Illustration — use it to know where to look.
RHD (UK): driver's side, on the door side of the steering wheel, low down under the headlight switch. There is a small coin tray / cubby set into the dash below the light switch, next to the driver's door, and the 16-pin socket sits at the top of the recess behind its inner flap, facing down towards the footwell, so look up into it rather than straight at it. LHD (mainland Europe): mirror image, left of the steering wheel under the light switch, behind the same cover and inner flap. Same place on pre-facelift (2006-2010) and facelift (2010-2015) cars and on every trim (Edge, Zetec, Titanium, Titanium X Sport). If the socket is dead, check the passenger-compartment fuse that feeds the diagnostic socket before suspecting the car.
Two covers. Open or unclip the coin tray / trim panel under the headlight switch by hand, then open the smaller flap inside it. The socket is behind the flap at the top of the recess, pointing down. No tools needed, but the plug goes in from below, so a short right-angle OBD extension saves your wrist.
