Heater matrix removal P38 diesel

I only get clear water dripping in when I use the A/C on seriously cold. It mostly drips through the OBD socket.

Call me thick, but I haven't started to look for the leak. Where should I start?

I mean, I "know" it's the A/C drains, but imagine I'm thick (doesn't take much)....where would they be and how simple is it to replace them?

Remove the side panels from the centre consul. Look under the heater unit and you should see two convoluted rubber pipes one either side. They should be located on the drain tubes at bottom of heater unit and then are grommeted out through floor. If they are split or damaged change them. Part number is AWR2722.

I don't think the aircon drains will leak on the ODB socket, would they? I'd be much more suspect of water ingress round the pollen filters or possibly the screws under the windscreen trim if it is dripping on the ODB socket.

I would imagine that if the drains are blocked from the evaporator part of the box, then moisture could run back out the air intake, as no doubt the foam holding all the ducting in is pretty perished by now - so if the ducting is loose, then it will provide a path for water to get out... from memory, then air inlet to the A/C + Heater box from the blower motor on the passenger side is somewhere above the OBD socket...
