Is there a location inside the car designed for storing the tow hook? Mine is just rattling around in the back.

 

If you have an unexplained open space under the floor of the trunk area, right side, one of these two parts will sit within and can hold your tow hook.

71106857371 - Tray for vehicle jack
71106877569 - Storage tray, mobility system

Google 'em up, either has a spot for the two hook. I picked up the first one for my F56, as well as the jack shown in the diagram. Easy enough to find these on eBay (whether just the tray or the tray + some of the other parts you'll see in the diagrams).

 

Thanks for the reply
