Why does my Audi engine make a knocking noise?

I recently noticed a knocking noise coming from my Audi's engine, especially when accelerating. It's a 2018 model with low mileage. What could be causing this and how can I fix it?

The most common cause of knocking noises in an Audi engine is a faulty fuel injector. This can be resolved by getting the injector replaced or properly cleaned by a certified mechanic.

Another possible cause could be low engine oil level. Check your oil level and top up if needed. If the noise persists, it's best to take your car to a professional for a more thorough inspection.

In some cases, a faulty engine mount can also cause knocking noises. This can be fixed by getting the mount replaced by a qualified mechanic.
