Strictly looking at these three vehicles, it would appear that either 4UB (3rd row) or 300 (spare tire) adds weight in the rear, and therefore includes 220. The two with 220 also have 330 (sports package).

Now I'm curious to know if I have 220; my X5d is a 2011 with minimal options, but I did order the sports package and spare. Unfortunately I will be separated from my X5d for a couple of months, so I am unable to look underneath.
