Mine is an 06/03 build and I think the FPR is integrated in the filter. I'm going to buy the Bosch unit and see how it goes. On an '06 I once owned the pump died at 70k, so I'm still ahead with this one. While waiting for the new fuel pump to arrive, I will do the drive shaft boots and the injector O-rings.
This afternoon I went ahead and removed the sea of plastic covers on the engine, all the quick-ties holding the wiring and the fan/shroud. Tomorrow I'm tied up most of the morning but I should be able to find time to take the stiffener plate off and disconnect the starter wire and the oil level wire. With a bit of luck I can get the O-rings and the drive shaft boots done by Thursday evening. In all I expect the car to be laid up for the week....
On Friday I promised to do a set of drive shaft boots on a friend's GL class that I host while he is overseas. (Very similar suspension set-up to an E70 there
) No shortage of projects this week!
