Hi mark. Many thanks for your input. Always willing to learn. I don't know if running the engine at 2500 revs would mean I was in stratified load or normal load but the test in all mot stations are the same so it goes that the same results will be produced. Also the results from BMW the default limits were set as normal where they should have been set to .7 to +4. This engine will not pass at the normal default settings.If you look at the 16th edition of emission data it can been seen that this seems to be the only engine with this wide setting. I agree that we will see more of this type. My beef is the garage passed this vehicle by cheating. What do think of the explanation of the eml? Kind regards Les
