    This is a Lhd model from middle east country.We are trying to get the car thro SVA test but is slightly over the limit on CO emissions.Diagnostic live data shows all 4 lambda sensors at default .42 volts.Further investigation shows that there are no lambda sensors fitted and never have been .The bosses in the exhaust are factory blanked as are the the wiring connections for the lambdas on the engine wiring harness.(car does have cats)I can fit 4 sensors ,but something tells me this may not be the complete answer.Any thoughts on this?
