Hi I posted on here about an emissions failure earlier. I have just taken my car back for a retest and the emissions are now fine. However it still hasn’t passed the test because it turns out that the engine management light never illuminates even on start up. The tester says it should have been showing up when I had a fault on the emissions. Anyone have any ideas how to trace the problem/fault to rectify this? Thanks

Hi again. I took the car for a retest today after having changed spark plugs and oil and adding additive. Emissions are now fine, however, it brought up a previous fault code P03033 which was still on the system although the engine check light was not lit. It turns out that the engine check light never comes on. The centre will not pass the car until I get this sorted. Any advice please?

Thank you I will pass that on

Hi my 2014 Micra failed its emissions test. No lights were showing but on checking got a fault code P0037. Mechanic changed both lambada sensors (not Nissan originals) and the emissions are worse! Another mechanic says it is probably because we did not use Nissan original parts. Before I spend even more money can anyone advice please. Thanks
