Problem with a Ford Fusion 1.4 TDCi 2004 123k

Failed diesel emissions test due to excessive black smoke. No fault codes stored or faults found.

The fault was cured by carrying out an extended Forté Advanced Formula Motor Flush, adding 2 x Forté Advanced Formula Diesel Treatment and Forté Diesel Turbo Cleaner into the fuel tank and carrying out a 30 mile road test.

After the road test the black smoking was cured and emissions retest passed.
