This information was passed onto me recently, although I’m way out of warranty and don’t need derestrictions as I have the Speed version fitted now

Loving it! Info below, read the detection paragraph!:
NEWS BY ROTWILD
Our engine supplier Brose is providing a new update of its software with which, among other things, the function of the pushing aid is improved, damage to the belt is detected and consequential damage can be avoided. In addition, the update with revised algorithms increases the stability of the electronic system. A new display design can be set on the Brose Allround Display, and the options for customizing the motor support have been significantly improved.
The software update 7.4.1 has been available since April 1, 2021 and can be installed for the following Brose motors via the ROTWILD specialist dealer:
Drive S Alu, C97272-100
Drive T Alu, C91143-200
Drive S Mag, horizontal, E06855-200
Overview of changes to software version 7.4.1
Improved pushing aid: The new pushing aid no longer requires 1.5 turns of forward movement on the rear wheel, but provides full support as soon as it is actuated.
Error 29: The algorithm has been readjusted for improved system stability, so that the hard shutdown (abrupt system shutdown) in the case of error 29 is only active if an e-bike system component has a long communication breakdown. Any short-term communication interruptions no longer cause the system to shut down.
New manipulation detection: The new manipulation detection ensures that the drive detects when the spoke magnet has been attached to the crank and thus the rear wheel and crank are moving in a ratio of 1: 1 to each other. If this is the case, the drive switches off the assistance after 500 pedal turns. Error 47 becomes active and can be read out in the service tool.
Detection of a belt break: In the event of a belt break, the drive switches off immediately to prevent consequential damage to the mechanics. The error code 48 becomes active and can be read out in the service tool. If the bike is restarted, the error is deactivated again.
