I discovered that the "tray" that holds the mobility kit has been manhandled and snapped off the bolts that secure it to the battery (see red circle in attached image)
My Z4M is being looked after to fix an oil leak from the diff so I asked the BMW dealer the cost of the replacement of this part. I was quoted something like £175... for a piece of polystyrene???
- Have you guys suffered from the same problem?
