Another issue to report. ::)
All seems to work well, apart from the fuel consumption figures. I have cleared the figures twice, but they seem to keep reverting to 7.1mpg, on both instant and overall consumption. Drove for 10 miles today and they both stayed there.
Am I doing something wrong ? Is it broken ? Does it need a chat with Tech 2 ?  :-\

Possibly a Tech 2 chat would be in order, I did have something similar quiet a few years back, MPG stuck on 7 and Range going from something to 0 then F then back to range, in my case it was because it came from an Auto Saloon to a Manual Estate.

I wonder if it came from a manual car ? Could be confusing it. :-\
I want to find out if its a serious / incurable fault, as it will be going back if it is.

It reads as though the NCDC is lacking a speed pulse :-\

On the MID 7mpg seems to be the absolute minimum it will go down to. I wonder if the CID behaves the same. :-\

Does the NCDC/CID have a mileage trip like the MID? If it does you could check that the CID is getting a pulse.

Yes it has a mileage trip and that seems to be the only thing that is working accurately at the moment.

A question for someone with access to the wiring diagrammes - does the NCDC have a saparate speed pulse to the
CID?

Both fed from the abs ecu, BlRt/BuRd (depending on what language your wiring diagrams are in) ;)

Will check pin outs when I regain consciousness/get up*

*not a morning person, so delete as applicable  :D

That would be much appreciated Doctor. I'm at a loss at the moment, and while not wanting to try and remove the damn thing and send it back, I think I will have to do that if this cant be fixed.

All pin outs are identical GID/CID... :y

BUT 2001 on has a connection between Pin5 on the screen connector (the smaller, shielded cable)and Pin19 on the head unit... using the shielding as the current track...

Pre'01 it runs from Pin23 on the main GID/CID plug to Pin19...

You have connected the second cable?

Car is 02, CID unit 03. Both plugs pluged in, but I'm going to check they are both seated properly as soon as I get the chance.
Thanks DG.  :y

While swmbo was in Sainsburys today, I sat in the car park bored, so the screwdriver came out. Took the plugs out of the back of the CID (broke the locating clasp on the smaller plug in the process  :-[ :'() and reseated them. After this the overall consumption was working, although was reading higher than I expected, but the instant consumption stayed on 7.1mpg when moving, and 9.6 gall / hour at standstill.
On the way home they reverted to 7.1mpg, although sometimes when off the throttle downhill, instant went to 999.99mpg.
Looking like a connectivity problem ,but I'm not too confident of solving it.

Could be a bit of tension on the looms :-\ are the plug looms slack, ie can you pul them one end to other without snagging?

Not much slack in the loom to the small plug. I would guess its ok with the binnacle in the correct position, but not much to play with when trying to move the binnacle out of position to remove the plug.  :-\
This plug has never been used before as it was taped up and hidden, so any problem with it wouldn't have been known. Although it would also, presumably be a fault present since the car was new.

Was thinking it may have been strained...

Cars fitted from new are tight for top access/cluster removal, might be that the cable was kinked when it was first taped up :-\

Only way to rule it out is to either try both headunit and display in another car, or try to get hold of another cable :-\
