Lack of power and engine management light on, suspect diesel particulate filter blocked. DPF checked on diagnostic machine showing filter blockage 200% and fault code stored for EGR valve fault.
The fault was cured by replacing the EGR valve, removing the DPF and manually cleaning with 2 x Forté DPF Off-Car Cleaner as per instructions, adding Forté Diesel Specialist Injector Cleaner and Forté DPF Cleaner & Regenerator into the fuel tank. The vehicle was then taken on an extended road test with the vehicle performance restored.
Thanks to Quarry Service Station in Houghton-le-Spring, Tyne and Wear.
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.
