Temperature Gauge

[toastyhamster]

All,

 

My temp gauge has stopped working. Well nearly. Just donw around 300 motorway miles and on the return journey the temp gauge went off, then occasionally we saw the bottom bar light up. No problems getting home, and there's plenty of coolant in the header tank - top of the radiator is hot, but bottom is only luke warm to touch. In car heater works - but doesn't seem that hot when I put it on max.

 

Any idea what could cause this? Water pump?

 

Engine didn't smell like it was overheating, although since I got it back from it's repair I've noticed a slight burning smell from the rear of the car - I'd assumed this was overspray on the exhaust or something similar - but maybe not.

 

Anything I can test to prove or disprove?

Thanks

What repair? Has the radiator been out or emptied?

New rear offside wing and rear suspension, nothing forward of the doors.

Exhaust smell is as you say, overspray. But that should quickly burn off and the smell disappear. Might be worth having the thermostat checked. It could be stuck open.

I agree. Did 200 motorway miles today and I only saw the first line on the gauge light up briefly when I put my foot down on the way home this evening. Radiator is still cold at the bottom and heater only really gets hot after 50 or so miles, and even then it's not what it was.

 

 

Booked in on 10th for this and hopefully the ESG recall if they can get the parts.

Dodgy temp gauge sender unit, has been a known problem and can cause car to think it is overheating and go into limp home mode.
