18:45 的 Poeppi Hello I have an Opel Vivaro 2.0 cdti And despair straight. At cold outside temperatures the rotational number fluctuates and it goes off. Only with warm engine it runs quietly! Above all it runs restless if it has stood longer. Battery, glow plugs and diesel filters have already been changed! Does anyone have any idea what that could be? Even my screwdriver desperate! Helpee I would like to put in a video but don’t know where??
