A prspective on the HPFP problem:
From BMW SIB 13 03 09, Fuel Systems January 2010: "We estimate that only a small percentage of vehicles will actually develop a problem."
Christoph Rauwald, DOW JONES NEWSWIRES, quotes BMW AG (BMW.XE): "Vehicle sales in 2009 fell 10.4% on the year to 1.29 million cars, but BMW retained the crown as the world's best-selling premium car maker ahead of Daimler AG's (DAI) Mercedes-Benz brand and Volkswagen AG's (VOW.XE) Audi AG (NSU.XE) unit."
The SIB dealing with the HPFP is much less specific than the BMW financial report, likely because the reliability of the pump is of not enough concern
to the company.
