The car has just passed the MOT but I noticed something a little odd. Using my car reg the lambda max limit on the test equipment was 1.03 but the official DVSA limit is 1.09. The engine was coming in at around 1.05 so was failing. I had a copy of what it should be so the tester entered all the specific engine details (1.8 VVC engine type RC) and it passed easily. I had the details with me because every year it struggles with lambda and thought it would be a good idea to arm myself with the correct numbers.
