    Wasn't there a TSB for this "shaking" on the Gen 3, which involved fitting new manifold ?

    It'd be really good if OP comes back, with post dealership visit info; first report I can recall of 4th gen EGR clogging?

    This a Gen3 (2010 based off of her profile) in a Gen4 forum:(.

    So no such luck :).

    Still waiting for a 100 k mile super commuter to agree to the Gen4 egr circuit challenge(y).
