ok i cleared the fault, and went for a drive until the engine faulted again, same code, 0707, except this time it did not go into limp mode.

My Turbo Actuator Rod by accident :icon_bonk: when the exhaust system was changed....not the fault of the car at all.Quote:

The manual says that:
Injection control system does not function properly. It is a feed back system, so makes adjustments and then needs to see the changes. It could be a wiring fault, pump or pump ecu fault, poor fuel quality or restricted fuel supply system.
Check your Fuel Filter also, to see if this is OK, as it may be partially blocked which causes this fault....

ok so after a few days of phone calls i have some new theories to check when i return from work. an injector pump specialist said that the 0707 fault can often be caused by injector lines being loose and sucking air (apparently a pretty common thing with the patrols) and also told me to check the return line to the pump (it runs through the manifold apparently????) also 0707 can be tripped by the crank sensor so if anyone has any idea about the crank sensor and where it is and how to check it and clean it if necessary? i would much appreciate that.
also after talking to the mechanic for a while the only symptom he has to suggest my turbo needs replacing is the fact that the leak coming from the intercooler was an oily residue, i spoke to MTQ in malaga (turbo specialists) and they have said that the fact the engine is not blowing any smoke then he doubts the residue is from an internal turbo seal, his reasoning was when a car is doing 3000rpm the turbo is doing about 20000 so when things like that go wrong with the turbo you will definitely know about it.
outcome at this stage, check injector lines, and crank sensor, if fault still occurs i will take it to mechanic to check for faulty wiring and anything else they may suggest. then i will fit pyro and boost gauge and monitor, fit catch can and monitor, fit dawes and needle valve and monitor, and to top it all off fit the cross country intercooler i ordered today and see how that all travels.
also i have another question, what is the container that is underneath the air intake pipe that is attached to the air intake on the outside of the pipe in between the MAF sensor and the crank case breather return? it looks like the solenoid that the boost control system bypasses is mounted to the outside of it??????
UPDATE***** for anyone that comes across this thread in the future for a similar problem...
so i took the car to Robson Brothers 4x4 (absolute professionals that know what they are doing, and ask so many questions to get an idea of what was going on. im so happy with them, their service, and communication)
they nit picked through the engine, and came to a conclusion it would need a new fuel pump, but knowing it had only been replaced 10000km previous they looked further and wider for days to try and find something else. they ended up changing the oil filter to a genuine nissan filter, and also found allot of oil in the ecu connections, they then went through all of the connections replacing some, and cleaning all of them after an oil leek problem had wreaked havoc on all the connections. so now the engine is pretty much sweet, i just need to replace the intercooler due to holes in the core from the engine cover vibrating on the intercooler. so bring on the cross country cooler.
Good to hear that's the problem has been found mate........ I've heard nothing but good things said about Robson Bros. If I had the dough, I'd just take my GQ to them and say, knock yourselves out fellas get it all spick n span
