How to troubleshoot a malfunctioning engine in my Audi?

I recently noticed that my Audi's engine is not performing as well as it used to. What steps can I take to diagnose and fix the problem?

First, check the oil and coolant levels. Low levels can lead to engine issues. Also, pay attention to any warning lights on your dashboard.

If your engine is making strange noises, it could be a sign of a larger issue. It's best to take it to a mechanic as soon as possible.

Regular maintenance is key for preventing engine problems. Make sure to follow your Audi's recommended service schedule.
