I have a 2006 2.0 turbo diesel Recently I have had trouble starting the car, it turns over like it wants to start but does not. I have left it for the core plug light to go off several times then some time it starts with a ploom of smoke out of the back. The odd thing is when it starts doing it now I open the drvers door and try it and it starts first time!!! Can anybody help I thought it may be the imobiliser!!! Thanks
