Title: Temperature light
Post by: Ardz83 on 26 January 2011, 18:25

I have recently had a problem with my dash light flashing at me after 2 miles of driving. The thing is the gauge is fine and the fan cuts in.

Any ideas?

thanks in advance :smiley:

check coolant level, if ok bridge pins on level sensor. if problem solved youi need a new one. if its pre-90 level sensor unscrews, if post 90 need to change whole tank

mine does this. Had new bottle and cap and various new sensors

even tried replacing part of the wiring and it still does it

not every time but usually after a bit of flogging.

Mine did this a couple of times and at first I thought it was due to me putting the key in the ignition and starting the car without waiting for the dash to do its flashy diagnostics and then starting it...

In the end I put in a new sensor... Never done it since..

dont just unplug the sensor, bridge the wires together as well. this will disable the level warning. leavign it unplugged will make the dash think coolant is low

ok this points to wire fault with the level sensor, dash problem, or the dash sensor is bust. unplug the dash temp wire and try it, if light still comes on then its the dash or the wiring for the level sensor.

if its a pre-90, look above the fusebox for a 42 or 43 relay. pull this out and the low level warning system will be completely disabled :)
