Hi. I, too, am new to the forum and am the relatively content owner of a 2012 C4 HDi 1.6 exclusive in glorious Babylon Red. It's my 6th Citroen, but likely to be the last ...... Has anyone come across the following fault? Slowing almost to a halt in Auto mode at, say, traffic lights, and then moving away in second gear at low speed, but, as the torque comes up, the car changes down to 1 with a jerk and then moves off jerkily? It feels as though the engine is misfiring badly. The only 'cure' is to stop completely and then move off, when all becomes sweetness and light. Can be a bit un-nerving when in a stream of traffic, all of whose drivers are impatient to get to work! Also, is it possible to retro-fit electrically-adjustable front seats? Citroen say 'no!' (this in spite of the fact that the LHD version of the same model comes with it as standard)
