Hi Jeff, i just came across your question and it seems i have the exact same problem. curious how it was resolved for u. For some time now my 2006, 244, 2,2HDI Boxer Van has stopped suddenly, randomly, or when stepping on the gas to pass someone, so often in unfortunate situations, like pulling a trailer through 20 km long norwegian fjordland tunnel, haha, so far i managed, never realizing hwat the issue was, suspected an air leak into some fuel line, because i had that actually b4 on this car and fixing the leak stopped the stopping problem. So now sometimes the motor just dies and the engine management light comes on , sometimes the light goes on and the motor just sucks into limp mode. a restart will reset until the next time. Now the vehicle has an added loss of power and exhaust gases come via the ventilation, up through engine bay into the cab, so something is definitely amiss now. and i suspect the turbo has perhaps given up. best regards from the Åland Islands of Finland, RObert
