Common Issues with Audi's Engine

I have been experiencing some trouble with my Audi's engine lately. It has been making a strange noise and sometimes takes longer to start than usual. What could be causing this and how should I handle it?

It is important to regularly check your Audi's engine oil level and quality. Low oil level or poor quality can cause engine damage and lead to these issues. I suggest getting your oil changed and keeping an eye on the level and quality.

Another possible cause could be a faulty spark plug. If the spark plugs are worn out or dirty, they can cause the engine to struggle to start and produce unusual noises. Consider replacing the spark plugs and see if the issues persist.
