but this vehicle was serviced at the dealer -- one would hope they could properly change the oil?
I don't think anyone is really going to be offended. I wish I could find the posts of dealers that have screwed up simple oil changes, but the search feature here is poor. Several on this board have had dealers put gasoline rated oil instead of the required synthetic oil in it. Others on this board have had dealers put 12 quarts of oil in it (capacity is 6.4). The dealership figured it must be a Cummins and have a 12 quart capacity... Still others have put 15w-40 non-synthetic diesel oil in it, which is what goes in Cummins but which is not what DCX says to put in this thing (0-40W or 5-40W synthetic only).
The air in the lines happens because this is a suction system. A small leak can develop in a hose fitting somewhere-- and it does not let fuel out, but lets air in. When enough air is pumped into the line-- the fuel air mix becomes "foamy" like a soda. The engine runs bad (has no power and shudders) or will refuse to start. This will not leave the vehicle f.o.r.d. (found on road dead) as you just open the bleeder valve and purge the air from the line by priming the pump until fuel exits the bleeder valve instead of air. Then close the bleeder valve and restart the motor. In really rare cases, a malfunctioning fuel heater switch has caused the fuel filter assembly to leak slowly, but no fires have been reported.
More than likely the air leak in this CRD is the fuel filter assembly/unit or is caused by the fuel being overheated (bad fuel heater switch), which areates the fuel. The dealer might have replaced two sets of lines for nothing, because they cannot troubleshoot-- just read codes. That would not suprise me.
The fact that this thing has had so many EGR's points to the same lack of competancy. The flow control valve or computer was probably bad and it kept wearing out the EGR as a result. Since the dealer monkeys can only read codes and are not smart enough to diagnose anything--they swap parts at DCX's expense and now this thing has had a turd load of EGR replacements.
Since that part was always back-ordered a year ago-- the thing was always waiting for EGR parts and the previous owner had enough of that and sold/lemoned it.
But as for the vehicle, nothing is wrong with it that cannot be fixed... but not by that dealer. If you want one... buy it and service it elsewhere.
