I have the same question.

I have bought the BMW X6 with sport seats. I have installed the comfort seats.
However I cannot control them. The electricity does not work.

I could only move the seats via OBD Port access using the BMW software INPvA.

The guy who did it told me that I will need to rewire the can bus. As the sport seat also had no memory seats and no seat heating lots of pins and cable are missing.

I really thought thiw would have been an easy retrofit.

However it is not.
