Why is my Audi A3 experiencing strange engine noises?

I recently noticed strange noises coming from the engine of my Audi A3. What could be causing this issue and how can I fix it?

It is possible that your engine's timing chain tensioner may be malfunctioning. This can cause strange noises and should be addressed by a mechanic as soon as possible.

Another potential cause could be a faulty valve in your exhaust system. I would recommend taking your car to a certified Audi technician for a proper diagnosis and repair.

Ensure that you are using the correct engine oil for your Audi A3. Using the wrong oil viscosity can also contribute to unusual engine noises.
