Hi Ross
I'm not sure if the data within the SRS control unit has been downloaded by/for Audi as I recall reading an article a few years ago about the data being captured post accident by the manufacturer as the control units were on an exchange programme (obviously being replaced in the event of an accident deploying the airbags) and therefore they kept the old unit and provided a new programmed one.
If this is the case then they (the manufacturer - Audi) would have this data and I doubt they would be sharing it unfortunately.
