Problem with a VOLKSWAGEN POLO 2004 1.4L 60K
Failing emissions test on idle CO 0.9% HC 250, catalytic converter, oxygen sensor, EGR valve
replaced and valve timing checked. Road test carried out and fault still present. The fault was caused by a faulty EVAP unit.
EVAP unit replaced and Forté Specialist Injector Cleaner added to clean the fuel system.
Emissions restored and vehicle passed.
