They DO all have it, it’s in the manual and there’s settings for it on the touchscreen. Asi understand it Enyaq has all the hardware for it but again it’s the lack of someone pushing this thru.
A recent study in the UK found that a bidirectional charger costs about £3700 it’s the lack of chargers and cost that’s holding v2g and v2g up. No ones making chargers cos no one will buy them vs a normal charger at a fraction of the cost so no car manufacturer will bother finishing it in their cars because it’s pointless as no one can use it. They are coming Google it there’s trials and announcements but nothing with a price on yet. I wouldn’t be surprised if its another 3 years before v2g is viable tbh sadly
Sadly until the charger situation changes only V2L makes sense and right now that is not supported on an Enyaq, but it could be via software update (don’t hold your breath)
