First remove the headlight switch - switch on the sidelights, then slip a small screwdriver into the recess underneath the piece that turns. There's a small tab in there that will allow you to pull the knob off (oo-err). Once that's off you will see two tabs that need to be squeezed together, allowing you to remove the main body of the switch. Now depress the tab on the wiring connector to unclip it from the surround.
Remove the screw that's in the top of the recess for the switch.
Now remove the headlight leveller control switch and the blanking plate below it, then unclip the wiring connector as before.
Remove another screw from the hole.
Remove the surround from the cigarette lighter and remove the screws that you can now see bihind it.
Remove the two switches for the heated seats (or the blanking plates) and remove another screw.
Remove the screw that is located in front of the trip comp (at the top, screws in vertically)
Remove the column shroud.
Remove the two screws from above and in front of the clocks.
Remove the two screws that are situated either side of the column - they have tiny little caps on them wich like to ping off so take care not to lose them.
You should now be able to get the surround from around the clocks, which will give you room to get to the back of the trip computer - gently push it out from behind and unplug it.
The clocks are secured with 3 screws - one at either end and one midway along the top edge - once you remove these you will be able to pull them forward to unlip the wiring connectors (x3) from the back.
I think thats about it but if I missed anything someone will shout!
