Thx for that...what I know so far...
1) Make sure front wheels are straight
2) Disconnect -ve of battery LEAVE BOOT OPEN!
3) Remove 2 screws from back of steering wheel (Torx)
4) Pull steering wheel centre out & up
5) Squeeze electrical connector and pull out of steering column - be careful lead is still attached to steering wheel. Lift airbag/steering wheel up and rest on the top of the steering wheels 'T'.
6) Using an M12 Splined bit undo the steering wheel centre bolt
7) Remove wheel placing flat with airbag on top
8) Remove 2 screws from under steering column (small pozi)
9) Remove 1 screw from side of wheel clamp (underneath - pain to find)
10) Pull column upper coal up and admire the switch gear
11) Remove lower cowling - NO IDEA HOW, THATS AS FAR AS I GOT...
<<12) Fit new stem>>
<<13) Fit wiring from steering column to under footwell>>
When re-fitting turn the ignition on BEFORE re-connecting the battery terminal, I think this stops fault codes appearing re-the airbag. Also, after doing this my central locking remotes stopped working. But started working again if I opened the doors mechanically then started the ignition!.
I would say to do it you are correct - in general you need a small loom going from the column to under the cars floor where there SHOULD be a connector.
I would LOVE to know how that lower cowling comes off...
Now contemplating giving the car, stalk and cash to AmD...
