Noticed yesterday driving over the york moors my temp guage slowly went down to nothing, yet still had warm air and plenty of coolant :confused:

Came back up to just below 90 as usual but did it about three more times on the drive home :*


Any suggestions? Im not too worried atm.... Unless you tell me otherwise lol

My old T4 was giving odd temperature indications and one arm of the thermostat was broken, might be worth looking at that.

I just bought a 51plate 1.9td, after a Couple of days the temp gauge was doing as u described and darting up and down. unplugged sensor and cleand contacts, been ok since.
From searching on here from what ive seen could be sensor, connections or even the circuit board solder on the display unit.

Hopefully urs just dodgy connection
