The only blue light on mine is the full beam.

if you look in the manual it'll say what it is.

if the symbol is similar to any of our lupo's, we'll be able to say.

Hi elizabete, do people flash you coming the other way?

On some VAG models the blue water temperature light comes on until the engine is up to normal operating temperature. not sure if your car will have this but it depends on the specification for your country as some countries by law need this function for the emissions systems.

The 3L do not have a temperature gauge for the cooling water. If the engine is under 20 degrees celsius the blue temp mark will light up.

I think your temperature sensor may be broken.
