Why is my Audi A4 making a rattling noise during acceleration?

I have noticed a rattling noise coming from my Audi A4 whenever I accelerate. It seems to be coming from the engine area. What could be causing this issue and what should I do to fix it?

It could be a loose heat shield or exhaust component. I suggest bringing your vehicle to a trusted mechanic for an inspection and repair if necessary.

You may also want to check your engine mounts as they can wear out over time and cause unusual noises. Get them replaced if needed.

One possible cause could be the timing chain tensioner. This issue should be addressed by a specialist at an Audi dealership.
