In the Facebook group called Audi Q4 e-tron Owners UK a number of people have confirmed that they have no 360 cameras and have the 360 display either on its own as the park assist option or as part of the rather pricey tech pack. One person has even reported that the side cameras are on the car, but front camera is missing. Feels like a parts issue. A big one.
Make the dealer aware if this is the case, you will have no other option but to cancel now or upon delivery.
