My preliminary observations suggests that it's all done with a set of 80 channels with the words "dimming_characteristic_curve_adjustment" in their description. So I have turned my attention to instrument cluster lighting. After much experimentation I think that I now have a reasonable understanding of how "Leuchte programming" works on MQB platform vehicles. My tweak is just something that I've been working-on for the last month-or, so. Worth a try if you are really keen I reckon because there is no other way to get these codes - short of industrial espionage! Uwe Ross on the RT forum suggested contacting commercial companies that reprogram firmware for these control modules ( ECU tuning, auto-transmission businesses etc). The ABS module certainly accepts the code, but that's all that it does! Could try randomly entering numbers, but a 5 digit number has 100,000 different combinations and the module locks out for at least 10 minutes if the wrong one is entered! The code 20103 works on a number of modules (I've just published a tweak that lights-up the instrument cluster during daylight hours and this security code works on 17- Instruments module). In the case of the ABS question posed in the opening post, I've had the same problem, without succes! So the only way that the general public gets to know them is by happenstance and word-of-mouth! Problem is of course that by their very nature, security codes are not published by VW.

For the other control modules (at least on our ROW models down here) it's a manual entry task- and then only if you happen to know the security code! The Fed: true, there is a pop-up ballon for the BCM on a mk 7, but I'm fairly sure that this is the only control module where this happens.
