Problem with a SAAB 9-3 1.9 TiD 2007 134k

Lack of power due to engine running in limp mode, engine management and Diesel Particulate Filter (DPF) warning light on. Suspect DPF heavily blocked.

The fault was cured by removing the DPF to manually clean using Forté DPF Off-Car Cleaner as per instructions, carrying out an extended Forté Advanced Formula Motor Flush adding Forté Oil System Protector into the new oil and adding Forté Diesel Specialist Injector Cleaner and Forté DPF Cleaner and Regenerator into the fuel tank.

The DPF was then regenerated and reset using diagnostic equipment, showing 0% soot loading and taken on an extended road test with the vehicle power and performance restored.
