Had a moment this morning, got ten miles down the road, noticed the temp hadnt risen at all, so my first thought was thermostat, but the heater was strong so thought maybe not.
Then I looked back at the gauge and it was at normal. On my way home it again dropped to zero from lukewarm, then I actually saw it spring to life, so I discounted the thermostat and figured its a connection somewhere, so I fiddled with the sensor and it was fine all day.
Then tonight, yet again the gauge refused to lift off zero. I gave the top of the dashboard a gentle clout and it sprang to life, so Im presuming the issue is at the dashboard end.
My question is, would it likely be a niggle in the gauge itself or just the connection to it, given the 'fix' I made. I thinking as the car stood a while, it could have got damp in the car in that time possibly.
