What does the coolant light in an Audi 80 mean?

I recently noticed that the coolant light in my Audi 80 was on. What does this mean and what should I do?

The coolant light is indicating that the engine is running too hot and the coolant level may be low. It is important to check the coolant level and top it off if necessary.

The coolant light could also indicate a problem with the coolant temperature sensor. It's best to have a professional check this out to avoid any potential engine damage.

You may also want to check for any visible signs of a coolant leak, such as puddles under your car. If you see a leak, it's important to have it repaired as soon as possible to avoid overheating.
