How do I perform a coolant flush on my Audi R8?

I recently purchased an Audi R8 and I want to make sure I maintain its performance. Can you provide step-by-step instructions for performing a coolant flush on this particular model?

To perform a coolant flush on your Audi R8, first make sure the engine is cool and the car is parked on a level surface. Locate the radiator drain plug and place a drain pan underneath. Loosen the drain plug to drain the old coolant. Once drained, tighten the drain plug and refill the radiator with a 50/50 mixture of coolant and distilled water. Start the engine and let it run for a minute. Then, turn off the engine and allow it to cool down. Repeat this process until the coolant level stays consistent. Remember to also check and top off the coolant level in the reservoir.
