New MOT testing rules and diesels

Mercury RV · 21st May 2018, 22:56

Evening good people, I took my newly acquired 75 diesel for a new MoT under the new regulations, the limit according to the data plate at the base of the 'B' post states 1.0, prior to the test I added a quantity of Wynn's injector cleaner, and then a fast run down the local dual carriageway. Once connected to the smoke tester, the result was 0.23, and this from a vehicle showing 120,000 miles. It is true we had also removed the relevant pipes and ensured that everything was cleaned very well, which also included the inlet manifold and MAF. Is this a normal figure in your opinion? Not sure if I have the re map carried out to 160 this Wednesday by young Phil T4 it will achieve the same result next time, still there are 365 days to find out and enjoy between now and then!!
