Blue temperature gauge comes on when starting from cold.

 

Coolant level is fine and doesn't happen when restarting after a run out.

 

Any ideas please folks, only had it a week.

Presuming it's the same as my Mum's Jazz, that just means that the engine is cold (which it is) so don't rev the, ah, spheres off it.

Welcome.

As @KenONeill says.  All well with the engine not up to temp 'Blue light',

which is there because no Coolant Temp Gauge.

Yeah, blue when first started, going off when warmed up THEN, if driven hard or without enough coolest, etc, red will indicate overheating!

 

Basically, it does exactly what it says on the tin... Tells you the temperature of the coolant!

The Fabia has a basic coolant gauge, showing blue when cold and turns off when ready for normal driving. In some ways its better than having a needle you have to watch to see whether the car is up to temperature or not. If you are out of coolant or the thermostat has jammed, then you may see the red light.

Naaaaa...........have to totally disagree to be honest, a coolant gauge is far more useful than just a light, you have no way of monitoring a light, and often it if it comes on red it's to late, with a gauge you can watch an increasing temperature and take action "before" it overheats.

 

I thinks its very poor of ANY manufacturer who does not fit a gauge.

But the gauge is nonsense anyway. It goes up to 90 and stops there. Complete placebo and not accurate by any means. 

yes because 90° is approx normal operating temp with the thermostat fully open, well dual thermostat on the RS, if it stays there, then the cooling system is running at the correct temp. Never had it go higher as yet, so cannot be sure if it's linear above that or not, my guess it is.

 

Still more trustworthy to me than a light.

That’s just perception though. 

 

The red light comes on at 120 degrees so below ‘boiling’ but above normal operating parameters. 

The red light is on before 120*oC, 

 AntiFreeze / Summer Coolant Boiling point is 106*oC normally and some stronger ratio's, & Waterless can be 113*oC.

Its a shame for those who could take something from a genuine temperature reading such as knowing if the thermostat is getting a bit tired and running slightly cooler.

 

But on the other hand, can you imagine how busy the forum would be if the gauge actually read a direct coolant temp. people would lose their mind now they are used to seeing it at 90 all the time.

I thought with the later 1.5 bar caps it was now higher, glad to be corrected.

I don't think there is a "thermostat is getting a bit tired" more it works or it breaks, it is a mechanical part. If it breaks open, you have the blue light too long and if it breaks closed, you will get the red light.

 

Gauges are pretty much worthless, like the economy gauge that used to be fitted to the Octavia that would show how efficient your driving was in the E gear that everyone now called fifth.

I disagree, you buy any VAG car between 5-10 years old as I have done many times and the gauge reads 90 perfectly. You log some temperatures and you soon figure out your running 5-10 degrees cooler than you should be which you would notice if the gauge didnt read 90 anywhere from 70-110 which is my entire point.

 

Thermostats rarely fail fully open or fully shut, they just fail to shut fully more and more until it gets so bad you notice. In a diesel in wintertime when they take forever to warm up as it is, every little helps.

...Everyones gone off on such a tangerine that the original OP is now having his/her head spin round!

The reading they are getting is as it should be, all working properly. Job done. Move on!
