My temp gauge is malfunctioning goes right hot without starting the car?

Asked by Sep 21, 2016 at 09:09 PM about the 2001 BMW 3 Series 325Ci Convertible RWD

Question type: Maintenance & Repair

The other day I noticed my temp gage started to lean to the red (hot) which it has never done before, but a little while later it was right back dead-center as usual. This morning I started out and in less than a mile the needle was already moving into the red. I was right at an Advanced Auto so I went in and got a quart of the BMW recommended Blue anti-freeze, but when I opened it up A.) it wasn’t overheated, and B.) it only took a quarter to little less ½, the red stick indicated it was at an acceptable low-minimum, I went right back home.  The car has been in my garage for the past 8 hrs. I just went out to check it out, turned the key to the 2nd position (not starting it) and the temp gage needle shot right to beyond hot while the red (hot) marker actually lite up red (never knew it did that) … Is there a sensor or something that I can check … or could it be the actual gage itself? When it happened earlier I thought it may be my thermostat, because while I was on my way home (this morning) I put the heat on (just in case), but it didn’t feel like it was throwing any heat? …. This car has run impeccably well without incident for the past 4 years …. HELP!!!!!

You may have to get a diagnostic check done on it. Not sure what the cost on it would be. I own an Envoy and for the diagnostic check it cost me 145.00 . Or you can find out if it is the Thermostat and just change that to see if it makes a difference. Good luck
