Hella's Turbo Actuator is used on Garrett turbos. The Garrett turbos are used by almost all major European car brands. In the event of a defect to the turbo actuator, the car has no or less power at its disposal.
The fault can be found during a test drive. The stored fault codes can be read with a diagnostics scanner. The most found fault in the actuator are loss of power and a partially or complete failure of the turbo. Vibrations can create loose connections on the PCB. It can also happen that the VTG blades are stuck. This causes extensive wear on the gears and rack in the mechanical part of the turbo actuator.
When removing the turbo actuator, the regularity of the VTG adjustment must always be checked. If this is stiff, this must be fixed before the remanufactured turbo actuator is reinstalled. When installing the reconditioned turbo actuator, it must be coded in accordance to factory instructions. The normalization of the VTG adjustment must also be verified.
If the actuator malfunctions, the turbo will not function properly and the engine will not be able to perform optimally.
Failure to repair a turbo actuator can cause turbo damage and even engine damage.
The turbo actuator will undergo an Entry Test upon arrival, during which the operation and all functions of the turbo actuator are checked. If the fault submitted by the customer has been found, the turbo actuator will be remanufactured. The remanufacture process consists of an electronic and mechanical part. The electronics will be remanufactured and the actuator will be fitted with a new mechanical part, the so-called "gearbox". At the end, the functional End of Line (EOL) test is performed to check if the faults have been resolved and if the turbo actuator is functioning according to the manufacturer’s specifications.
