Edit: Not sure if this should be the very first line here, but if you decide to do this make sure you get a 315Mhz BCM, if you're in North America. It was suggested to me that that didn't matter because there is an adaptation channel to choose the frequency. I went with a ROW spec BCM. Found that the key fob didn't work and thought it was a pairing issue. Turns out it only worked when held a couple inches away from the BCM, discovered by @xabhax. NAR spec BCM solved the issue.
So it is generally known that facelift Mk7's (and other facelift MQB cars) have a BCM with no long coding. While there is plenty of reason to upgrade to a BCM High (support for heated seats, fog lights, etc.) there isn't much reason for retrofitting a facelift BCM that I can think of, beyond wanting RGB ambient lights. The common belief is (was) that pre-facelift cars do not support RGB ambient lights. That is not entirely true, as discovered in my thread here. My pre-facelift BCM does support RGB ambient lighting, but in a very limited way compared to facelift cars. I updated the first post over there, but will add more detail of the limitations at some point.
Now moving back toward the target here... but a quick run down of concerns (this list might grow):
I will, in the first few posts, probably experiment with some different formatting to show pre-facelift vs facelift adaptations. Where the adaptations have the same IDExxxx-ENGxxxxxx numbers with same/similar descriptions I may not always include translations (because laziness). Where the difference is only IDExxxx-ENGxxxxxx numbers I will somehow indicate that but probably won't translate much. I will have to figure a way to clearly indicate when a channel exists in one map but not the other. And finally I intend to add translations and descriptions (as best I can figure out, but with community help as well) for those channel groups that replace functions previously configured via long coding.
Finally, this will be a slow process. I've got a newborn at the house and I've got the facelift BCM on my computer desk so getting this done is not an urgent matter.I'm not going to go through the trouble of reserving a bunch of posts as this project will not be quick. If anyone has any format suggestions please post an example. Ultimately I want this to be easy to decipher. Even after I start making posts with formatting, I will go back and edit if/when a more clear format is suggested. It may turn out that a Google spreadsheet makes the most sense for this, but we shall see.
Edit: As I thought more about this it occurred to me that I should reserve a few posts for the following reasons:

Now moving back toward the target here... but a quick run down of concerns (this list might grow):
- Many of the adaptation channels have the same IDExxxx-ENGxxxxxx numbers and descriptions... easy easy
- Some of them have the same IDExxxx-ENGxxxxxx numbers with similar descriptions... also pretty easy
- Some have completely different IDExxxx-ENGxxxxxx numbers, moving them to a different place in the channel map but still with the same/similar descriptions... not too bad
- Each has channels that look to be about the same thing but are in different groups... okay, Google translate helps here, helps always really
- Lighting control, which was once in Leuchte channels has been moved to a couple long byte strings... see here for details.
- So I will be converting my Leuchte channels sets to corresponding byte strings
- Facelift headlights moved lots of control to lighting control modules (LCM), this is beyond my "work scope" as I have halogens (now Osrams, but same thing to the BCM)
- All the long coding is now in adaptations, so Google translate and then some experimentation
- Lots of channels that exist in pre-facelift but do not (in an obvious way) exist in facelift, and vice versa... Google translate will again be your friend

Edit: As I thought more about this it occurred to me that I should reserve a few posts for the following reasons:
- This will not be a definitive DIY (a-la a @golfdave thread) because I will, for the most part only be focused on what it takes to retrofit a facelift BCM into my car. That isn't to say a lot, or even most, of it won't apply to anyone doing it but I feel it would be wrong to suggest otherwise.
- I think it best to have a couple posts up top that show (with pictures, to be added) the current long coding options in my BCM and the sub-modules of the BCM (in my car these are wiper control module, rain/light sensor, anti-theft alarm sensor, and alarm horn)
- My car has several retrofits, mods and other coding tweaks (found here and elsewhere) that I hope to maintain through this retrofit. I will try to list these in a post, as I remember them. It's very unlikely I will link where I found each tweak/coding change/etc... but I know that I'm taking zero credit for discovering any of these. I'm just listing them to be thorough in this thread.
- There should be something up top with a starting adaptation map of my BCM and one of the BCM I'm retrofitting.
- Probably reserve one more post, just in case
