Temp gauge has bounced around since I have owened car. Just replaced water pump,and had head pressured tested, car still oveheating. I then checked temp sending unit with ohm meter it sends out jumpie signials, so I replaced it. I am still showing hot.When it goes to hot it goes steady to the mid point and then starts to jumb. I check engine after it gets hot but there is no overflow coming out. I have squeezed hoses to get air out while the heater is on but still does not work. I have not had the radiator cleaned yet, getting ready to do that next. Also checked the thermostat and even took it out to see if that would help. ghead
If I tap my finger on instrument panel the needle jumps back and forth. It almost tells me the gauge could be bad.

Hi, this won't solve your problem, but it is interesting to note and might help. BMW currently has an ongoing Coolant System recall on all E30s from 1987 onwards. The necessary service is free at any BMW dealership, so you should take advantage of this fact and at least get part of your cooling system dealt with.

Just call any BMW service dept., give them your VIN and see if they come up with a recall notice. They replace the defective part, bleed the system, refill it and test again. Who knows, they may even detect your other problem in the process. Of course, don't point out the problem to them. If they find it, they find it.

Best of luck B)

Its most likely your cluster as the temp gauge bouncing around is a common problem on E30's. Mine does it too, but I've been too lazy to pull my insturment cluster out and fix the connection to the temp gauge.

My temp guage on my beautiful 1988 325i doesn't bounce so much as rise gently and worryingly while idling. Once I can get the speed up to about 40 KPH, it starts to cool down to the 1/4 mark. It seems that it runs at around 1/4 - 1/2 mark if I'm moving at an alright clip. Highway speeds usually keep it closer to the 1/4 mark on the temperature guage. I had quite the shock when I was stuck in traffic, with two of the four lanes closed for construction and a nice 20C sunny day and my temp guage is approaching red so very casually...

Ideas? I really don't know much about cars, as this is my first, but I learn quick and thorough!

Also, just for fun, my Oil Service dash light is constantly on, even though I just had it serviced for oil. Is that a reset switch or something more serious. I was told that all my fluids were full, but I think this is when I noticed the temperature problem.

And finally, how about a good resource on fixing the sunroof on my little 325?
Thanks for the any help or suggestions!

What exactly are the problems with the cooling system?

Had an 89 325i, air conditioning always blew very cold until all the sudden it stopped working except when it was on the highest setting. Same for the heater too. During the next couple of weeks, the AC gradually became warmer and warmer feeling air.

What caused this, and what was the solution (car now is sold)?

Thanks
