Hello Friends, I have a RRS TDV6 3.0 245hp of 2010 with 62,000 milles and when i go to 100-110 km/h ( 60-66 milles) keeping the accelerator pressed very soft i get the fault of restricted performance. The car is put into limp mode and i have to stop and turn on and the fault is removed. The machine gives me the fault P2263. That may be the problem? Change for some time the actuators shut off valve but the problems remain ...



In the diagnostic machine : P2263: regulation valve turbocharger boost pressure, control circuit signal amplitude very large upper





Help please ! Thank you very much

Workshop manual gives the following as possible causes:

Air leakage post
turbocharger

Intake air
temperature (IAT)
sensor circuit high
resistance, short
circuit to ground,
short circuit to
power

Manifold absolute
pressure (MAP)
sensor circuit high

Mass air flow (MAF)

Exhaust gas
recirculation (EGR)

VGT actuator failure

Turbocharger vanes
stuck/sticking

Not sure if that's helpful or scary...  2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Thank you very much !!!!!

I have been told that the fault comes from the turbo actuator

Morning give me the car
