Hi, basically the engine temperature gauge takes ages to get up to about 40C then will drop down to zero and then might creep up again. The garage didn't have time to look at it properly but what they did say after plugging it in was that the computer showed 50C but the gauge showed nothing. I put a new sensor in before this and the heater blows warmish air so I'm a bit lost as to what to do. Is there any way of testing the thermostat without taking it out?
I unplugged the sensor whilst the car was running to see if that sensor fed the gauge and I've now ended up with a spanner icon on the dash that won't go away even after disconnecting the battery. Any help appreciated. Gaz.
