Does a vr6 even have a HPFP?

So the08 v6 gasser doesn't have hpfp ?

No, the HPFP is on a diesel only. I had one fail on my Jetta TDI cup. Glow plug lit and the car died about 10 miles later, after I made it across the bridge You do have a fuel pump, I think 2 of them but not HPFP. At least when your pump dies it won't shoot metal through your fuel system.

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

GL!

Ok, I just never heard of one blowing up like the diesels.
