    I have been getting a P0234 turbo charger overboost condition.
    I had a friend look at it, and can not confirm what’s causing condition. Has anyone had this happen before? If so what did you do? TIA

    There are many reasons for this P0234 fault code to appear. However, the most common causes are:

    The turbocharger or supercharger wastegate is sticking or damaged
    Sticking wastegate control valve solenoid
    The wastegate control hose is clogged
    Defective or corroded connections or wiring to the boost pressure sensor
    Faulty connections or wiring to the knock sensor
    Bent rod from the discharge gate actuator to the discharge gate in the turbo
    Faulty turbocharger boost sensor or actuator
