How to Fix a Faulty Engine in an Audi A3?

I recently purchased an Audi A3 and noticed that the engine is not functioning properly. It seems to be making strange noises and the performance is not up to par. What steps can I take to fix it?

First and foremost, it is important to properly diagnose the issue with your engine. This can be done by taking it to a mechanic or using an OBD scanner to retrieve error codes. Depending on the problem, you may need to replace certain parts or repair any damage.

Regular maintenance is key to keeping your engine running smoothly. Make sure to change your oil and filter regularly and check for any leaks or damage. Also, be sure to use high quality fuel and always keep your gas tank at least half full to prevent any issues.
