VCDS can definitely recode Motronic 7 ECUs (and others) - I've done it myself on V8s and TDIs. However, in order to recode it you have to log in to the ECU with a specific code. Only then will it accept the new code. There's nothing in the W12 documentation about logging in, which surprised me, but it may simply be an oversight.
I will have a look and see what the code is for the V8. As both ECUs are ME7.1 it might be the same on the W12.

Well i have found time to google about login to ecu. Now i need code to apply procedure,
Maybe code from V8 is same for W12 because they use 2 ecu module and same generation. If you can find your code to try loging in with that.

27 for Brazil...
Would that be for the ethanol content in their fuel? Min 25% up to 100% blends 😲

Forgot all about this sorry - I did look in Elsawin but couldn't find it, and also can't find my notes on the manual swap so I don't know where I found it originally.
It might be worth having a poke around on the Ross Tech forums?
