What kind of maintenance should I do on my Audi A1's engine?

I just bought an Audi A1 and I want to make sure I take good care of the engine. What kind of maintenance should I be doing and how often?

Regularly check and replace the engine's air filter every 12,000 miles to ensure proper air flow and avoid any damage to the engine. As for oil changes, refer to your owner's manual for specific intervals, but a general rule of thumb is every 5,000 miles or 6 months, whichever comes first.
