Maybe you fella's have seen this before but it certainly rang a few bells with me. http://www.mez.co.uk/haynes.html

Nice one

I always liked the Haynes ones that say something like: Remove front wings and bonnet, jack up front of car and put on axle stands, remove front windscreen glass, unclip all wiring from engine, removed front road wheels and extract split pins and nuts from front outer drive shafts, disconnect fuel line, undo headlamp adjustment screw, disconnect speedometer cable. You now need to go and purchase citroen special tool xyz2300042.
