Hi All

During the recent v cold weather my car has been flagging the red coolant warning light on first start in the morning. This implies low coolant level or excessive coolant temp, but neither are applicable as is cold start and level has been checked and is fine.

When the engine has run for just a few minutes and is restarted the light does not re-appear.

Has anyone else had this issue in the recent v cold weather? Is it just a problem with frozen moisture in the expansion tank sensor or something?

Cheers

Andy

Having the same problem here but learning to ignore it. Temps all seem fine, car warms up as normal, just one of the quirks of owning a skoda lol

A new expansion tank should fix this - the sensor is part of it. The part is cheap enough (around £15) and apparantly straight forward to change.

I had the same with mine this morning. It was reading -12 on the outside temperature gauge, but this afternoon it was fine at -6

Same here yesterday morning - stayed on after ignition - switched it off after 5 mins whilst I de iced the car - never came back on again when I re started her. Minus 6 at the time but minus 9 over night. First time its happened to me and didnt happen again this morning so I am ignoring it (just ordered new discs, pads, cam belt change, service, new bushes and new tyres for this Thursday - ouch that is going to to hurt the wallet!

I have this problem on my Oct as well. As JulieD points out it will probably need a new tank. I've tried cleaning the sensor but to no avail. I know the levels are ok so i'm happy to ignore it for now.

This seems to be a fault triggered by the cold weather, doesn't it. It's come up SO many times in the last few weeks...

Yeah i noticed that last year, which was when mine also played up. However, i just ignored it, and its not come in a good few months now. Strange

New tank. Just the sensor mis-reading, you can sometimes over-fill the tank to stop it complaining..

Im having this problem aswell on really cold days. On warmer days it doesnt show.

I just ignore it as everything seems fine.

Just ordered one of these for my car too as I've got sick of driving a mile down the road and turning the engine off and back on again to stop the flashing red light

I've had this the past few days aswell, I put some neat antifreeze in it last night and this morning it was fine and that was at -17c.
