Lack of power and engine management light on. Fault code stored P242F diesel particulate filter blockage/ash accumulation, suspect particulate filter blocked. Road test carried out to allow regeneration, exhaust temperature only reaching 380 degrees Celsius.

The fault was cured by removing the Diesel Particulate Filter and pouring 2 x bottles of 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 using Clean & Protect, 45 minute Advanced Formula Motor Flush adding Oil System Protector to the new oil and DPF Cleaner and Regenerator and Advanced Formula Diesel Treatment added to the fuel tank. The car was then taken for an extended road test to allow regeneration of the particulate filter, the exhaust temperature was rechecked reaching over 600 degrees Celsius, allowing a successful regeneration and restoring performance.
