Check coolant light comes on when starting the engine.

[davidmiller]

I started the car up yesterday morning, after a few seconds the light came up red and flashing and message saying check coolant in manual. After it warmed up a bit i turned engine off and started it again and light went out. I used the car for a couple of hours with no problems. This morning the light was back first thing. I let it idle a bit then started it up and no light.
Any ideas? The coolant is full.

Faulty sensor

Agreed - they are usually in the expansion tank.

Frost overnight! Is the anti freeze strength correct.

B6. I just looked at videos on utube. Theres several showing the sensor in different places. It seems you take a few bits out to get to it, including battery.

Coolant is due for a change so I think it's a must.

A top up of coolant might be enough. with your car a lot of them have coolant for life. Do you know which type of coolant you have?
