Audi S4 Power Steering Pump

[Millifera]

Hey,
Can anyone point me in the right direction to get a replacement Power Steering Pump for an Audi S4 Quattro S reg, Nov 1998? Can get one from Audio at very large price. Looking for some where a little cheaper!
Regards.

If you know the part number ebay would be a good choice.
