Hi to everyone this really is my first post and on reading through some of the problems people have so was hoping someone may be able to help me asmy son does all the getting underneath the van i just hold the spanners,
i bought a 2012 fiat ducato 2.3 130 multijet (for camper conversion) after i bought the van i noticed a oil leak, and when travelling down the motorway black smoke so the turbo charger was renewed as the oil seemed to be coming from the oil feed pipe and the fins inside turbo were loose. anyway oil has stoped leaking, the van now starts ok drives like a rocket, but on startup i get thick white/grey smoke it clears after 5 mins or so then i take on a run and black smoke when changing gears, i have cleaned air intake renewed the broken i think its a air sensor (bosch on air intake manifold) renewed air filter and cleaned pipe, cleaned the egr cooler and pipes and checked egr working
now when i unplugged the mass air flow meter below the air filter engine starts no smoke (grey/white) and when i take out for a run
theres no black smoke, so renewed bosch mass air filter (0281006048) and it made no difference so i unplugged it again van started took for run
again no smoke ran like a rocket stopped at shop for half hour or so started it up again all ok so left unplugged and drove home, i went to start it today and lumpy start and no throttle plugged sensor in starts with grey/white
smoke and full throttle again, all the throttle body was removed and cleaned when turbo was replaced and flap seems to move ok
so any ideas please.
