Huge fan of the site. I recently purchased a 1990 red bmw e30 convertible. Great car. I read on the site how to properly change the oil and how to reset the oil lights. I followed the directions and have green lights on my dash for the oil. However, the problem i'm having now is that the water temp gauge is on high. With the car off the gauge will be on low but in the second key position it goes to high, prior to the engine even starting. If you BMW geniuses can give me an idea of where to start troubleshooting the issue that'd be great.
Thanks Tim, I wasn't sure which it was.
