Cayman s 2009 airbag problem

[blue dog 473]

Hi
In need of some help, had new airbags ( passenger, drivers door, steering wheel ) fitted,
all fault codes were removed except one, THORAX 800 C.
When trying to remove this fault code the airbag warning light goes out momenterally and then returns again.

Does anyone know which airbag /fault this code refers to, and has had similar problem,
and fix.

Thanks

Nigel.
