    perhaps its your vagcom lead thats the problem?

    I know some of them can be funny... Mine doesnt like connecting to the climate module in craigs S4 for instance.

    Yeah i thought that to begin with but neither H8CAK in southampton nor Doug@mrc could connect to it during it health check

    Which relay is it??

    perhaps a wiring fault then?

    Check the wiring diagrams and see if there is continuity between theappropriate pins on the airbag module and the diagnostic socket

    Also might want to check that the airbag module is getting power, does it have a fuse?
