Why does my Volkswagen Passat make a strange noise when I accelerate?

I recently purchased a used Volkswagen Passat and I've noticed that it makes a weird noise when I accelerate. It almost sounds like a grinding noise. What could be causing this and is it something I should be concerned about?

It's possible that the noise is coming from a worn out belt or pulley. I would recommend taking it to a mechanic to get it checked out.

The noise could also be caused by a problem with the transmission. I would recommend taking it to a Volkswagen dealership for a proper diagnosis.

I had a similar issue with my Passat and it turned out to be a faulty exhaust manifold. I would suggest bringing it to a certified Volkswagen mechanic for a thorough inspection.
