Shut-off stage for auxiliary heater (shut-off stage 5):
If this shut-off stage is activated the auxiliary heater is subject to the following restriction:

As shut-off stage 5 is only set when shut-off stages 1 and 2 have been passed, all
consumer restrictions entailed by stages 1 and 2 are also active.

Shut-off stage 6 ensures that the control units only remain "awake" briefly below a specific
battery charge level. This function is only activated in response to so-called wake-up events
(such as a door handle being turned) for the CAN/Most bus.

I hope some of you find this information useful..
Thanks :)

Furthermore, VCDS can extract history from the BEM module and additionally VCDSToolbox can be used to read the data file. You get more information with the 'C' revision module using software 550 on the D3 than the earlier modules.
