I sort of found the problem with this was. The PP2000 lead/box was at fault. I have no idea why it wouldn't read just the Airbag diagnostic line as the lead had all wires connected in the right place and used to read all ecu's fine. I now have a new PP2000 lead and setup and the airbag ecu reads fine. Ruan has a point about the connectors under the seat but no matter how many times they were disconnected and reconnected the fault wouldn't clear.
The car I was trying to diagnose had phase 1 seats put in it which will create a fault as the side airbags that were originally installed are no longer there. I tried Cully's airbag resistor trick [self built ones] and that didn't clear the 'permenant' fault. Luckily I had an identical part number airbag ECU from another 306 built within a few weeks of the car in question that wasn't factory fitted with side airbags. I then used PP2000 to clear the faults and all is now well.
The airbag resistor trick is a really good idea, but it could be worth looking out for an identical part number airbag ecu from a car that was never fitted with side airbags if your putting phase 1 seats in. Hope that helps someone.
