VOLKSWAGEN POLO 2004 1.4L 60K
Failing emissions test on idle CO 0.9% HC 250, catalytic convertor, 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 Specialist Injector Cleaner added to clean the fuel system, emissions restored and passed.
Thanks to Steve at Crescent Road Garage in Cowley, Oxford.
