What is the best way to maintain the engine in an Audi A4?

I recently bought a used Audi A4 and want to make sure I am properly maintaining the engine to prolong its life and avoid any major issues. I am a bit confused about what the recommended maintenance for an Audi A4 engine entails. Can anyone provide some guidance and tips?

The best way to maintain the engine in an Audi A4 is to regularly change the oil and all filters according to the manufacturer's recommendations. This will ensure that the engine remains well lubricated and clean. It is also important to follow the recommended service intervals for other important engine components, such as the timing belt and spark plugs.
