What should I do if my Audi A6's engine is overheating?

I have noticed that my Audi A6's engine temperature gauge is higher than usual. What steps should I take to prevent any further damage?

First, check to see if there is enough coolant in the radiator. If there isn't, fill it up and see if the temperature gauge goes back down. If not, there may be an issue with the coolant system that requires a mechanic's attention.

Make sure to also check the radiator hoses for any cracks or leaks. If there is damage, replace the hose to prevent any further overheating.

Another potential cause of overheating could be a faulty thermostat. If the thermostat is stuck closed, the engine may not be able to cool down properly. Have it checked and replaced if necessary.
