Lack of power and engine management light (EML) on due to blocked diesel particulate filter (DPF), fault caused by a faulty EGR valve preventing regeneration of DPF.
The fault was cured by
fitting a new EGR valve and removing the DPF to manually clean using 2 x
Forté DPF Off-Car Cleaner as per instructions. The vehicle was then taken on
an extended road test with the vehicle power and performance restored.
Thanks to Michael at Kelly’s Garage in Byker, Newcastle-upon-Tyne.
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.
