Case study
2015 Volkswagen Golf
REAL WORK. REAL RESULTS.
Diagnosis Process
Further testing confirmed the noise was originating from the turbocharger actuator assembly. The actuator motor was not operating correctly and internal gear wear was causing a distinct rattling noise during start-up.
To confirm the diagnosis, the actuator assembly was removed and bench tested.
Carried out an inspection of the engine and turbocharger system to identify the source of the start-up noise.
Fault Found
The turbocharger actuator was found to be faulty, with worn internal gears causing excessive noise and preventing correct operation of the actuator mechanism.
Repair Completed
Due to the actuator’s location, significant disassembly was required to access the turbocharger assembly. Replaced actuator and adjusted voltage settings.
Outcome
Start-up rattling noise eliminated Turbo actuator functioning correctly No fault codes present after repairs Vehicle passed final road test and diagnostic checks
