Self Leveling Rear Suspension? - Need Help

[F150 Duke]

All,

The self leveling rears suspension is an important feature for me in the X5. Reading on the forum says it’s a part of the V8, third row seat or adaptive drive orders. Minnetonka BMW hasn’t been able to answer the question and then Motorwerks BMW said it was a part of the third row seat option ($1,700) or the adaptive drive option ($3,500)…ouch on the adaptive drive.

Can anyone confirm/deny this or help me find the true answer? I really don’t want to pay for these features if the self leveling rear suspension is standard on the diesel. The adaptive drive is way too expensive and the third row seat is a useless waste of space when I could have that spot as storage.

Thanks!
