Smile Need Help With Coolant Temperature Gauge

I have a 1995 BMW 325i. Its coolant temperature gauge shows intermittent problem. Most of the time it works normal. Some times it drops completely, and bounce back and forth. It clearly indicates some faulty contact between the sensor and the gauge. I need some advice about how to proceed to detect the faulty contact. For example, where to look? And how to check? Many thanks in advance.

Did some research on the subject. Re-insert the fuse 31 and touched a little bit on the socket of the coolant sensor. The tempaerature gauge has been stable for 3 days. Do not know if it is just sheer luck or coincident.

In your case, it sounds like you could have a sticking thermostat. I'd change that when I did the flush.

For the car thats spiking. You may have a waterpump problem. You may want to check the seals on the unit. Loosing coolant or any smell of the coolant is a good indicator. To check it, take off the fan and belt. Wiggle the shaft and if it clicks up and down, thats your problem. Just a thought.

Thans for all the replies. It has been 2 months from my first post for help. The problem is still there. But I have been actively read other posts in the forum and patiently observe my car to see if I can find any clues. So far I have found interesting patterns for my temperatrue guage problem.
1. The temperature gauge will start erratic behavior only after the car is really warmed up. Usualy a 20+ miles highway drive will do it.
2. When the erratic hehavior starts, it drops all the way to 0. Sometimes bounce back to the middle. But most of the time stays at 0.
3. When the problem begins, the temperature needle starts unstable. It moves up (not beyond middle) and down a little bit the same rythem with lef/right turn signal. The emergency light button will affects it too. Even the trip reset push button will affect it. At one occasion, It was down to 0 already. I pushed the trip reset button, the needle will swing back to middle again. When I release the trip reset button, it drops to 0 again. It is repeatable. It seems any electric button can change the temperatrue guage needle mood.
4. I have read other post memtioning water problem. I have been keep my car from any water for 2 months. Is it long enough to eliminate the water problem?

OK. just thought to post it again with my observation. Anybody experience the same? Still puzzling!
