Lack of power and engine running in limp mode due to blocked DPF, unable to carry out DPF regeneration.
The fault was cured by removing the DPF to manually clean using 2 x Forté DPF Off-Car Cleaner, soaking overnight, rinsing with hot water and drying, 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 and taken on an extended road test with the vehicle power and performance restored.

Forté's Technical Helpline receives over 300 calls per month. This blog shares solutions for garage workshops on common driveability concerns that can be quickly and effectively treated. The vast majority of those identified are caused by fuel and oil borne contamination formed by natural degradation or via the combustion process. This is a fact of life for internal combustion engines where fossil fuels and oils are used.
