The coding in this guide worked for me on my 2018 US-spec 540d! The only hardware I had to install was the correct rear fog light switch. My tail lights had the diodes present and the left (driver's) side rear fog now works along with the indicator in the instrument cluster. The right side does not light up but I'm assuming they only ran the wiring for the driver's side because that's the typical set up for rear fog lights. Thanks for putting this together!
