Its really pretty straightforward.
Remove the fuse for the horn (fuse box under the bonnet) and take your time.
Pop off the airbag (there are 3 spring release clips at the back of the wheel) and once off, just unplug it and leave it to one side. Don't worry, it doesn't cause any dashboard errors once its re-connected.
The silver/red plastic trim is only clipped on but takes some gentle persuasion to prise off. Start at one corner, tug gently with your fingers (around the haptic buttons on one side) and once you have that side freed, the rest is easier.
Once the trim is off, you'll see the Torx screws you will need to undo to remove the existing paddles. You also need to unplug them. The new paddles are a direct swap, same torx screw, same plugs.
Put everything back in reverse order!
It's well worthwhile doing, makes the wheel look so much better and the paddles are really nice in the hand to use.
