LED rear lights retrofit what coding are people using?

Byte 18 set to 04. Mine fitted as standard rear leds and retrofitted led bi xenons. Did change byte 19 tho as that regulates the voltage to front and rear lights. Byte 19 is currently set at 86 from 00. Did do a spreadsheet with varying codes on many cars to see what the problem was with my bulb error and most cars are set to either 04 or 00. I did have VCDS and still can get access. It was the latest release and did have many options on a drop down menu.

Im told 00 is just a cover byte, its actually meeningless, its used to hide the true value.

Im told that as well. Forgot but someone mentioned the Kufatec dongle. I have one in a bag somewhere. They say on some forums that this actually codes byte 18 to 00. I never connected it as when i contacted them you never got a straight answer!
