I have noticed a strange noise coming from my Audi A4 engine. It sounds like a rattling or humming noise. It only seems to happen when the engine is running and gets louder when I accelerate. What could be causing this and how can I fix it?
ReplyIt is always best to get your Audi A4 inspected by a mechanic if you are experiencing strange noises. However, if you want to try troubleshooting it yourself, the first thing to check would be the serpentine belt. It could be loose or worn out. Also, check your air filter and engine oil levels. If everything seems fine, it may be an issue with the timing belt or a faulty water pump. In any case, it's best to get it checked by a professional to avoid further damage to your engine. Best of luck!
