Problem with a AUDI A3 1.9L TDi 2009

AUDI A3 1.9L TDi 2009 52K

Lack of power and engine management light on; fault code stored for camshaft sensor fault. Further investigation revealed a worn camshaft and hydraulic valve lifters which were replaced. After the engine repair, engine would not rev up. Suspect fault due to a blocked DPF.

The fault was cured by removing the DPF and pouring Advanced Formula Diesel Treatment into the Diesel Particulate Filter, soaking overnight then rinsing with hot water and drying with compressed air. The vehicle was then treated by adding DPF Cleaner and Regenerator and Advanced Formula Diesel Treatment into the fuel tank and carrying out an extended road test to allow regeneration of the particulate filter.
