Water temp warning light flashing from cold - 98 Polo 1.4 auto

[Scudetto]

Troops,

I used the Polo (1998, 1.4 auto, 93,000miles) yesterday and it drove fine, no problemos. I started it up from cold this morning and as I was getting my seatbelt on/tunes sorted etc, the water temp warning light started flashing. I don't think it's out of coolant (two weeks ago it was full), and I don't think there's a head gasket problem, so I was wondering whether it could be the water pump, or a thermostat playing up? (in addition to dodgy connections maybe?) Yesterday, I drove along some muck covererd roads in the rain, and I wonder if maybe some muck has spashed up and affected a sensor maybe?

Any ideas?

Anyway the light was flashing this morning, so I turned off the engine and used the Clio instead. I'll do some more checks tomorrow. Is it dangerours to the engine to drive the car to a garage with the temp light flashing?

Many thanks,

g

I've had this too on my wife's 2004 Polo 1.2.

The last couple of days were below freezing temps and the temperature warning light came on from cold. I swichted the engine off after 2 mins and on again, the light disappeared.

This happened yesterday and once before, basically when engine is started from cold in freezing temps.

Can someone has similar problem and any suggestion how to solve this ?
(ps i'm having same problem, on cold on my Mk7 polo flashes temperature light, and beeps 3 times)

I had the same with my wifes Polo. Changed the header tank, no more problems and it only cost about £14.

Not sure if its relevent - had the same on 9n polo, turned out there wasnt enough anti-freeze in the mix...

If you can get a sample test it in your freezer to check if the ratio of water to anti-freeze its ok!
