I've noticed a strange humming noise coming from my Audi A7's engine when I accelerate. It seems to be happening more frequently now. What could be causing this and how can I fix it?
ReplyIt is possible that your air filter needs to be changed. Check the filter and if it looks dirty or clogged, replace it. This should help improve the engine's performance and eliminate the strange noise.
Another common cause of strange engine noises is a faulty spark plug. Have a mechanic check and replace any worn or damaged spark plugs to see if that resolves the issue.
