Steering wheel retaining nut is 22mm. Loosening the wheel won't help getting the column unlocked. Removing it will, because you're going to have to do what Father Figure said and unbolt the column to access the tumbler and column lock mechanism. To do that you have to remove the wheel, the turn, wiper and cruise control switches and the security screws. I've been through this now with an E24, an E30 and an E36. All are differently arranged, but all have those blasted security screws to contend with. A Dremel with a cutoff wheel works great for putting screwdriver slots in the head of those screws. Fortunately they won't be very tight.
