Thanks for the write up.

Instead of cutting and Allen key, I bought an Allen socket from Harbor Freight and punched the key portion out. It was a perfect length.

The process is straight forward, but just a PITA trying to get the key into the plug. I ended up trying to tape the key onto the wrench, which kinda worked, but then I could not remove the wrench to readjust it. So I ended up using two fingers from each hand and stretching around the brace near near the case to put the key in.

Then I used my foot to push hard enough to overcome the torque necessary to break the plug loose.

Oh, and I did not need to reset any codes for my 2006 330XI. Been driving for 50 miles now and no problems/codes/faults.
