How is AA radiator flush done in my Audi TT 2001?

To perform a radiator flush on your 2001 Audi TT, first ensure the engine is cool and then drain the coolant by opening the drain plug at the bottom of the radiator. Next, fill the system with a radiator flush solution mixed with water, run the engine for about 10-15 minutes with the heater on, and then turn it off. Afterward, drain the flush solution and thoroughly rinse the system with water until it runs clear. Finally, refill with the appropriate coolant mixture for your Audi TT and check for leaks.
