Hi, done this myself recently. Unfortunately i did the whole dash out thing. you don't have to. theres a 13mm nut and bolt that goes through the pedal box. with your head in footwell and lying on your back with feet up near seat headrest (seat reclined). don't worry about the return spring it goes back together quite easily. once the pedal drops free, release clip and pull out. replace plastic retainer and clip ( 8 pounds from citoen dealer, you probably won't need a cable) to the pedal,feed cable into retainer making sure it's fully home and locate clip. make sure the clip is correct position or cable may pull straight out when you first try it. Re-assemble. should be fairly easy, it took me three days the other way, i reckon 1-2 hours this way. good luck.
