof.

    Bought my first car 2 Weeks ago. It is a 318Ci with N42 engine. The problems started the first day. My current problem is that the car feels like it has 30 HP less then it should. It builds RPM, doesn't stutter, and has great gas response, but just doesn't go. It is my first N42 and I don't know...
