Its a 2003 A6 Quattro sport.
No one seems to know what this noise is (maybe bad water pump?)

Thanks!

Might be a bad water pump or a bad serp belt idler. Remove the serp belt and spin the rotating parts by hand to isolate the source.

Power steering pump? Any change when you turn the wheels when stopped? Sounds like mine did. Mine was low on fluid and I do have a slow leak, but not worth fixing yet.

Sounds like power steering pump. Remove the green cap on the driver's side of the engine bay. That is the reservoir for the fluid. Requires a mineral oil based fluid. Pentosin fluid is available at O'Reilly's Auto parts for a reasonable price. Maybe available elsewhere as well. If not the fluid level follow georgeb's advice. Also near the end of the second video it looked like the belt was flapping like it was de-laminating. Or were my eyes deceiving me?
