I recently noticed that my Audi A4 produces a high-pitched whining noise when I accelerate. It seems to be coming from the engine, but I'm not sure what could be causing it. Can someone please explain why this is happening?
ReplyThe most common cause of a whining noise in an Audi A4 is a worn out serpentine belt. This belt is responsible for powering multiple components in the engine, and when it becomes worn, it can start to make noise.
