    N63 Low boost no codes

    Hey!

    Engine runs great, no oil burn, no codes, no missfires, good gas milage and its all good - but, boost is too low.

    Using the carscanner app I can only see 0.18 bar boost!

    Anyone seen this problem or have any clues for me?

    Thanks

    Do the N63 use the same boost solenoids as the n54/55? Might be the cause. Or if a vacuum line came off.

    Yeah , as far as I can tell they do, I just find it hard to believe that both are failing at the same time?!

    I’m gonna try giving the wastegate lines some vacuum to see how they operate.

    But isn’t zero codes kinda strange? Engine purrs like it was brand new, and I responsive , gas mileage is great and everything seems very good, except for the very low 0.18 bar boost ��
