How do you get the spare wheel off a citroen relay van?

Hi just had air escaping from between rim and tyre so needed to change wheel and No Manual! (Yea I know simple for those that have done before) So here goes: wheel is underneath rear of van - on left rear of wheel retaining bracket you will see a verticle tube which your jack will go into and just take the weight to lower! Next open the rear van doors and on the black plastic inside part of the bumper trim you will see 2 x small squares of plastic with cut-out slits either side (put screw driver in both to easily lift off) = 2 x silver bolts = undo until bracket will swing clear of retaining hooks (dont fully remove). Now lower jack so wheel can slide out! PS As typical you will find small indents in the lower sill side panels indicating where the holes are to put the jack into, well done Citroen it was fairly straight forward. HOWEVER the ratchet spanner broke within 1 minute and had I not had a huge adjustable in my van I would have been stumpted at the side of the road!
