Recently bought C3 1.4 HDi 16v SX. Great car, but found 1 BIG problem that nobody has found a solution to at Citroen Headquaters. How do you look the car should the central locking remote button fail? According to the manual the key should lock all doors, but on mine it only operates the drivers door!!! Tried at least 6 more in garage & all the same. So far I have been shown the emergency switch in passenger doors & how to unlock the boot from the inside with your portable screwdrive!!. However no solution as yet as to how to lock the boot. A Technical person at HQ suggested to my dealer that you lower the window, get out the car, lean back thru the window, press central locking button & close window!!!!! Guess what - this doesn't work. Any other solutions out there in C3 fan land??!!
