Flashing Red Light

[Nimshoi1]

Hi all,

Need some advice/help please.
Started car (Ibiza Cupra 2002) this morning and having driven 100 yards the red light on the temperature guage started flashing accompanied by several beeps. Switched the engine off and on again and it hasnt come back on! Anyone got any ideas potentially what this could be?

Cheers

Rob

Low coolant poss

Possibly metal prongs in expansion bottle froze if coolant too diluted

Mine did exactly the same, it was the metal prongs as ath55 stated. However, it wasn't because of freezing. It was simply because a tiny part of the prongs was dirty, and the temperature had dropped just enough to put the coolant level on the dirty bit. As soon as the car was warmed up (even a little bit) the coolant got back on to a clean part of the track, and I never saw the warning again.

Check for low coolant, but chances are it isn't actually low because you only saw the light once. You could add a bit of coolant (or even some distilled water) just to top it up a bit and get it on to a clean part of the prongs. On the advice of someone else here I intend to get a toothbrush in there at some point and give the prongs a scrub!

Many thanks everyone, will have a look tonight and let you know.

Deposits on the metal prongs prevent a current flowing between them through the coolant.

Scrape with a screwdriver.

The same warning light comes on in my car but happens very randomly, has been through the garage to check it out but couldn't find anything wrong, any ideas?

Checked mine out filled up water & cleaned probe and now is all fine.
However it makes me now wonder where & why the water went down.
Funny enough my windows keep steaming up and it has been suggested that it might be caused by a leak in the heater matrix....ahhhhh hope not. Anyone got any views?

Check your brake fluid levels when that happens guys

This happened to me on my old mk3 cupra,but mine was a pin hole in my coolant pipe
