Thanks for the help msammy. Following was my approach.

Parts: Fig 1a/b

• Sensor Mat - Part 3 on Fig 1a ,BMW part no. 65-77-6-921-952
• Control Unit - Part 4 on Fig 1a, BMW part no. 65-77-6-940-191
• Fastening Clips (get at least 15) - Part 6 on Fig 1b, BMW part no. 52-10-945-543
• Note depending upon the code that is thrown you may need only need the mat or the control unit. Using the Peake reaseacrh R5/SR5 tool, if code points you to Occupancy Senor II, you only need the control module. If it points to just Occupancy Senor you only need Sensor Mat. In my case both codes were thrown so I needed both.

Tools and Workbench: Fig 2

• 17mm socket, 1/4 drive ratchet, 3" extension
• Screwdriver with torx bits, T20, T25, T30
• 2 sets of pliers - longer is better as you'll find when it comes to dealing with the clips that hold leather in place
• 19mm socket and 3/8" drive if you want to disconnect - I ended up not doing this with no ill effects
• Blanket to protect when removing seat from vehicle
• Workbench - I found a normal height workbench to be uncomfortable to work on the seat. This saw horse set up with plywood made it much easier to get at things and move seat around for easier access to the clips that you'll learn to hate.

Seat Removal: Fig 3-9

• Slide seat back to expose nut caps/nuts securing from of seat rails to floor. Remove nut caps and nuts - Fig 3
• Slide seat forward and adjust seat forward to expose bolts securing rear of seat rails to floor. Remove bolts - Fig 4
• Slide seat forward and raise seat to highest level to expsose nut securing seat belt to floor. Remove nut - Fig 5
• Lean seat back to expose electricl connection - Fig 6
• Disconnect electrical by sliding black clasp - Fig 7 closed, Fig 8 open
• Lay blanket in door well to protect finish from damage - Fig 9
• With seat still in leaned back position, pick up the seat (to avoid dragging on carpet) and move forward while at same time turning seat to face door. From get a good hold on seat and left out of vehicle. Seat weighs about 50 lbs so get help if you need. last thing you want is to scratch anything on the rails the seat rides on have some sharp edges.
