How do i set the co2 level

CO2 levels are set by the ECM program. If the HO2S and O2 sensors are working properly then that information is relayed to the ECM ,checked against the CPU program and the air/fuel mixture/timing is adjusted by the ECM to rectify the readings. Run the fault codes to see if there is a sensor problem

Car has failed mot on high co2 emmisions

Have you had the ECM checked?

The ECM controls your fuel to air mixture as well as monitoring the CO2 levels.

Also, have you checked the oxygen sensor, when there's too much oxygen intake,,, the ECM increases fuel to compensate for the excess air, and thus results in more CO2.

Another check would be to find the diagnostic port, (usually under the dashboard), and, to either hire, or borrow an OBD diagnostic tool and see if there is an error code displayed, beginning with 'P', the code will show you what component is likely to be in error for producing the high CO2.
