Subject: E30--jumpy temp guage

Jason asked about a jumpy E30 temp guage

There is a common E30 problem with the clamp that holds the temperature gauge to the back of the SI board coming loose wiht poor/intermittent contact and causing the temperature guage to jump. Remove the panel inspect and tighten up the clamp. There's a 90% chance that will cure your problem. I seem to recall some people adding a wired connection in parallel.I never dis, and my one-time tightening lasted another 100K miles.
