I was just about to check the rail pressure with the engine on, but the fkin battery ran out of juice. Would have ruled out the high pressure pump. Will check it tomorrow. Btw, i don't think diesel is getting into the sump - oil doesn't smell of it.
Not a clue about whether its been miss fuelled or not. Apparently cut out whilst driving on the motorway. Assuming it has been, then it would make sense that all 6 injectors are leaking (btw, is it correct that they shouldn't be leaking with just the ignition on?)
However, surely if it had been missfueled and the HP pump shagged, then it would refuse to start at all. If the HP can only generate 30bar at ~2/300 rpm cranking, then it wouldn't generate the ~300bar+ to keep the engine runing (with the help of easystart) and wouldn't rev up at all - its very responsive and eager to rev!
Symptom summary; Once started, as said, the throttle has to be pushed to keep it idleing, otherwise it cuts out. When warmed up, there is a noticeable miss but it isn't drastic or anything - possibly caused by thinner fuel making leak off rate greater... There is smoke if rev'd hard. The throttle is overly sensitive to the slightest prod maybe due to injectors overcompensating - yet injector mass adjustment values are fine
