Got the smudge yesterday :)
Thought I'd detail the steps while it is still fresh in my mind.
Grab bezel by the ribs in between the displays and pull straight out to release 4 clips. Disconnect turn signal indicator wire harness.
Remove 4 screws to remove display module. Carefully manuever display module out of recess. If all you wanted was to replace a warning indicator light, this is as far as you would need to go.
Disconnect 2 more wire harnesses from rear to completely remove display module. To access backside of lens, remove 3 more screws in front and release 4 snaps on top and 2 on bottom to fold apart. The front and back of module is now only connected by flex circuit.
Total time was 20 minutes max to disassemble, clean and reassemble (only 15 if you don't drop a screw into steering column). The engineers did a great job making this modular, connectors can't be connected wrong, easily worth the effort. Told my wife I got the smudge which she replied "what smudge?"
