Hi Guys.
I'm gradually working my way through fixing fault codes on my Discovery 4. Got 2 codes which are boost related that i need to fix
P2586. Turbo boost control position sensor B circuit.
P004A Turbo boost control solenoid B circuit open.
I'm assuming P2586 is probably a secondary result of P004A open circuit. I can't find much info relating to P004A and where I should start to look. Could someone tell me if this is related to the VGT turbo actuator on the Left hand turbo, or the valve on the back of the Right hand turbo or is it concerned with the CSOV valve mounted on the bottom of the Radiator assembly.
Any help would be useful
Thanks
Oz

Hi OZ,
Did you get to the bottom of this fault?
I seem to have the exact same faults.
