I have been experiencing a rattling noise coming from my Audi A4's engine. It started a few days ago and seems to be getting louder. Is this a common issue and what could be causing it?
ReplyThe most common cause of a rattling noise in the engine of an Audi A4 is a loose heat shield. This can be easily fixed by tightening the bolts or replacing the shield if it is damaged or rusted.
Another possible cause of a rattling noise could be a faulty belt tensioner. This can cause the belt to slip and make a noise. It is recommended to have it inspected and replaced if necessary.
