Anyone falling this guide. I had the opportunity to scan a 2018 M240 curious to see what the voltage settings that were set for the lights and it turned out to be 100% 0x64 instead of the recommended 13.7v found in the guide. I'm sure you won't damage anything but anyone looking for an OEM coding this appears to be the answer and this is for all of the second part of coding where voltage is changed in this DIY guide.
