How many fuel pumps?? TD4 05 plate

Wafuboy · Feb 12, 2015

Hi guys, I've had an ongoing issue with fuel, had the rac out today and they've Told me the code reader is saying low fuel pressure. I fitted a new fuel pump and filter a month ago, I changed the one in the o/s rear wheel arch. Is there another that could be causing the problem? One in the tank?
It could well be that I've got a dodgey new one as it is very loud.
Any help appreciated thx guys

Sorry it's

Only one low pressure pump on a 05 Td4

If it's loud then likely to be struggling for pressure

Where did you buy it from and for how
Much?

Sounds like your new pump is an ebay special. Genuine and OE pump costs app £120 anything less and your usually buying noisy premature failing crap.

is the fuel filter integral? If not change that as well.

Fuel filter is in the mounting bracket in a plastic tube and is a right bugger to get out as is seizes into the tube. Should be changed every 60,000 miles but is often missed during servicing, mine had done 110,000 miles and was the original. Grease well when replacing.

Yeah, that's what the garage told me..the darned car would barely go over 50mph and the warning light kept coming on.

Turned out it probably hadn't been serviced for 40k miles. All filters and fuel pump changed and its a new beast.

Its odd because the older TD4 with two pumps would run perfectly with a failing rear pump. Until it wouldn't run at all

Thx guys I'll return the part for a new as its under warranty, it is a OEM part but a cheaper one as I've already gone through 2 already

The problems I'm encountering could also be the electrical connections on the fuel pressure sensor I think having read up on it, I'll do the pump agin first as the curent one is very loud.
THANKS FOR ALL THE HELP :clap2:

just a point of technical interest. When mine was going garage said it might be electrical etc. I said no, because in my experience electrical stuff is 99% go/no go. That is either its working good, or not working at all or solidly at some lower level of performance. Mechanical issues however can be all shades of grey in between. In my case the car was sometimes nearly OK/ to wouldn't start at all/ with all shades in between. Ergo I did not suspect sensors with dodgy connectors.

The garage also said they had measured the fuel pressure that was IIRC 200psi when 350psi is what it should have been..fairly conclusive.
