HPFP failed
« on: June 03, 2011, 01:01:39 pm »
As per the title. Been misfiring under load (despite new coils/sparks) and actually lost throttle response sometime last week on the way in to work. Had a suspicion it was the fuelling system for a while. VW have been investigating and told me yesterday the HPFP has failed... so got an APR one on order from JKM. Should be with me (and hence VW) tomorrow. Bah.

Was it an uprated pump that failed or an oem one?

OEM pump, original pump from the factory.

Figured may as well get the APR pump to replace it.

...apparently cam follower still looks OK after 107k miles!

OEM one is about £160, don't see the point in APR unless you are chasing power.

can achieve 250 without the need for an aftermarket high pressure fuel pump, just get the standard one as said above at around 160ish

Yeah including VAT and next day (Saturday in this case) it was £764. Hefy wodge of cash. APR was chosen just for its improved overhead over OEM one, I'm not after silly numbers as well (something else would just break) and admittedly my OEM pump only did fail after 100k miles.

Before my pump started having issues my car was putting out just shy of 250 (it was 249  :laugh:) with pump on the way out around 20 horses went missing and it's been on its way down.

make sure they categorically gauarantee that the cam and follower are ok, sounds v suspicious to me that the pump failed yet the follower is ok??? What was the failure mode? sounds like worn or broken plunger in which case I would have expected worn follower, and potentially cam, unlikely plunger would wear that much (to cause fuel cut and power loss, whilst follower was in good condition...........
