Ok folks headscratching time. I bought my Mondeo st tdci back in January from a dealer ( well almost-Arnold clark) . it always had hesitation issues as it came on boost,after months of fighting they finally replaced the egr valve,cars better but far from right,now been informed it needs a new turbo,yet it had one last july from ford ( receipt in glovebox for a grand). now they are looking back its history and it`s had 3 turbos in as many years and now this will be it`s 4th.


Anyone else seen this issue and found a cure I can throw at them? cannot be low oil pressure or it would have killed the engine,doubtfull of split pipes/intercooler as it boosts cleanly once you unplug the egr valve .


I`m thinking possible injector issue causing an excess of soot or similar type problem that's fouling the turbo and failing it somehow?


cars standard no k and n filters,fancy exhausts or remaps.


at a loss here as I do like the car but now want to throw it straight back at them and demand a refund.
