    Looking at the Ross-Tech Wiki, the fault code is

    19561/P3105/012549 - Valve for Intake Manifold Flap (N239): Open or Short to Ground
    Possible Symptoms

    * Engines shakes at shutdown

    Possible Causes

    * Wiring Open Circuit or Short to Ground
    * Valve for Intake Manifold Flap (N239) faulty

    Possible Solutions

    * Check Wiring for Open Circuit or Short to Ground
    * Check Valve for Intake Manifold Flap (N239) > Output Test

    So I would check the to the intake manifold flat and also do an output test using vag-com.. here is a link with more info from TDIclub
