some first comments:
* Please don't use TAB indentation, only spaces, or add a ".editorconfig". Tabs have different width depending on the editor & environment. Default
indentation step for most of the code is two (2) spaces, except for some submodules (which have .editorconfig files as necessary, for example the zip
module). See https://editorconfig.org/
* ms_v_bat_12v_voltage is by default provided by the housekeeping from the OVMS ADC (supply voltage), there is currently no defined way to override this
(maybe we should introduce one?). If you set the metric, you will let the CAN data fight against the ADC measurement (see housekeeping.cpp). The advantage
of the ADC measurement is it works all the time, not only while the CAN bus is online.
* Checking ms_v_env_awake staleness to detect the switch-off will have a delay of 120 seconds, but I assume that's just a temporary solution. I bet there is
some way to read the state from CAN.
Overall, nice & clean & good remarks.
Btw, a typical CAN value scaling would be 100/256.

>>> It's quite possible the code can also partially be used on other VW vehicles (e-Golf, ID.3?), as VW tends to reuse components & protocols.
