walace58 Posted June 3, 2020 Share Posted June 3, 2020 I have a 94RRC registered September 1994. Every time is goes for MOT in the last few years it fails emission. Had a new cat about 4 years ago , but it eventually scrapes through after tweaking. As the p38 was on sale at the same time , I wonder whether the levels the mot station are given by DVLA system for the reg are confused by the fact there were 2 very different Range Rover versions? Does anyone have the emissions listing for the RRC and the P38? or any other comments? Thankyou Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted June 5, 2020 Share Posted June 5, 2020 Has anyone previously tinkered with the EFI system, maybe swapped the tune resistor for a non-cat one or something like that? Quote Link to comment Share on other sites More sharing options...
nkg Posted June 6, 2020 Share Posted June 6, 2020 Do you know which emission test it is failing on? My 1993 RRC LSE constantly gets close to failing the lambda test. Quote Link to comment Share on other sites More sharing options...
