I think I understand where the confusion is coming from.

There is an HPFP on the FSI engine.

The fuel rail operates at 110 bar (1600 PSI). The only way to get there is an HPFP. The HPFP on the FSI 3.6 (and the smaller 4 cylinder FSI motors too) is mounted to the block and driven by the crankshaft. See page 36-38 in the attached SSP.

Now - what he describes doesn't sound like the HPFP. I would check things in this order:

  • Coil packs
  • LP Fuel Pump / Fuel Filter (tank mounted)
  • Injectors
Ok, I just never heard of one blowing up like the diesels.
