    They don't have a dump valve as such.
    It's the variable vanes aka the vnt in the turbo moving position in response to request for less boost or foot coming off the accelerator pedal in a fast gear change.
    I believe mapped tdi may be more prone to this as some maps have more boost lower down the rev range.
