2009 Volkswagen Beetle rubbing or grindi. Ng noise

You know we can't see that over a computer. It's pretty certain it's not going to be a serious repair, but as a guess, I'd expect to find a sheet metal pan that got pushed up and it's hitting on a pulley on the engine. The engine rocks when shifted into drive and reverse, and that will make things change position and rub, but it should be equally at rest in park and neutral. Regardless, it won't take a mechanic long to identify the cause, and if it's a pan or splash shield, it won't take much to straighten that out so it doesn't hit anything.
