Problem with a FORD FIESTA 1.4L TDCi 2012 41k

Engine management light on and fault code stored for turbocharger boost control performance. Suspect fault due to sticking variable vanes on turbo.

The fault was cured by adding Forté Diesel Specialist Injector Cleaner and Forté Diesel Turbo Cleaner into the fuel tank and the customer advised to run for a week using premium fuel.

After a week the customer reported there were no further faults and the car was running fine.
