I need help with an 2001 Audi A6 Station wagon warning light.?

It started when the weather got cold but the temperature warning light keeps coming on but the car doesn't show that it is overheating. The O2 sensors need to be replaced according to the part store cuz the check engine light is on. Is the warning light linked to that or what could it be?

    you need an electronic diagnosis, the parts store cannot diagnose a problem unless they connect your car to a computer, take it to an audi specialist or a dealer, do NOT top up with distilled water top up ONLY with Audi certified red or green coolant as specified for your car, look in the transparent reservoir and see what the level is, you should also be able to see the color

    Check the level of the antifreeze at the expansion tank. If it is low, top it off with distilled water.

    Have you checked that the radiator is full? You need to take it to an audi service agent & get them to diagnose it.
