Hi, i am having a bit of a nightmare with my disco4.
I have a couple of recurring dtc's P22D3-77 and P22CF-71.
I have had the car at a specialist that has replaced the secondary turbo shut off valve, smoke tested the system for leaks and are now suggesting that it needs a whole set of elbow pipes that they think are collapsing on acceleration.
suggestions would be helpfull
thanks

Hi Paragone,
Did you ever get to the bottom of your issue? I'm having the exact same fault codes on my Disco 4. I've had the vacuum system checked and there's no leaks. I've also checked the comp/air re-circulation actuator and that's functioning fine so think it must be a sticking actuator on the secondary turbo. Just wondered if you had anything else I can check before biting the bullet and getting the actuator replaced?
