C4 Picasso Diag socket

Anyone know where it is?

Simon (Mandrake) is coming round tomorrow with his Lexia, so going to see what it says about the AC evaporator temperature - but need to find out where to plug it in first!

After selecting the model of car, a picture appears reminding you to plug the connecting lead into the car, down near the validate tick box there's another icon you can click on which gives the diagnostic socket location.

If I remember right its in the passangers side lower glovebox behind a little cover.

You're right Wheeler - found it earlier on, quick Google suggested the glove box and there it is.

Have you ever changed an evaporator temperature sensor on one of these?

Simon plugged his Diag box in this afternoon - it shows FIFTEEN ECUs fitted - and this is only a mid spec VTR+ without many of the twiddles of later / higher spec cars There's even one for the windscreen wipers!

Only one fault logged relating to glow plugs, but it starts OK, so just ignore that.

The evap temp sensor appears to be doing what it should and the temp dropped to just above freezing with the AC on and modulated around there, so it seems to be working. No idea then why it freezes up - will get it regassed and see what happens. Static pressure in the system was showing as 6 bar no idea if this is right or not!

It gave an exact figure for the Eolys remaining of 1154 ml of something - seems about right as it has done 56k now, and refill is supposed to be at 75k. DPF was showing 0 mbar delta P at idle going up to about 20 at 3k rpm - anyone know if this sounds about right?
