Volkswagen has steered away from 2000 bar pressures in their TDI's for the Passat model in 2012, instead going for either 1600 or 1800 bar pressures max, with solenoid injectors by bosch instead of piezo injector systems, and are relying moreso on Blue tek or adblue diesel exhaust fluid scrubbing systems and a diesel particulate filter to clean up the slightly dirtier exhaust output of the lower pressured pump and injectors.
It's still early in the hot season, but to date, the only HPFP's that have failed in 2012 Passat TDI's have been gasoline misfuels mishaps by the missus new to diesel fill ups. Vw has now issued bright yellow stickers for around the fuel filling area in the past 3 days via mail to address the ignorant mis fueling owners, and to prevent themselves from being on the hook for fixing a $10,000 gas in HPFP scenario on their dime.
Considering that the Bosch CP3/4 value equation to the OEM customer is their higher priced pump meant lower cost in tailpipe treatment (because when working as claimed, it reduced particulates with higher pressure), it is a pretty big climb down to have VW, a German firm, of all companies, go to lower pressure and abandon their matching piezoelectric injectors.
Loss of face....
Loss of Teutonic arrogance...
Loss of German engineering prowess reputation...
OWCH.
How many former Bosch engineers are now on the Eastern Front?
