D Had me going for a min!
shollis, it was the
1J0 971 425 stalk and loom from Vagparts. Either that or the 8LO one will work though. They cost just over £60.
I followed the guide over on this website...

The installation on the A3 differs a little bit from the Golf in that the airbag is secured by two torx bolts.
The hardest bit of the install was trying to get the black/blue wire out of the dashboard fusebox without breaking it, and access to the engine control loom is awkward!
My loom also didn't arrive with any labels telling me which wire went into which plug on the engine control loom, but fortunately I found a wiring diagram on elsawin.
It wasn't a 5 minute job, and took me about 4 hours in total, but I was taking my time. If I did another one, it would probably be a couple of hours.
I didn't take any pics of the install, as I think the website above covers most things.
I'm happy to help out anybody who fancies a go though, or needs it activating via VAGCOM if they're in the Leics/Lincs/Beds/Cambs/Notts area.
