I have noticed that my Audi A2's engine emits a rattling noise when it is idling. The noise goes away when I accelerate, but comes back when the engine is back at idle. What could be causing this issue?
ReplyThis could be due to a loose or worn out fan belt. It is important to get this checked and replaced if necessary to prevent any potential engine damage.
The rattling noise could also be coming from a faulty pulley or tensioner in the engine. It is best to have a professional mechanic diagnose and fix the issue.
It is possible that there is an issue with the exhaust system, such as a loose or damaged heat shield. Have a mechanic inspect the exhaust system to determine the cause of the rattling noise.
