    Hi all,
    My Avant 2.0 TFSi makes a kind of slight "chatter" after changing gear at low revs, its after i change gear and re-apply the throttle and only lasts about a second. It doesnt happen under hard acceleration, only when driving at low revs. Is this perhaps because the diverter valve is not doing its job properly? It hasnt always done this, only appears to have been the last few weeks.
