Heres a weird scenario. Its 0^o outside, i turn the car on and get the red overheat warning light flashing at me, the car has been stood still all night so it has no heat in it what so ever. The light does not go out again until the engine is restarted

THis is the second time in 2 weeks.

Anyone any ideas

Sounds like a faulty temperature sensor.

The light will have logged a fault code on the cars ECU.

Any garage with diagnostics equipment will be able to read the code and confirm the fault pretty quickly.

Or better still find a member on here with VCDS who may do it for free instead!

This is assuming the car is no longer under warranty?

If it still has protection then time to get it booked in to a local Skoda dealer.

It's November; odds on it's the usual deposits on the level sensor problem.

To fix it, on a cold engine, open coolant filler, take a largeish flat blade screwdriver, say 5mm, and gently scrape it up and down the 2 metal prongs you can see.

It is well out of warranty ('07 plate with 86k on the clcok). Does anyone know how much a sensor is and how much it is to fit it.

I'd be trying the solution is post #4 first...

Ill give that a go at lunch and see if that sorts things. If these metal prongs are covered in crud and i scrap them then i assume the scrappings are ok in the coolant system

got exactly the same thing did cleaning the prods fix it?

You sure its not your coolant/antifreeze low??? mine was low the other morning coming home from work but it was low so a tip toe'd home keeping an eye on the gauge as it was going for a timing belt water pump change that morning.

OK, got a tooth brush and poked it in through the top of the expansion bottle and gave the two prongs a good scrub, no problems since But I have no idea why this only occured when it was very cold :think:
