How do I know if my Audi A5 needs a coolant flush?

I recently bought a used Audi A5 and I'm unsure if the previous owner has done a coolant flush. How can I tell if my car needs this service? Any recommendations on how often I should get a coolant flush? Thank you.

One way to check if your Audi A5 needs a coolant flush is to look at the color of the coolant. If it is a dark color or contains visible debris, it's time for a flush. Another indication is if your car is overheating or the temperature gauge is higher than normal.

I would recommend getting a coolant flush every 50,000 miles or every 2-3 years, whichever comes first. This will help keep your engine running smoothly and prevent any potential damage.

If you're still unsure about whether or not your car needs a coolant flush, it's always best to consult with a certified mechanic. They can perform a more thorough inspection and advise you on the best course of action.
