Battery reconnected and a battery charger put on to maintain its voltage for coding. With the seats back in the car the replacement module was fitted. Today we first checked the resistance on both pre tensioners, they were both in spec, wiring connections under the seats inspected and looked fine. Next step was to source a correct module from one of the forum breakers who came up trumps with a known good module. A bit of research on Real oem deduced that the binned module and both replacements were in fact the wrong part numbers for the car. It would appear the module was from a crashed car which locks up the module and sets crash data in the internal eeprom preventing the clearance of codes.

I became involved and put diagnostics on the car which revealed codes for both belt pretensioners, they wouildn't clear and a further code F0 Internal error showed up. That didn't solve the problem so he got another used module, Fitted that and still didn't solve it. It was a salvaged car with little past history when the airbag light showed up it was due to him switching on the ignition with a seat out, being new to BMW's he binned the module and sought out a used module with the same part number of the binned one. Drove mine today to work on a mates Z3 with a duff airbag module which had put the airbag light on.
