Minor update/correction.
On my girlfriends 1.4 chill, the horn/airbag bit isn't held on by the 2 clips, but by 3 T30 torx bolts.
1 left 1 right 1 bottom centre of the wheel round the back.
they don't unscrew all the way out so it's a case of trial and error as to whether their undone enough to take the unit out.
There;s a yellow 2 pin connector in the centre and a black wire to the side that need to be unplugged, gentle tugging soon gets them off (ooo matron, etc etc!)
Thanks for this
guide, currently stripping her interior out to sort some leaks and this has been a godsend on those moments when I just can't figure out how that bits held in place
