Why is my Audi A4 producing a strange noise when accelerating?

I recently noticed that my Audi A4 is making a weird noise when I accelerate. It's almost like a grinding sound coming from the engine. I'm not sure what could be causing this. Can someone help me diagnose the issue?

It's possible that you may have a faulty serpentine belt or a worn out tensioner. I would suggest getting your car inspected by a professional mechanic to determine the exact cause of the noise. It's always better to address the issue before it becomes a bigger problem.

I had a similar issue with my Audi A4 and it turned out to be a problem with the exhaust manifold. I would recommend taking your car to the dealership for a thorough inspection. They will be able to properly diagnose the issue and provide a solution.
