The engine oil drain plug on the Citroen C3 1.4HDi is a 21mm hexagonal bolt (with a copper seating washer) located vertically in the oil reservoir (sump) at the bottom of the engine approximately in line with the drivers seat (RHD). Not to be confused with the horizontally located, allan slotted plug located at the rear of the transmission housing. To access the oil drain plug - (safety first - engine off, handbrake on, out of gear, wheels chocked etc) Remove the eight slotted keepers that secure the under engine splash guard by turning them through 90 degrees and pulling downwards. Some may be awkward - persevere! Gently push or (pull) the guard so that the locating tabs at either end come away from the vehicle - put the guard to one side. The hex head of the oil drain plug will be in view just proud of (mild steel and possibly black painted) engine oil reservoir. It unscrews counter clockwise. Technically, on replacement a new copper seating washer should be used. Take care not to over tighten the plug. Refitting the splash guard is a reversal of removal though I find locating the rear tabs and the two rear most keepers first makes things easier.
I found the above possible without jacking up or ramping the vehicle and I'm not small.
