You need the have the wheel bearing in that wheel checked

Losing the bearing in the blower motor maybe.

It's very likely that you need to replace the fuel pump. Usually, if its that loud either its sucking air (because you're out of gas) or the pump is about to go out.

Check front tyres & wheel bearings espesially the R/H/F. Feel tyre for high / low spots on inside & jack up & spin wheel if you get noise while jacked up it is not the tyres but wheel bearing or brake pads but more than likly a crook bearing by the sound of it. It needs to be tended to ASAP

you muffler may have a hole in it some place

You are in LIMP MODE, to protect the engine and transmission. Take to a VW dealer.

broken transmission selector, sorry you need a new or recon auto box

Are you losing power as well? if so it sounds like the camshaft is worn, this can be confirmed with a compression test
