Can you show the hud? Never seen one and apparently it can't be filmed so no video review shows it. Is it really across the whole windscreen?
YETi have none of those faults
VW did replace their Software boss during the summer
The centre screen doesn't have automatic mode for it, just the maps, which isn't changing even if the light are on or ofI have automatic dark mode for the center touchscreen as well. It goes dark when the headlights come on.
Not as easy as you think. The 12V battery _is_ allowed to draw the power from the main, that's how it's recharged while the car is "on" (via a DC-DC converter, basically equivalent to an alternator/generator on a running engine). However, when the car is fully "off", the main battery is hard disconnected on the contactors (very large relays) as to make the high voltage system of the car safe. When they are disconnected, the 12V system is "on its own" - nothing draws power from the main pack, including the DC-DC system. The 12V is also needed to re-engage the contactors and enable the HV system again, which is why the car cannot be charged or used at all if the 12V runs empty.This issue would be easy to solve by allowing the 12v battery to be able to draw power from the main EV battery
As said, it does. Some evs do this also when you contact the car through the app, which solves most problems since you generally check this every other day or so, even when not driving the carThis issue would be easy to solve by allowing the 12v battery to be able to draw power from the main EV battery

Now, a clever solution to this is to keep a watch on the 12V battery state while the car is off/asleep, and re-engage the contactors and let the DC-DC recharge the 12V periodically if needed. This is what Tesla eventually implemented after having the same issue early on. I assume this functionality must be present in the VW as well, but possibly unreliable or the waiting period is too long / standby drain on 12V is too high to reliably get it recharged before it runs lower than is needed to re-engage the HV.

My thought about it, is the dc-dc converter enabled when the car is plgged it?
