coolant temp warning

[s2driveruk]

Coming home tonight and got the temp warning light come on. Sh*t myself but on getting home and checking coolant was where it should be and oil seemed fine too, no contamination so i guess its a gremlin but any idea's where? I thought the one in the base of the coolant expansion tank but any other pointers would be good.

Cheers

Try pulling the plug off the bottom of the bottle some times the sensors leak and can fill the connector up with gunk and corrosion

I would check that first

top tip cheers Dan. new tank is on order anyway as it's brown as usual so i can't see the fluid level without removing the cap...
