Just installed BMW advanced eye camera on my F10 few days ago. Somehow it delayed me comfort access i.e. When I touched the door know at drivers side or any of the doors, there's delay in recognition and unlocking the door like close to 30over seconds. The same goes when I want to lock the doors. When I power off the camera to isolate the issue, the door access is working fine again!! Can this be due to battery drainage below 12v? Or some radio interference?? Appreciate advise/comments to rectify this problem.
