Loose connector at firewall.

Hmmmm....First thing comes to mind is a ground issue... in the instrument panel, behind the cluster or in the fuse box. 19 year old car, even as well engineered as bimmer, that can happen. I am being no help, because I don't a a fix for you. Unless you are a DIY person, shop time. Bob has a good idea there, look at the firewall, under hood behind motor for loose wire(s)

check the conector on the firewall and your earth posts that are on the bulkhead behind the dash and clocks it requires a bit of dissasembly and removal of glove box etc but odds are it is a bad earth/frayed wire to earth causing intermittant fault it took 2 days to trace one on an e30 m3 and it turned out to be a wire where it passed through the bulkhead the grommit had worn and chaffed the loomwhere it passed through it
