How to properly maintain and service an Audi engine?

I recently bought an Audi A4 and I'm not sure how to properly maintain and service the engine. Can someone give me some tips and advice on what I should be doing to keep my engine in top shape?

Regularly change the oil and filters according to the manufacturer's recommendations. This will help keep your engine running smoothly and prevent any major issues.

Pay attention to any strange noises or warning lights and get them checked by a certified mechanic as soon as possible. Ignoring these could lead to bigger and more expensive problems down the road.

Take your car for regular tune-ups and inspections to catch any potential issues before they become major problems. This will also help you maintain good fuel efficiency.
