Hi, this is my first post, I have a Mk3 Galaxy 2.0 Tdci Ghia (September 2006) I have had the car since December 2010. Over the last couple of weeks (four times) it has failed to start, turns over normally, seems like it starts then immediately expires. It starts eventually maybe after 10-15 times of trying. When it does start there is quite a lot of grey/white smoke at the rear. I thought it might have been the immobiliser at first, but the car wouldn't have started if that was the case I suppose. Could it be fuel filter, air leak or fuel starvation problems? Any help would be greatly appreciated. Thanks Ian
