Quality of lubrication in diesel fuels does vary. If you want a little piece of mind, don't hammer on the throttle on and off, roll your foot into and out of it gently on these HPFP's, trailing throttle fuel pressures on these is absolutely brutal load and pressure wise on these pumps, and always supplement your fuel with a pint of biodiesel per 12 gallons of fuel pumped into your fuel tank, at a minimum, a qt per 12 gallons would be better.
There's really no excuse for having to baby these Bosch CP4.x HPFPs.
When we replaced our 2005 Passat TDI (still going strong in our daughter's hands), we didn't go diesel in part because of all the stories over on TDIclub.
You would think it's been sorted by now.
