My Audi A3's engine is making a rattling noise and I'm worried it could be a serious issue. What could be causing this noise and how can I fix it?
ReplyIt could be caused by a loose or worn out pulley, which can be easily fixed by tightening or replacing it.
The noise could also be coming from a worn out timing chain or tensioner, which will need to be replaced by a professional mechanic.
Make sure to check your oil level and quality, as low or dirty oil can also cause engine noise. Consider getting an oil change if needed.
