I have noticed a knocking noise coming from my Audi A3's engine. It seems to be more noticeable when the car is idling. What could be causing this noise and should I be concerned about it?
ReplyJennifer, this could be caused by a few different factors. It could be due to a low oil level, worn engine bearings, or a loose belt. I would recommend checking your oil level and having a mechanic inspect the engine bearings and belts.
Hi Jennifer, I had a similar issue with my Audi A3. It turned out to be a faulty timing chain tensioner. I would suggest having your mechanic take a look at that as well.
