I have a 2025 R12 nineT (R12S, actually) that unfortunately did not come equipped with the tire pressure monitor (TPM) option. I would therefore like to do a retrofit to add it.
As I understand things, late-model BMWs now include the TPM functionality within the XSLZ03 controller. A GS-911 autoscan shows that my bike indeed has such a controller.
It was my hope that the late-model bikes have everything needed to enable TPM except for the tire pressure sensors themselves. Alas, that seems to not be the case...
I procured the appropriate sensors (the LDL-manufactured units that can speak to the XSLZ03) and a wake-up tool to activate them. If I attempt to use GS-911 to learn the new sensors via the XSLZ03 service functions menu, it appears that a signal is being received from the sensors, but GS-911 says 'no response from the vehicle'. In speaking with my BMW dealer, I'm told the following: "the bike has to be programmed at a dealership to change the vehicle order so the bike knows it has them and reads them". Them is of course referring to the TPM sensors.
Has anyone found a workaround? Is there a workaround? I could simply take the bike in to the dealer, but I was hoping GS-911 would enable me to handle this myself. Thanks in advance for any insight.

In the following link the OP describes how to retrofit the Schrader RDC. It doesn't apply to the newer LDL units but I mention it because most dealerships would say that you can't retrofit it either with a diagnostic tool but that's typical dealer BS. Hopefully you will find a way.

Thank you for the reply.
The linked thread is informative. It seems I need an option to enable the tire pressure monitor function within the XSLZ03. The XSLZ03 controller exists and is obviously part of the vehicle configuration, but I don't see any way to configure it within GS-911. I believe the necessary functionality/hardware is present; I just have no way to enable it. Very frustrating...
I also looked at the release notes for the October update, but I'm unsure what is meant by tire pressure monitor retrofit support. If it means enabling the OEM system on bikes that did not originally come equipped with TPM then perhaps there's a glimmer of hope that, with enough patience, a similar update will become available for my bike.
