Anyone got any ideas where to start to try diagnose this? Any help appreciated.

    Perhaps start by taking a look at "boost control position sensor A" ? 🤔

    Ah!

    The man who can most probably direct you to where exactly it is, is @TomsFocus. He will be back on the forum tomorrow morning 👍

    1.8 TDCI uses an electronic boost controller.  Small plastic box attached directly to the turbo.  I suspect the control position sensor is integrated inside this box.  Although that is not the usual code for when these fail, so you may find it is the wiring between this part and the PCM instead.

    Thanks for the reply. Would you be able to tell me where I would find this on the car? Is it accessible? Cheers

    It's about half way down the back of the engine so not the easiest thing to access.  You can just about see it in situ on this picture, just above gearbox height.

    Car went into limp mode again and wouldn't come out it so managed to find the actuator looks like a broken wire right at the plug its 5th wire, looks like an earth wire. Assuming that's the issue managed to jam them together see if it helped and car started and revved fine. Now to try and fix it looking like a new plug. Cheers for your help wouldn't have  a clue where to start.
