Problem with a ROVER 45 2.0D 90K

Failed emissions test at 3.89m-1 plate value 1.03m-1.

Emissions reduced by carrying out a Forté Power-Clean Diesel Injection Clean, Forté Diesel Intake Clean and cleaning through the intercooler manually with Forté Valve Cleaner.

Passing the emissions test at 0.58m-1.

Thanks to A and S Electrical in Bristol.
