    Suspecting the anti shudder valve on my PD130 has a fault.
    There is no sign of the the actuator arm moving when turning the engine on or off. There is vaccum on the pipe when turning off, but nothing when starting.
    Should I be able to see movement on the ASV arm?

    Inside the ASV is a really thin rubber diaphram which had a big split in it. You cannot get a new diaphram from VAG only the whole EGR/ASV assembly so I used a mechanics rubber glove finger stretched over the diaphram to form a new seal. Cost me £ 0's
    Shut down is now instant & shudder has completely gone. :arco:
