little service flap, behind it dangles a connector to the optical cable. Here the service computer can be directly connected/merged into the fiberoptic ring that transports all data through the car.



So it's like the little flap under the oil filter (4.8) that is thought to make it possible to change it without removing larger covers.

As it's BMW you still want to or have to remove much more than such a little flap to do a proper service and inspection but the thought is nice.
