(KezoI’m sure it’s to do with the fact it’s go an engine). Has nothing to do with that, our Golf GTE does have remote heating/air conditioning (and an engine).
@Rene I think your missing my point on “engine”
Your Golf GTE has a resitive electric heater that heat’s the cabin, either from the battery or it’s plugged in charging. It will not start the engine (even if the battery runs down) to preheat the vehicle, unless you start the engine and take the key back in side.
The battery in your GTE is 13Kw, so is capable of running an electric heater in a similar an EV does without a heatpump. The QQ battery is not big enough to preheat without it rnning down or “starting” the engine.
It can be done in other countries but not here in the UK, as it’s not legal due to the security implications of having your car running, insurance etc.
