APC Help needed Fault Code 429B0

The APC on my 92 CS Carlsson 2.3T is showng fault code 429B0 when read with Tech2 and the car is running only base boost. The manual indicates the code corresponds to incorect version coding.
The APC version coding is apparently acheived via a link in a connector in the loom. My car appears to be correctly coded as there is no link present and I understand this to be correct for my car. The voltage levels at the main APC connector correspond to those expected when no link is present (about 6v DC). The Base boost problem has been intermittent, but seems to be perment now. The symptom described for the fault code reported is base boost only so it all seems consistent.
Any Ideas as to what the actual fault could be or how I could attempt to fix it ? Red box APCs for CS Carlssons arent that abundant or affordable so I dont want to cook one by just trying one out.
Thanks
Roger
