How do I ensure my Audi A7's engine runs smoothly?

I've noticed my Audi A7's engine has been making strange noises and running a bit rough lately. What steps can I take to make sure my engine is running smoothly and efficiently?

It's important to regularly check and top up your engine oil to prevent any potential engine issues. You can also consider using a higher quality oil or adding an engine oil additive for better performance.

Make sure to schedule regular engine maintenance and tune-ups to keep your engine in top shape. This includes changing spark plugs, air filters, and other necessary components.

Pay attention to your engine's temperature gauge and coolant levels. Overheating can cause serious damage to your engine, so make sure to address any cooling system issues promptly.
