Interesting, I have the euro switch and the dimmer works and I have no issues. Could you have bent a pin plugging it in?

Thanks for replying and confirming. I dug into the switch because it didn't make sense that BMW would use a different feeling rheostat in Euro cars than it does in the US ones. What I found was that the dimmer wheel you adjust has a gear on it with a fixed amount of rotation. That gear engages another gear on the rheostat (attached to the circuit board) which has a larger degree of fixed rotation. The switch had obviously been a part before because the two gears, which don't go all the way around, were not engaged. The rheostat on the board was turned all the way in one direction so that the teeth of the gear were facing the board and not the switch. I adjusted it to its midway position as well as the switch, put it back together and the dimmer now works perfectly.

And in better news, this also solved the battery drain warning! Even with the car off, the instrument dimmer rheostat adjusted past it's intended stop point appears to be enough of a draw to cause the warning. Never would have guess that, but alas, all is well!
