The live data told us the Lambda sensor was working.
Emissions was tested on a crypton gas analysis.
The owner had a after market catalytic converter about 3 months before the mot, it is not a genuine citroen one.
Other parts fitted between mot fail and retest, they have also changed oil-plugs-air filter-petrol filter.
