your fuel injecters are dunping solid fuel hence the somkie unbernt fuel step1) replace fule filter step2) buy redex injection cleaner from a garage or halfords it says 1 bottol treats 2 tanks my methord mix 1 full bottol to 20 liters of fuel or 1/4 tank run engine for 10 mins so cleaner circulates though pump and injectors leave to sit for 30 mins and take it for a good run if this works disconnect air filter pipe from turbo and loer intercooler pipe on same turbo housing spry short blasts of wd40 into inlet on turbo with engine ticking over you will see dirty oil vapour coming from the intercooler outlet this will clean turbine blades and restore performance replace pipes and tighten clips so there is no air leeks. hope this is of some help
