    P02CB00 fault code, limp mode

    Transporter 2011, 2.0 biTdi 4motion CFCA engine. 171000 miles.

    Had dpf light and coil light come on whilst driving to airport (150miles). Limp mode.

    Had vw roadside assistance come out, ws blocked dpf filter ( and dpf pressure differential sensor pipe), turbo pressure too low. Fault codes p02cb00 and P246300.

    He cleared pipe, tested G450 sensor, manual regen of dpf. Has new MAP sensor.

    It cleared the dpf fault but the low boost still returns after about 1/2 a mile.

    Full auto scan

    Was thinking it could be clogged up wastegate with soot or issue with wastegate actuator?

    Gonna try and get under van today and check both actuators move from end to end using
    hand vacuum pump.

    Whats your thinkings?

    I can't help with your issue I'm afraid, but as a side-note you should update VCDS. There were some bugs in 19.6.0.x

    19.6.1 has been out since late June / early July
    Apparently I should put something witty or profound in here.....
