nickel4490

I would greatly appreciate any help and/or recommendations. I have a 2005.5 B7 A4 2.0T Quattro and my CEL went on for a week or so and it went off by itself yesterday. Since the CEL went on, I've heard this humming/whirring noise when accelerating and turning. I didn't get around to using the VAG until this AM, but I listed to the fault codes below. Also, I just took my car to the stealership for an oil change and they stated that I need a new "Prop Shaft Seal" w the part @ $45 and labor @ $420. Would this have anything to do with this? Is there another name for the Prop Shaft Seal? Can someone please explain what that is?

I don't know the codes or have a vag com, but you might find what you need on audizine. If you are not familiar with the site:
Just go to www.audizine.com, forums, a4 b7, then look in one of the top two stickies. I think they cover vag code or have a link to it.
Good luck
