Hey guys, go easy I'm new...

 

Lately my coolant light has been flashing usually when I first  start up the car. It's not low on coolant or even above. Read something on here one time it may be down to the sensor? 

 

I've been thinking of just flushing the whole lot out and putting in fresh coolant. How would I go about this too?

 

Any help would be appreciated  

Not necessary, check the wiring to the header tank by unplugging it and bending a paper clip to short the two pins on the connector, if the warning light problem goes away then just replace the entire coolant header tank complete with sensor, if not then repair the wiring to the connector.

Awesome stuff I'll give that a go! Fitting a cupra splitter to it later so will potch about with it then  

 

Thanks

I have just replaced my expansion tank as I had the same problem, coolant light does not flash on anymore.

 

Replacing the tank should sort the problem. Here is a useful guide for replacing this. http://myquickfix.co.uk/2011/10/skoda-fabia-vrs-temperature-beep-expansion-tank-replacement/ 

Callum, thanks for that mate! Changed the sensor and seems to be going good so far. Will keep this in mind though it decides to play up again
