I Have a Adam and have a orange steady fault light showing, symbol of a engine, and according to the hand book means "Emission control system fault emission limits exceeded", a independent large looked at it and replaced 2 sensors, but this did not solve the problem, they then took the car to a main Vauxhall dealership, they also replaced the same two sensors and the fault is still there, a week later they say they are still looking into it, any ideas?
