Why does my Audi's engine have a strange noise?

I recently noticed that my Audi's engine is making a strange noise that it didn't make before. How can I fix this issue?

It is important to have your Audi regularly serviced by a certified mechanic to prevent any potential issues. Additionally, make sure to use high quality fuel and oil for your car's engine.

It could be a problem with the engine oil levels or the quality of the oil. I suggest taking your car to a trusted mechanic to have it checked and possibly get an oil change.

Check for any loose or damaged components in the engine area, such as belts and pulleys. These can often cause strange noises and should be fixed immediately.
