Engine cutting out and excessive black smoke, EML on fault code stored 407E EGR fault.
After further
investigation, the EGR valve, EGR pipe and inlet manifold were removed and found to be heavily blocked with
soot deposits.
The fault was cured by fitting a new EGR valve, manually cleaning the inlet manifold and EGR
pipe with Forté Diesel Intake Cleaner adding Forté Advanced Formula Diesel Treatment to the fuel tank and carrying
out an extended Forté Advanced Formula Motor Flush. The vehicle was then taken on an extended road test with
the vehicle power and performance restored.
