How to properly maintain my Audi A3 engine?

I recently purchased an Audi A3 and I am wondering what steps I should take to ensure the engine stays in good condition. I want to make sure I am doing everything possible to keep my car running smoothly for years to come.

Regularly change the oil and oil filter every 5,000 miles to remove any debris or contaminants that could harm the engine. Also, make sure to use high quality oil recommended by Audi.

Inspect and replace the air filter if necessary. A dirty air filter can restrict airflow to the engine, causing it to work harder and decreasing fuel efficiency.

Check the coolant levels and top off if needed. Low coolant can cause engine overheating, leading to potential damage.
