hi all, I wanted to know of info ,and is addressed to the pompisti or who I can give the info.I apologize for the data tomorrow if I can that year delivered the car to insert them. thanks for your attention and for those who help me.

I will tell you a little history of this car.
the customer complains of light engine on, and not makes,error in the ecu, dpf clogged,the customer decides to delete the dpf do the whole procedure emptying the dpf and recalibrating the ecu and closing the egr valve.now begin the problems the customer complains of a strong smoke black from the exhaust errors in the ecu, there are none and the car runs good makes good .making a diagnosis and looking at the parameters seemed to be all ok,then I recommended to close the egr valve with a plate, and still the problem remains ,at this point the council to try to change the washers of the injectors and I noticed that the thickness of the washers were 2.5 mm.
At this point the injectors original bosch 0445110351 euro5 95 hp with dpf ,I will have them replaced with bosch 0445110183 95 hp, euro4.when we tried the machine, the black smoke was almost gone not, it was almost more a only when an acceleration is strong, and then disappears.sorry if I was too long.
I wanted to know if these injectors that I have fitted in some way create some problem.
I forgot the injectors, the originals were already disassembled because sfiatavano the sealing washers ,the injectors were quite small evil,the pompista I said that they were to be reviewed.
