    It's a quick fix, but you need to be able to do a pump learn. I bought a valve off Fleabay (from a diese mob in WA) was about $300, but then dropped $1,000 to buy the gear to do the pump learn myself. An independent workshop could have done the learn for me for a couple of hundred bucks, but I wanted to have access to diagnostic equipment for longer trips so I bought my own instead.

    I just called land rover in Geelong and they quoted me $90 to do the pump learn. If my mechanic's tool can't do it then i will just take it there.

    I wish i had the spare cash to buy a tool to do it myself, but not at the moment.

    Just curious, which tool did you go for?

    Looks like this is the thing to check, I finished a night shift this morning and the 130 didn't want to go home, intermittent throttle response and near-stalling as I came out of the driveway.
    The file with the workshop manual extract states pressures can be up to 29,008 PSI!!!
    I have just sent my nanocom back to Cyprus for repair, don't know if it is capable of the 'pump learn' function but I'm not expecting to see it again for a couple of months. Looks like I'll have to shell out to someone to do this bit, I hate surrendering the vehicle to others to have work done as I usually end up doing it again myself anyway. Took it to the nearest LR dealer when I bought it and the mechanic didn't even know where the fuel filter was.

    I got a message from Colin from Nanocom regarding this issue, and unfortunately it's not possible on the 2.4 engine, however i think it may be on the 2.2.

    I bought a Faultmate II from BBS, would have got a Nanocom but they can't do the pump learn.

    Alright so took her in to get the fuel rail pressure tested, it was reading 23,500 K Pa at idle which is apparently fine?

    I just bit the bullet and purchased a new Denso valve from a fleabay seller for $175 which I think is very reasonable, especially since the same valve from Land Rover is upwards of $400!!

    Will fit it and relearn the pump next week and hopefully my issue will be resolved!

    For anyone that is interested.

    I finally got the new SCV fitted and a relearn completed yesterday, and the issue seems to have been resolved!

    Car idles fine when cold or warm and there is a lot less white smoke. There is still some however on very first start on the cold morning, but it disappears when the engine warms up.

    I will post on here again if anything changes in the future, but as of now, I do recommend that anyone who is experiencing similar issues to myself look into fitting a new valve.

    All up it cost me about $350 for the part, installation and pump relearn.

    Thanks for the info Keath, who'd you get to fit/learn for you, LR or a private mechanic?

    I supplied the part and got Highbury Automotive in Burwood to install/ learn the pump as I have been there before and they are LR specialists.

    So I take it that the vehicle will run tolerably in between changing the valve and having the 'pump learn' performed? This has been putting me off doing anything as I thought the vehicle would be disabled. Mine is getting worse on these freezing mornings, cut out at idle 4 times this morning. I need to find someone who can do the learn thingamajig, still wondering if anyone can recommend a diesel expert anywhere from Dandenong to Gippsland?
