Hello, I have a '04' 2.0 Diesel Auto C8 which I love but it does have its quirks. Does anyone know how to switch off the child lock on the sliding rear doors. I have the owners manual which shows a switch to be operated on each door but there is no switch in the location indicated, just a blanking gromment. When the door release fitted to the pillar for rear seat passengers to use is pressed, all that happens is that you get 3 beeps. The local Citroen dealer has no idea! Thanks in advance. :(
