The Airbag light was intermittent, now on all the time, garage diagnostics showed no fault codes, thought to be airbag module, reset module, light still on, rechecked by garage diagnostics, light went off, drove one mile, stopped engine, light on again when restarted, currently looking for reliable wiring diagram. Any help appreciated. Thanks Octogen.

Welcome.
There are quite a few posts on here about the airbag light. One of the most common places to check is the green seat belt connector under the driver's seat.

Check both connectors under the drive seat. A P O has managed to break the locking clips on both connectors on mine so they work loose when the seat is adjusted.
Solution, use cable ties to keep the connectors together.

Generic diagnostic units will not read the PSA airbag controller. Needs to be the factory diagnostic system, Diagbox. If they found no codes, then they don't have Diagbox.
Could be as said, seatbelt SRS modules, the airbags themselves, the steering wheel clockspring, and finally the airbag controller. Without Citroen diagnostics you will never know unless you get lucky with a connection.
Haynes manual has good wiring diagrams.
Also as you saw from Multispacers' thread, the red and white canbus cables can be broken in certain places and splice repairs solved the problem, but you need Diagbox to know what the issue actually is (like data line open circuit etc)
