• Citroen C5 Dragging/Rubbing Caliper

    I found some old notes on this on my wiki, and figured someone might find them helpful

    There is a known issue with the Citroen C5, where the rear calipers may end up rubbing against the inside of the wheel (rear caliper corrosion syndrom).

    Basically the issue is one of water ingress. Corrosion develops between the mating faces where the caliper is mounted to the suspension leg, and the caliper is slowly pushed out at an angle, ultimately causing it to rub against the wheel.

    It's identifiable by metal being worn away from the caliper and/or the inside of the wheel.

  • Citroen C5: BSI Reset

    The Body control unit (BSI) on Citroens (and Peugeots) sometimes goes batshit-insane and switches things off for no other apparent reason than it felt like it.

    A reset is usually enough to resolve, but the steps need to be followed almost exactly, and the car should be thoroughly checked afterwards to make sure everything is working. 

    This documentation details how to perform the reset
