"Recall"-Drivers air bag

[Wolfie1]

I got my letter the other day too

 

[Haven't a clue!]

Booked in, follow-up recall letter quotes "while your car is with us, we will take the opportunity to ensure that any outstanding technical upgrades are completed."
Any advice as to what "technical upgrades" they will look to update (I presume S/w) and how I can check, as moved to Indy servicing in 2015 so may be a few!
Thanks

Got my letter last December, had work done 3 weeks ago, to do with airbag connections/ fuses? Took it in at 2pm all done by 3pm while you wait eating their biscuits with tea or coffee.
