temp sensor temp gauge

ok got that. is there any way of testing the connection?

ie the trick to get the gauge needle to move? theres 4 wires. this would elimate if the sensor was faulty or not

You can do a binnacle test, Hold down the mileage reset button with the ignition off, turn the ignition key to position 1, Wait for TEST to appear and then release reset button, watch as the binnacle does a self test.

As for sensor it can be checked with a multimeter set on ohms.

25.C is 2050 - 2470
80.C is 261 - 306

ok changed the sensor still a no go. been through and check all the connection as much as possible. it has to be something around the engine config as im suffering with the tach not working and the avg fuel gauge under thats not working.

checked the fuses there all ok.

so any ideas now

Did you try the binnacle test?

The wires for the sender should be brown/yellow and brown/violet. Short them together briefly and if the wiring is OK the gauge should go up.

I think the wiring for this goes through a connector beside the brake fluid cylinder and diagnostic socket in the engine bay.

I have exactly the same problem on my 1996 320i. I can't find the thread that tells you how to reset the computer by pulling the fuses. Can you remember where that was? Thanks.
