    What are the codes? don't assume a fault code for a sensor means it is faulty...

    Yeah... fair point... these suggest both are not happy...

    17608 - Boost Pressure Control Valve (N249)
    P1200 - 35-00 - Mechanical Malfunction
    This typically happens when you have done an N249 bypass or if not you have a faulty DV

    Don't quote me but I'm pretty sure the post and pre work on different perameters, so are both different, I'm sure though someone can clarify!??
