I’ve just found this on the Enyaq forum, is this maybe the issue re ambient lighting?
The ambient lights will come on when it gets dark. Usually alongside the auto head lights. The Crystal grill comes on too. You can set it when approaching to turn the lights on if its dark, the grill does its little animation and the interior lights glow red if locked and green if unlocked when you approach/lock/unlock the car. They are not very bright so very hard to see in the day time. The ambient lights are not standard on the loft interior in all countires, it is in the UK though.
