Well, not today, but things I've done recently (2006 X5 3.0i, manual 6 speed trans, 82k):

1. Listened to my wife complain about not being able to use the driver's heated seat (because the element is just about ready to burn a hole through the leather and I haven't fixed it yet).

2. Listened to my wife complain about the passenger side door mirror that doesn't want to stay in place (because something is busted inside and I haven't fixed it yet).

3. Cleaned driver's side door latch assembly / Hall effects sensors because interior lights would come on intermittently and drain the battery. This I fixed!

4. Cleaned up rear light electrical panel corrosion that was causing rear brake light to not work. Fixed!

5. CCV system replacement.

6. Power steering hose replacement.

7. Oil change.

Soon will be: front brakes, belts, and tires.

Every time I check something off the list, something NEW pops up! We considered getting rid of it, but A) no one really offers a 6 spd manual and we love it, B) nothing seems to ride / feel as tight as the E53, and C) new vehicles are expensive!
