@marttimat:
Here's an interesting thing for you to try : I'm not sure what web browser you use, but whatever it is -invoke the find facility and search for the term "Brake" within the Leuchte-sets in your admap.
I can see in your admap that you have implemented the changes that you describe in post #39 (the "adjustments"). However, the ONLY instance of the Leuchte-command "Brake" (Lamp) in the entire 665 x Leuchte channels is ENG116958-ENG116293-Leuchte22BR MA57-Lichtfunktion A 22 - which is the high-level Brake light. This means that none of the Leuchte-sets in the tail lights is currently programmed to operate as a Brake-light - which is most interesting!!
Now, I've never seen an instance of an active physical car that has Leuchte-sets with no Brake light function (albeit I've generated this bizzar outcome on my MQB test bench). Intuitively, I would have expected that the Brake lights would not work at all (not even with a Brake pedal push). But, I am aware from my test bench scenarios, that the brake lights are intimately tied to the ECU and they operate when aspects of the hex01 module are missing. My hypothesis (guess really) is that this "special" brake relationship is an inherent safety feature of MQB platform vehicles - which (if correct) helps to explain why your brake lights work on pedal push - because they shouldn't work from a Leuchte-command perspective!!
So, why has this happened and what to do? Well... more than happy to be corrected if anyone has an alternate view, but I suspect that the instructions in your post #39 do not apply to the factory settings in your BCM.
As a way forward, it might be useful to post-up yet anther item of information; the history records that contain the "old" values of the channels that you changed as per the instructions in post #39. You will find these records in the file called AdpLog.CSV which lives in the directory C:\Ross-Tech\Debug. Perhaps place a copy of this file on a third party hosting site and include a link here.
