my n/s/r door wouldnt open with key fob or keys on my c5 hdi vtr 54 plate. disconnected battery,no good,took door panel off and looked ok ,could feel motor clicking when pressing remote,so got a price from citroen garage 195 pounds.started saving up then 3 weeks later it started working on its own. about 5 weeks later o/s/r door did exactly same thing then 1 week later n/s/r did it again so i had no back doors working and looking at a 400 pound bill.someone told me the solenoids are prone to sticking so i took door panel off and with a nylon hammer gave about 4 taps on the motor/solenoid then locked the doors with key fob then opened them again with key fob then using the operating arm that connects the opening handle to the motor pulled it and the door opened.once the door is open you can remove the three bolts that hold the motor in place and give the motor a good spraying of wd40.i did exactly the same thing for the other door and it worked same.they have been fine now for about a month.the garage told me they have to smash them out to put new locks in thats why it costs 400 pounds, it cost me half a can of wd40 and about a hour an half of my time, hope it works for you.the money id started saving to pay the garage was wisely spent in my local pub.
