Fixed it for you. I just don't see it as being in any way limited to BMW.

As to the plastic water pump impellor, a BMW tech has previously posted on here that as of 2010, no BMW X5 has a plastic water pump impellor, and that BMW stopped using plastic impellors in 1998, two years before the E53 was introduced, let alone the E70. I don't have a second source for that, but I don't see any diference between the plastic impellor, metal impellor, and composite impellor, they can all fail. It is an internet myth that plastic impellors are a problem these days, IMO. When the original does fail, however, if you buy an OE water pump you get a lifetime warranty on it. That should last.
