    Have 09 auto 177hp n47

    Got a remap and all was grand....until it went into limp mode...i checked for codes and its turbo actuator malfunction.... Went back to remap they flashed back stock but the code is there... No more limp mode at all...

    Now question.... Anybody kind knows if its possible to replace the actuator only? Some says that it will calibrate itself some says it can not be replaced....

    Does anyone know? Please....

    Ps: car is not down on power on anything just throwing the turbo actuator code fault...without obd reader i wouldn't notice anything

    Code is 449A

    Try a turbo actuator calibration with the diagnostics (your diagnostic might not be capable depending what model it is)

    What do you mean by not possible? I have done many adjustments using ista and similar.

    You can replace the actuator no problem but you will need to do this adjustment afterwards anyway, when the car was flashed it lost its adjustment setting for the actuator, that's why it didn't fix it when the old map was out back on

    You need to get the car on proper diagnostics (a high end launch, autel, thinktool) or else on the BMW software and do an actuator calibration
