Thanks for your help. I am trying to source the correct part from the links you provided but they have asked me to confirm the part number but I don't have the unit out yet. Is there no way of finding this out before taking the old pump out?
I also asked advice from a guy I know that works for a LR service garage in Toulouse. He said it was a very big job requiring specialist tools and lots of experience. Is this correct? I don't think for one minute it will be easy but is it possible with a basic set of tools and a few days? Cheers

It's certainly awkward and there's nothing enjoyable about it, but as to your abilities/skills nobody can answer that but yourself.
However, before you jump in to this you need to consider if the HPFP is actually at fault here!! Do you have a diagnostic tool that is leading you to this conclusion, or are you simply going on what the garage has told you? It is not possible to maintain one of these vehicles yourself without a good diagnostic tool (GAP IID et al)
So if your garage is proposing a bill of €2,200 you need to think very hard on this point if you do not have your own diagnostic tool!
As for pump replacement if you haven't done this kind of work previously it will challenge you, and whilst there are no "special" tools needed (other than mentioned above) a very comprehensive set of tools including torque wrenches is required along with patience and a methodical approach. Perhaps the most challenging aspect might be the rear cam belt as access is very restricted as are the rear bolts for the pump. My advice would be to read thoroughly the relevant posts on the forum first, where others have shared their experiences before you decide to jump in yourself.
If you do dive in there will be help along the way from members on here. Pay strict attention to the torque values for all fasteners and other procedures and you should be fine. (pics before you start and during the work will be invaluable!!) The manual is available here on the site for all the tech data but it's not great for diagrams etc but useful nonetheless.
As for the correct HPFP there are two types fitted to the D3 depending on year of manufacture. One for early production models (EU3 emissions) up to chassis number 6A999999, and one for later (EU4 emissions) which applies to vehicles from chassis number 7A000001 and above and with DPF.
So if you have a decent diagnostic tool have a go and save yourself from being ripped off by the garage with their €1850.00 replacement pump + labour. If you don't have a diagnostic tool doing this job yourself will pay for it three or four times over. Good luck yµ (idµ - eAµ) ψ=mψ
