I've noticed a knocking sound coming from the engine of my Audi A4. What could be causing this and how can I fix it?
ReplyOne of the common causes of engine knocking in the Audi A4 is low quality or incorrect oil. Make sure to use the recommended oil and change it regularly to avoid this issue.
Another reason for engine knocking could be faulty spark plugs. Get them checked and replaced if necessary to improve engine performance.
Clogged fuel injectors can also lead to engine knocking. Consider getting them cleaned to improve fuel efficiency and reduce the knocking sound.
