Re: Intermittent P2263
An internet search finds the following possible causes.
P2263 NISSAN Possible Causes
Intake air leaks
Exhaust gas leaks
Faulty Turbocharger boost sensor
Faulty Turbocharger boost control solenoid valve
Faulty Recirculation valve
Faulty Exhaust manifold and turbocharger assembly
Faulty Boost control actuator
Since Darryl found a split in his intercooler inlet hose, then looking at all your flexible hoses between inlet and manifold would be a good place to start. Then check all clamp fittings are tight and that there are no exhaust leaks before the O2 sensors. Next I would suggest checking all sensor connectors.
Not being an actual diesel Xtrail owner, these would just be my logical check points to start with based on others experience with this fault.
