Good Morning friends hope everyone is well. I have a MK7 golf tdi UK model. Both my outer rear/tail running light do not come on, only during braking do they light up and while braking if indicators are on, the brake light will turn and off same as indicator. This is not how they operate originally from what i remember.
I have a static fault code "U101400 - Control module incorrectly coded" so i know somethings not right. Ive gone back to my obd11 history and have undid the changes ive made but to no avail. There is also a reset option which i used on central electrics still no luck. What have i missed? Anyone can help me out. I would really appreciate it. Ive attached pictures and a video (sorry about the glare) for better understanding. Currently: imgur.com/a/pODqKXc Before my mess up:  
Thank you |

What country is this?
Post-up screenshots of Leuchte20BR LA71 and Leuchte21BR RC8. To be clear, I need to see the values of ALL 19 x channels for each Leuchte-set in your pictures

k138: haha...... definitely NOT a "legend" - I'm certain that you know lots of stuff about which I'm totally ignorant!
hmm..........no offense intended, but very odd coding indeed!! It almost looks like the coding for the brake lights on this car is from a "Yankee" Golf (but not quite)
Anyhow - the settings below will take the coding back to factory-values for a UK vehicle.

Cheers mate, that did the trick, changed all the values to match yours. Outer tail lights back to working as they should also fault code "U101400 - Control module incorrectly coded" cleared!
Glad im back to stock next time I'll make backup, lesson learnt.
Appreciate it Don.
