My Plus8 is having an MOT next week. It has consistently been borderline on Lambda at top end when delving through previous owner MOT’s. However, checking the old MOT cert from last year it states limit is 1.03. In the DVLA website the emissions doc ( version 19) shows in the annex that Morgans have an upper limit of 1.05. The car passed last year with a reading of 1.03. I will wait and see what the test shows.
Question for an MOT expert...how would the emissions testing machine be set up to deal with the higher end Morgan limit? Can it be preset or a manual adjustment made if >1.03 is found?
It's all a bit unclear. My Roadster with a K&N was always right on 1.03, but it was never a problem because I know the tester over many years. I printed the page off just in case there was a query, but he was relaxed about it. With the standard air filter, the lambda drops below 1.03.
