Yeah I thought that was the problem. Like I said when I replace the interior/trunk light fuse everything returns to normal. All the errors go away including the PDC not working and the SELFLEVEL SUSP. INACT error. Soo @ first I thought this was the final solution. Until I realized I was wrong. I'll replace the fuse, drive for however long and the problem will be fixed for the whole trip, but as soon as a park the X5 and leave it overnight for some decent amount of time, I come back to my car to find the interior/trunk fuse blown out again and all the errors happen again. The PDC stops working, no interior/truck lights and the SELFLEVEL SUSP. INACT error. What the heck is going on?? I guess I will be seeing the BMW dealer soon. What do you guys think about this. How can the truck/interior fuse be related to all of this and I just dont get it.
