Hi Guys

 

Quick question, I have a Mk3 Superb 2.0Tsi Sportline, 4 years old, extended warranty. I have a warning light on for coolant. Not overheating, no sign of any leaks

 

Seem to re set with ignition, lights up every couple of days, twice today. Pretty sure it's a sensor, any ideas comments before I swap it out (and I assume it's the one on the header tank lid )

 

Thanks in advance

Have you checked the level?

Is it close to minimum, but say if you park on a slope the level may change slightly?

Hi John1701

 

Good shout, my driveway has a gentle slope and I've checked the level and it is below the line.

 

However, the light doesn't come on as I drive off, but during driving, some days not at all but twice yesterday

 

So, I'll top up the fluid and see what happens and report back

 

? Where did the fluid go, in a sealed system ??

 

Update. Popped into the local Skoda dealer and purchased a litre of premixed coolant for £8, put in half a litre, wait and see ?

 

Still can't see a leak though ?

If it drops again check for coolant under the inlet manifold and any signs of it below that on the sump. 2.0 tsi has a habit of leaking from the water pump. 

Good to know, I'll keep an eye on it, thanks!
