How often should I change the engine coolant in my Audi 80?

I recently purchased a used Audi 80 and I'm not sure when the previous owner last changed the engine coolant. I want to make sure I'm maintaining the car properly, so how often should I change the coolant? Is there a recommended mileage or time interval?

It is generally recommended to change your engine coolant every 30,000 miles or every 3 years, whichever comes first. However, it's always a good idea to check your owner's manual for the specific recommendations for your vehicle.
