Mini Cooper R56 hidden engine codes, diagnostics, tools

Here&how to unlock the computer in your Mini Cooper in order to check for engine codes and a bunch of other things. I&list the things I know (or I think I know) and wherever I&wrong or unsure you can give your input. Sitting in the driver seat with the door closed and engine off, hold the trip meter reset button. While still holding this button, press the key fob into the slot where it goes. You should see VIN appear in the lower display. Let go of the trip meter button, and two letters followed by five numbers should appear. Add the number digits together (in the video, I add 7+7+7+5+3=29) Remember this total. Hold down the trip reset button again for about 3 seconds. When you release it, the 01.00 number in the square display should change to 01.__. Let go of the button, and then press and release it until the number goes up to 19.__. When it is on 19.__, hold the button for 3 seconds then release. The lower display should now read LOCK: ON CODE: 01. Press and release the button until the code number is your total from above. (in my case 29) Hold the button for 3 seconds, and the bottom display should clear, and the top display should go back to 19.__. Now you are ready to cycle through the numbers in the top display, from 01.__ to 21.__. At each number you will hold the button for three seconds then release to enter that section of the computer.
