BuDeNy,
Hopefully, this helps.
1. My vehicle is the Left Hand Drive American model.
2. I DID have to disassemble the lower half of the dash panels.
3. I found later that I did NOT have to loosen the actual steering wheel or it's column.
4. I have had my gauge cluster out and back in half a dozen times since this original posting for other modifications and I have not had to remove or loosen the steering wheel or it's column.
The cluster DOES require you to lift the top dash panel slightly to clear the upper clips/corners of the gauge cluster to tip it out and pulling the steering wheel out as far as it will go on it's adjustment also makes things easier.
I do have a bit more detailed instructions on how to remove the steering wheel than the service manual provides. For the steering wheel center bolt use a 10mm Allen wrench (Socket style).
1) Disconnect negative terminal of battery.
2) Remove the airbag.
Unbolt airbag using the T25 or T27 Torx driver.
Carefully remove electrical connector and set airbag aside in a cool dry location facing up.
3) Remove the steering wheel. Check that alignment mark on steering shaft is accurate and clear before removing wheel (clarify as necessary). Unplug horn wires, feed horn and air bag wires through relief in wheel as it is removed, and take care not to rotate clock-spring while wheel is off.
These instructions are courtesy of the paddle shift kit installation document developed by member

I hope that helps.
