The fridge will work if its a genuine BMW towbar and the car isn't to old. I'm not sure when they changed it as my 2012 BMW 5 series had pin 10,11 and 12 missing from the 13 pin socket.
My current car is a 2018 BMW X3 and the pin 10 (ignition live) and 11 (ground return for 10) wiring is fitted as part of the towbar option from the factory. The interesting thing is that the ignition live only activates under certain conditions one of them being being a battery voltage sensed on the end of the connection. So if you connect it up to a tester it wont show an ignition live as it doesn't see a battery there for battery charging but when on my caravan it works fine.
