the temp guague in an E30 to go funky? For a while it was registering 'low' on startup until it was warmed for about 10 minutes, then it would go to the center. Recently it has been stuck at the bottom end of the scale (as though the ignition was off) until going to the 1/4 position after a 10 minute run. The inconsistency of it is what gets me.
Also there's been a problem with the power steering- really heavy in one direction until the first turn, then it lightens up. The opposite turn is not a problem. A bit scary when you hit the corners or try for a U-turn
