I just purchased a used Audi A3 and noticed that the engine is making a loud knocking noise. It seems to occur when the car is idling or accelerating. I'm concerned that this could be a serious issue. Can anyone offer some advice on what could be causing this and how to fix it?
ReplyJohn, it sounds like your engine may be experiencing a misfire. This could be caused by faulty spark plugs, a clogged fuel filter, or a variety of other issues. I recommend taking your Audi to a trusted mechanic to have it diagnosed and repaired.
I had a similar issue with my Audi A3 and it turned out to be a problem with the fuel injectors. It's always best to get a professional opinion, but it wouldn't hurt to check the injectors as well.
If the knocking noise only occurs when you accelerate, it could be a sign of low oil pressure. Make sure to check your oil levels and get an oil change if needed.
