So, should I see XDWA on the menu? have you retrofitted xdwa?
whilst I agree help pages / how to info is harder to find than I think it should be - there are some hidden gems about.
I have not tried to fit the later alarm - but in general the way BM go about things doesn't change, is not clever or indeed complex - its just a few little understood bits of fun to jump through - that said things are changing - From late 2025, the bike's are now unmanageable for retrofitting some toys - they have removed access for playtime on the newer stuff - and only direct contact online with base can allow you to get at modules the way you could on the older bikes
Re XDWA I expect the stumbling block you are having is with the VO list not showing the new option you want to get working - VO = vehicle order - is a list of toys / options on the bike at build - when its all aligned across associated modules, it allows canbus comms to make things work / or behave correctly.
Very few tools ever allowed you to get at or add modules to the VO - indeed if BMW ever plug it in to programme / update it will wipe the VO back to the one matching their records - and then the real fun starts - as they start programming the wrong software to the wrong module and it crashes out confused - and will remain confused till the toy is removed and the bike put back to std - or their VO records are updated with that option.
Often retrofitting at a dealer involves a long awkward chat at the parts counter ordering the option - you buy the right to have the toy on your bike - effectively paying for the software licencing rights and overnight BM update their VO records - meaning next time its plugged in it lists the bike as needing an i-level software update (integration level). First thing it does is flash the new VO list at the modules that need it (old bikes it was the ZFE, Kombi and DME), and then each module one by one in a specific order gets flashed with software (updated if there is any, or a new version of what it had).
I have no idea if your bike can have that alarm module - one way is to find a bike that is the spec you want to replicate - and take a photo of the VIN - then go here
https://bimmer.work/ (or one like it) and check its VO - it will list on another tab what options it has
just to confuse the
DWA option was 0603 Alarm system
XDWA option says 0603 SA Anti-Theft Alarm System
here it only listed USA region bikes - and seems to have another version of an alarm ?
