I have a 2007 A3 - although its a bit of a faff it just stays in - never had to remove any parts under the wing

As cliffcoggin says. I had exact same problem plus airbag light. Sorted by an auto electrician but could be a diy job.

I had this problem in 2007 A3 and it was a broken wire in offside front door loom. Auto electician sorted it in 30 minutes. Good luck.
