    Default Turbo wastegate

    My 3008 has a system fault which has been traced to a wastegate problem. Getting the Turbo repaired will mean several weeks without a car. Does anyone know where I can buy a reconditioned or re-manufactured turbo? Prefer a local resource. Also any suggestions on good mechanics (turbo specialists) to get the turbo replaced.

    TIA

    Is your car engine a turbo 1.6?

    Have a chat to a diesel service place. They usually do mainly heavy engines, but there are plenty of cars about now. Out your way I know of Precision at Wetherill park, and JC Diesel at Narellan. I have not used either so can't give a reference.

    The wastegate itself is a pretty simple swing flap that opens when required to allow exhaust gasses to bypass the turbo's turbine wheel and limit boost production.

    Mechanically the wastegate is really bomb proof.

    The bit that usually fails is the actuator (which opens the flap) and is cheap and pretty easy to replace (usually).

    The actuator is usually connected to a boost referenced source (if mechanical) or controlled by the ecu if electronic.

    What symptom is the car displaying? No boost or too much?

    Its hard to tell. Perhaps it is a bit of both depending on the speed. What I know for sure is that the fault occurs at higher speeds (highway 100 kmph +) when the car encounters a slope. Much like the F3 (M1) in Sydney going towards the central coast. It is embarrassing when a humble Mazda 2 can easily overtake a turbocharged car! So there is not enough boost I would say. The car does behave a bit funny at lower speeds as it tends to jerk. The radiator fan stays on after the engine has stopped even after shortish drives. It does cut off after a few minutes. The car was professionally diagnosed and seems to be a common problem.
