How should I properly maintain my Audi A7's engine?

I recently purchased a used Audi A7 and want to make sure my engine is in top condition. What are some essential maintenance steps I should take?

Regularly check and change your oil according to the manufacturer's recommendations. This is essential for keeping your engine running smoothly.

Keep an eye on your coolant levels and make sure there are no leaks. Low coolant levels can lead to overheating and potentially serious engine damage.

Don't forget about your air filter. A dirty air filter can restrict airflow and reduce engine performance. Replace it every 12,000-15,000 miles.
