I've noticed that my Audi A3's engine makes a knocking sound when I accelerate, especially at higher speeds. What could be causing this and is it something I need to worry about?
ReplyThe knocking sound could be caused by low quality or dirty fuel, which can lead to engine knocking. It's important to make sure you're using high quality fuel and regularly get your fuel system cleaned.
Another potential cause of engine knocking in an Audi A3 could be carbon buildup in the cylinders. Consider using a fuel additive that can help clean out the carbon and improve engine performance.
