Reoccurring DPF fault, engine management light on and lack of power due to DPF blockage. Fault codes stored P242F DPF restriction due to ash accumulation, P2463 DPF soot accumulation, P244B DPF differential pressure sensor circuit high.
After further investigation the fault was found to be caused by a blocked DPF fuel vaporizer preventing DPF regeneration. The fault was cured by cleaning the DPF fuel vaporizer with Forté Diesel Intake Cleaner, removing the DPF and manually cleaning with Forté DPF Off-Car Cleaner as per instructions.

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.
