Smax cutting out 50-60 mph

Hi,

I have a 2016 2.0tdci smax (auto). Last week it randomly cut out completely and after coasting to the side of the road I tried to restart but just turned over and wouldn’t start. After turning ignition off and back on it started instantly and I carried on my way. It now cuts out every time I get up to 50-60mph or if I put my toe down slightly at an incline and then starts after I turn off and back on. It drives fine if you take it very easy. Also it seems to be losing some water. I drained the tank, changed the filter and filled with fresh fuel but made no difference. A diagnostic check gave me four fault codes.

p008a21 fuel low pressure circuit. Pressure too low.

p025121 fuel metering unit signal too low

p008700 rail pressure-pressure too low

p228c00 fuel pressure regulation pressure too low.

Has anyone encountered anything similar, I have some further diagnostic work planned for Wednesday. TIA

    Sounds like injectors, I had the same issue and it tends to happen between 50-70 and under slightly more load then a flat surface (slight incline on motorway). It could also be the leak off pipes but that doesn't normally cause it to cut out.

    Some advice

    I would change all 4 if high miles, change the leak back pipe too, the brackets that hold the injectors in should be the newer model on your 2016 but if older i would change them at the same time.

    Buy any parts from Peugeot not ford if you have the 2.0 TDCI duratec

    Welcome!
    Your problem may not have the same cause, suggest you get your own codes (!😉) and come back with more info including history, fuel filter last changed etc etc.
    "WE" Do Forscan!
    Otherwise you are asking for random guesswork?
    Could start your own new thread as there are no solutions on this one (although there are a few suggestions with no responses?)
    You could change the injectors and all the other parts above if you are feeling lucky and rich?
    (Sorry for my feeble attempts at humour)
