False coolant overheating warning light/sound & temp gauge rise

Featured Replies

Hi. I'm new to the forum so please bear with me.

I've got a weird problem with my daughters Fabia. For no apparent reason the temperature gauge will suddenly go from normal to max even though the engine is not overheating. At the same time both the red thermometer symbol and audible warning come on. Everything returns to normal when the engine is switched off and re-started. Our local garage haven't got a clue and have suggested we sell it and buy another car; not very helpful as we only bought it in July! Any suggestions as to what may be causing it?

Hi Mark,

If you post this in the correct mk fabia section youll get a better response -

This sub forum is for difficulties with the briskoda forum, rather than vehicle issues :)

(Dont worry youre not the first nor the last to end up in the wrong place)

As an aside, that sounds like the Coolant Temp Sensor is knavkered, or... if its an older furby, it may have some dried out solder joimts on the MCB of the dash causing issues.
