I'm the original owner of a 2005 Z4 2.5. I've been delighted with the car. 52K miles.
Last week I foolishly left the top down in the rain. My battery light has been on for a long time but it has not failed and I don't think there is an alternator problem. However I now have the following problems:
1. The directional signal indicator lights do not work. The themselves lights do.
2. The driver side air bag light is on.
3. The mileage and info panel comes on bright anf then dims. Same for the radio panel.
4. The top works until #3 happens. Then it does not work.
Do you all think that I have a single source problem or multiple problems ??
