Mine doesn't cut out completely, I have the exact same behavior as the OP.

I will see what price I can get on the LPFP

Thanks for ebay link mate, I am handy with most stuff will no doubt give this a go. Replacing the high pressure pump is a job I wasn't prepared to tackle but replacing the LPFP seems not to bad.

Don't fit that pump. They are Censored

Saves you taking the tank out twice Thumbs Up

Do not waste your time on kits. The link I sent from UK supplier comes with 2 year warrantee and after messing around get it out, the last thing you want to do is start stripping it to fit the kit.

Problem Solved

Finally got some time to look at this issue after some invaluable advice from various members as always Bow down Glad to report that it seems to be resolved Thumbs Up

I tried to do a "how to" but 3 failed attempts to upload the photos is enough. I've added in some below and the rest are in my Gallery if anyone is interested.

Dropped the tank as per instructions elsewhere on the forum;




Removed access cap from top of tank







Pump is in fact located to the rhs as seen in the pic below, secured by the convoluted green strap. Pulling on the green hoop releases the pump unit however take care when removing the pump as the float and arm of the fuel gauge sender unit is also attached and needs carefully manoeuvred out.




Unit finally removed




Prior to changing the unit out, I checked that the wiring to the pump was all ok. Taking advice from the forum, I confirmed that there was full battery voltage (11.6v as car had not been started for 24 hrs), showing between the positive feed on the female end of the multiplug and ground and that between the negative terminal and ground, there was less than 0.01volts, confirming that the wiring appeared to be fine.








Now back to the tank. Below you can see where and how the pump unit is/was located.



After swapping over the fuel gauge sender unit onto the new unit and a bit of gentle wrestling, the new unit was fitted and everything all cleaned and replaced;




Refitted everything in reverse to it being removed and also fitted a new fuel filter at the same time. Cycled the ignition a few times and heard the pump kicking in and pressurising the system. Purged air out of Schrader valve in engine bay until I got good fuel flow. Took a couple of sputtered attempts to fire up but ran fine after that.

Three weeks in and I can gun the throttle now without any issue or dreaded ESF message so I feel confident that the issue is fixed. Took me a full shift but was taking my time and learning as I was going through it. Must admit, I was a bit surprised when I realised that the pump was not directly below the access cap in the tank and somewhat apprehensive at wrestling all the gubbins in and out, but slow and methodical and it is fairly straight forward.

Many thanks again for all the advice guys Thumbs Up There are more pics in my gallery for anyone interested/wishing to tackle and I'm happy to answer any questions also (if I can).

Great writeup mate.

Just to update my issue, due to other issues I didn't have the funds & started cycling to work instead (the wife taking my car as opposed to the D3). Even in Perth we get rainy days so I had to limp it to work on occasion and as I did I noticed it took more effort to get ESF to kick in. After around 250KM it stopped happening, looking back through my texts and calendar I did notice:

15th Feb, Collected the Golf from repair garage (hence tight funds), wife insisted on adding diesel tank/injector cleaner to the D3
17th Feb, text from wife that D3 had ESF

We did suspect the additive but I only recently checked the dates. The D3 is now running just fine, even on very steep hills flooring the D3 doesn't give ESF.

I did blank the EGR valves while it was giving ESF, the soot / crap on the inlet was disgusting. This may have helped.

It is possible you had some crud causing a restriction in the fuel system i.e. partially blocked diesel filter and throwing up the ESF due to starvation, which cleared or moved as a result of adding the cleaner? Don't think faulty EGR's would cause an ESF message on their own (depending on MY ?) and the symptoms are different anyway, or in my case they were. I'd been having progressively worsening episodes of a stuck open EGR (s) which resulted in almost no low down power until over 2000RPM, but no ESF? Only when the LPFP / Diesel filter issues arose, did I experience ESF, which seems to be correct for my MY 06. I did I think about blanking the EGR's off but as with all troubleshooting, I try to change only one thing at a time, which is why I did the LPFP first and confirmed the ESF issues were resolved before tackling the EGR blanking. I did still have the low down EGR issue after sorting the LPFP issue which to me, confirms that the issues are most likely unrelated. I drove for a week after sorting the pump ( No ESF issues ) and then blanked the EGR's the following weekend as they were really playing up. This instantly resloved the low RPM/ power loss issues and has also given me and average increase of some 55 miles per tank of diesel!

Glad to hear you are sorted now and hopefully it will not come back but it is a Land Rover after all so be aware!!

I also think some dirt/crud got dislodged after using the fuel cleaner, must have worked it's way through now.

I had no EGR failure symptoms, when I had the ESF diagnosed by the specialist the computer said there was an EGR fault. As I own a 2005 model I opted to blank them off.

All I need now is a Gearbox flush and soon a timing belt. The wife also wants the software update to get the lane change indicators (3 flash).

Perhaps I am still in trouble.

The D3 took a little extra cranking to start than normal, did this twice. Then at sub 50km/h I get the ESF, pulled over for an engine re-start (again a little extra cranking) and message gone. Just a couple of hundred meters along the engine stops. Will not re-start - RAC guy believes the HPFP has packed in and I am duly trailored home.

I did notice the LPFP was making a different noise, seemed more strained and whiny. With this in mind I did several primes and bled air the valve above the HPFP. At first I got air with a little fuel, then after a few seconds I got consistent fuel. A couple of cranks and she fires up, road test all OK.

Thoughts please!

Have you done any testing of the LP fuel system?

Robbie,

I did check the current draw at the fuse box, 4.2A

I don't have a pressure / vacuum unit but I will buy one tonight, although may ship it from the UK so will be 2 weeks.

Would air in the diesel line cause the engine to cut out?

Bob.

Did you bleed the LP system through the nipple valve?
