I have recently noticed a knocking sound coming from my Audi A6's engine. It seems to occur when the car is running idle and becomes louder when I accelerate. What could be the reason for this and should I be concerned?
ReplyIt could be due to old or low-quality fuel. Consider getting your car serviced and using high-quality fuel to see if the knocking sound improves. Also, check your car's oil levels and make sure they are at the recommended levels.
Another possible reason could be worn out engine parts. Get your engine checked by a mechanic and replace any worn out parts as soon as possible to avoid further damage.
