    Hi all,

    We have a problem with our 2006 1.9tdi at the minute.
    It feels like the turbo isn’t kicking in usual 2k revs.
    If we carry on booting it up to around 4K revs, it often bails in to limp mode.

    I’ve run a scan on it today and pulled up the following codes.
    EGR system - P0401 - insufficient flow (had the light on a while for that one)
    Boost pressure regulation - P0234 - Limit exceeded (overboost condition) - intermittent.
    2 x cylinder glowplug faults
    3 x bulb faults

    Anything jumping out to any of you guys at all?
