What voltage?
It would be interesting to know what other people see voltage-wise on the climate control display. Assuming 14.4V when the engine/alternator is running (ideal conditions), I would expect to see perhaps 13.8V, allowing for a sniff of voltage drop due to the battery location. Whenever I've measured the voltage connected directly to the battery terminals in the boot, it's approximately 0.3V lower when register 36 is selected, as per my previous post on how to obtain the voltage display on the climate controls.
