Thread: TDV6 High Pressure Fuel Pump

I've been having intermittent fuel-related problems for the last 4000-odd kms. There are no symptoms as such - just a "Dong" and the car goes into limp-home mode. Turn off, wait a minute, re-start and away we go again...for maybe 200 metres or 2000 kms. Initially I suspect it was a tank of contaminated diesel I picked up down in Victoria after their recent fuel shortage. I took it to the nearest dealer who replaced the fuel filter (which was about 30% blocked) and everything seemed fine....for a while! After 2500 kms it happened again! This time I decided to take the risk of driving all the way back from Vic (with the van in tow) to Brisbane so I could take it to my usual mechanic (not a dealer). The car performed faultlessly the whole way! I've just had my mech go over it and he found two things -

1. Faulty oil temperature sensor in the sump indicating the oil temp was -3degC;
2. Fuel rail pressure fault - low fuel pressure at 3000rpm.

The faulty oil temp sensor may or may not have had anything to do with it, but he says the low fuel pressure means a faulty high pressure fuel pump - and it's apparently very expensive (and difficult) to replace. Does anyone know approx how expensive?

Another point is that there was a related recall a couple of years ago (recall #P008) in which the h.p. fuel pump was apparently replaced with a newer design - the old ones had front bearings which were failing. I had this recall done just under 3 years ago. Does anyone know if such recall work is warranted, and if so, for how long?

Cheers

Just had a Miriad of errors come up. Engine system fault, suspension lowered, transmission fault, limited gears available, park brake fault, HD fault system not available. Car then goes into limp mode with a couple of Amber leaves lights. Took their car to specialist in Geelong, and told it is caused by a HP Fuel pump issue... as there was low fuel pressure on the diagnostic and want $3500 to repair. Any thoughts?
