I had a chat with Gavin today and relayed all of the comments received from the forum members and he is leaning towards fitting a CO potentiometer so I will drop the car off at Autocraft tomorrow morning for it to be there Monday morning when Gavin will remove the leads from the Lambda Probe and attach them to a gizmo that replicates a variable resistor as a substitute CO pot and analyse the CO emissions. If this works we will then wire a CO pot to the Lambda Probe leads and send it for an MOT.
I have checked the part number catalogue and have found on page numbered, (or so it seems), 17.401 what I believe to be the CO Potentiometer numbered as 3 in the diagram and 77 00 722 068, can anybody confirm this or provide the correct information, please.
Regards
Paul.

Looking at the ECU inputs the Lambda connects to the injector circuit and pin 35 and the CO pot to 35 and map sensor ..The Idle CO does more than just work at idle ,it gets data from all the other sensors .It just works at idle as you have no air temp data with the throttle plate closed .
May well be OK but I'd check AFR's on boost before giving it any big beans .
