In my opinion cut off problem occurs if engine is not getting sufficient fuel and/or air. Clean the air filter, turbo filter and fuel filter. Check the continuity of diesel flow from filter to hdi pump. If you haven't found any problem there then the possibily the hdi pump and injectors section needs to be checked. If the car has done more than 100000 miles then clean inlet and outlet manifolds including check of turbo and EGR valve. Do everything whatever possible before you take your car to garage. If there is no luck then let your car diagnosed and check any error code recorded by ecu.
yes these suffer bad on faulty turbos, i think yours is dead, let me know how u get on.
i know they carbon up inside which stops the oil getting in, really u need another oil change between servicing.
Hi, I have a 2.0HDI Expert which was doing the exact same thing as yours, blowing thick black smoke, sluggish and loss of power on gradients, a hissing sound and surging. I replaced the air flow meter but that didn't help. I was told to replace the turbo but a turbo expoert told me not to as it would blow white smoke if it was faulty. I was then told to replace the injectors but a diagnostic test showed them to be functioning fine. I was then told to look at the intercooler which had thick sludge at the lower left pipe. I replaced it today - Sunday 12th July and it is now driving like a new van. It now pulls me up gradients with ease in 4th and 5th instead of having to drop gear to get to the top. I got a replacement from Euro Car Parts for £147 inc VAT. To tell if this is your problem, look through the gaps in the lower section of the bumper at what looks like the radiator and look for sludge over the inside of the bumper and all over the pipe where it joins the back of the radiator (intercooler). Also open the bonnet and look down behind the grille for the same sludge. Hope this sorts it for you. Barry, Newtownards, Northern Ireland.
Injectors from the same ccm engine are most probably sounds same but to be on the safe side check not only the shape but code on the top of injector too. Because they are piezo effect injectors and set by the manufacture for a specific pressure for specific engine codes.
