No power over 30 mph and EML on, fault codes stored for faulty glow
plugs, throttle body and DPF blockage, new DPF only fitted the month
previously.
The fault was cured by replacing the glow plugs and throttle
body, removing the inlet manifold/swirl flaps and manually cleaning
with Forté Diesel Intake Cleaner. The DPF was then removed and manually
cleaned with Forté DPF Off-Car Cleaner as per instructions, carrying out an
extended Forté New Generation Engine Flush and adding Forté Diesel Specialist Injector Cleaner and Forté DPF Cleaner and Regenerator into the fuel tank.
The vehicle was then taken on an extended road test with the vehicle
power and performance restored.

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.
