Just bought a 93 E34 M5. Has been in garage for about 2 weeks due to MI snow but finally had 50 degree weather so took her out today. While driving, the temp guage workes great and once it hits mid point, stays there. However, I hit a patch of road of potholes and while navigating through there, I noticed that the temp gauge has dropped to zero (all the way to the left). I hit the dash board and the temp guage jumps back to mid range. I hit another rut in the road, and the temp gauge goes al lthe way to the left again... what gives? Any Ideas? thoughts? Car has about 160K miles. Prior to arrival in MI, it had been a CA car for the past 6-7yrs.
Thanks.
Thanks.
