I've got a 523i SE (E39) 1996 with a handful of quirks.
The Warning light for the right brake/tail light comes on but all the bulbs seem to operate normally.
Secondly, the air bag light is on. Our local dealer was unable to resolve this. They have changed the loom as well.
Thirdly, why does the climate control appear to be doing something even after the key has been removed? I cant seem to de-activate it with the Rest button.
Anyone have any ideas whats going on?
