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.

 

Blank the egr off and run a forte turbo cleaner through it.
The turbos are variable vane and can soot up.
There is guides on you tube to clean them without removing! Mr muscle oven cleaner works well!
