Hi I have a 1996 306 D-Turbo When starting from cold It's as if the engine mis fires, I sense a "juddering sensation when it`s idle" It disappears when the engine warms up, The car is up for a service in Feb 2004 so It will get an air filter and fuel filter change but does anyone know of what this problem could be? I have tried different types of diesel from garages and it still does the same, It only does it when Idle and not when driving down the road etc. Anyone have any ideas please? Thanks Pete
