Hi old son I cant be sure but normally they are a push fit and held in by lugs, if you look at picture one you can see two black tangs coming up parallel to the resistor pack. I would think you squeeze these together and gently pull out the pack. Have a look at this picture it may help http://www.ebay.co.uk/itm/Citroen-Berlin...1815594806
On other motors its usually one or two screws and remove but I cant see any screw holes on the citroen one.
Hope it helps hopefully someone who has done it will come along with advise.

So the resistor rack is definitely fitted in the motor housing? I can see the two tangs but I think they hold in the cable connector? When I look at my installation there is a cable that comes out of the loom just before the plug that goes into the motor. That plugs into something which could be fitted into the ducting from the motor. Could that be how the resistor pack is cooled? Thanks for your input, hopefully somebody has carried out this fix on a B9
