Default Fault in cooling system - warning light

Hi all,

I live in the UK, and the past 2 mornings when starting up my 03' 1.8TT,a warning light comes on which I have since discovered is supposedly for a fault in the cooling system. It's the same symbol as the oil temp, but it comes up full size and in red.

It stays on for about 2-3 minutes, and then goes off. Both morning's it has been very cold (well - not compared to the ice-storms but it's been between 0c and -2.5c so colder than it has been. Bothmornings I have sat not movingfor a couple of minutes with the engine running but got bored of waiting for it to go off, so have started carefully on my journey, and within 30 secs to a minute, it goes off and I don't see it again.

Any ideas? Is this something I should worry about?

Thanks,

Karen

top off your coolant. I'm guessing that as your TT warms up the coolant expands and its no longer showing low.

Yes, just make sure you use G12 Pentosin. You CANNOT mix coolants!
