    I know what the code is: manifold boost pressure/unknown root cause.
    2009 vn780 D13 485 Ishift

    This is what has been done to this point:
    turbo and actuator
    air to air pipe turbo side and boot intake side
    CAC
    exhaust manifold
    both bellows pipes between turbo and dpf
    resealed intake manifold
    engine harness
    both boost sensors
    egr diff pressure sensor and cleaned the venturi pipe
    reprogrammed engine ecu
    7th injector and w/forced regen (which has no problems in passive mode)
    overhead has been run a month ago with injector#3 and 6 cups
    no intake or exhaust leaks at this point visible carbon deposits, bubbles, or audible.

    I receive no check light when the fault occurs even though the manual says i should. The problem occurs while pulling grades loaded and empty. Oil temp will hit 230* and coolant 215* at which point i will start loosing boost pressure and truck will derate. Once oil and water temps come back to normal operating ranges the truck returns to normal operation with no problems.

    anybody have any ideas what would be causing this?

    As soon as I hit 600k I started getting issues sent it to Volvo late January picked it up two times 1st turbo was stuck on level 1 replaced that then head cracked in 3 spots. rebuilt didn't make it 500 miles oil shot everywhere. Then 3rd time I picked it up last week drive 300 miles or so oil and coolant started mixing
