Recently noticed an odd things on my Q7 SE 2016:

After parking, turning the engine off and locking the car, the interior light seems to just turn itself on after a while (15-30 mins?), and remains on.

Only one interior light does this - the one embedded in the roof lining over the third row of seats.

Unlocking and locking the car again fixes the issue.

Has anyone experienced this? Looked in the MMI but can't see any setting for this. Not a huge problem but a bit worried about battery drain, especially if the light stays on overnight.
