http://www.bba-reman.com/forums/Topic87926-1-1.aspxPrima pagina a topicului deja are o gramada de informatii. Nu m-am mai uitat la restul. Mi-au atras in special atentia urmatoarele postari:
"P0191 - Fuel Rail Pressure Sensor Circuit Range/Performance.
That code is in no way an instruction to change any component. It indicates that the rail pressure was reported as being outside the expected values.
Guesswork will get you nowhere on a complex system like an HDi. Either you know them - or you leave them be.
When you get that code on an HDi you carry out an injector leak-off rate test - the results of that are the next crucial bit of info."
"From the info you have provided i would be guided to the seized in injector. as the corrosion builds between the injector and head, it tends to have a compressing/squeezing effect over the most critical area which houses the spray nozzle, because the working clearance in the injector is so small any change in size can cause the injector to malfunction. now comes the bad part, on many alloy head engines the corrosion that forms in the aforementioned area is equivalent to it being permanently welded and many times the head or engine has to be scrapped. there has been a release of heavy duty injector pullers for sale, if the injector wont move with a couple of swings with one dont waste time, start looking for a head or engine. there have been many suggestions ref using coca cola etc forget it ive tried them all and none work. i also had one head where i had the injectors spark eroded out but that cost £200.00 more than a new head from main dealer !.
