The following question about an "UPDATED" BMW water pump was asked today:

I see two different ones here at Turner Motorsport...

Here is the text for the first URL above (engine_m50_h20_pump.jpg):

Water Pump - M52tu, M54 (Original BMW)
Part #: 11517527910 (11-51-7-527-910)
This Original BMW water pump is the latest updated design with a composite impeller. The composite material (similar to Kevlar) is much stronger than the problematic plastic impeller from past water pumps. And it's lighter than the aftermarket metal impellers so that means less strain on the bearing. For an OE/OEM replacement, we have found that this is the highest quality and longest lasting waterpump available.

This waterpump fits the following BMWs:
1999-2006 E46 3 series - 323i, 323Ci, 328i, 328Ci, 325i, 325Ci, 330i, 330Ci
1999-2003 E39 5 series - 528i (4/99+), 525i, 530i
1999-2002 Z3 Roadster/Coupe - Z3 2.8 (4/99+), Z3 2.5, Z3 3.0
2004+ X3 SAV - X3 2.5 & 3.0
2000-2006 X5 SAV - X5 3.0
2003-2005 Z4 Roadster/Coupe - Z4 2.5 & Z4 3.0
Price: $104.95 (USD)

Water Pump - M50, M52, M52TU, and M54 Engines with Metal Impeller
Part #: 11511433828 (11-51-1-433-828)
The early M50/M52 engines had a serious weak point: the water pump. BMW originally used a plastic impeller in the waterpump. This would degrade over time and eventually break apart. Your car overheats immediately. This water pump is an updated one with a metal impeller. BMW has since released a water pump with a composte impeller that does not have the same issues and is just as reliable as the metal impeller version. But for piece of mind, the metal impeller is tough to beat.

This waterpump fits the following BMWs:
1999-2006 E46 BMW 323i, 323Ci, 328i, 328Ci, 325i, 325Ci, 325xi, 330i, 330Ci, 330xi
1997-2003 E39 BMW 528i, 525i, 530i
2004-2010 E83 BMW X3 2.5i & 3.0i
2000-2006 E53 BMW X5 3.0i
1997-2002 Z3 BMW Z3 2.8, Z3 2.5, Z3 3.0, MZ3 (S52)
2003-2005 E85 BMW Z4 2.5i & Z4 3.0i
Price: $59.95 (USD)
