Thanks for comment. I thought it would be something trivial. Local Audi said they’d need to book car in for 2 days to take a look - based on description of issue. And CG, having already taken a look, did not offer up a simple solution...
There’s no damage and the black housing on the cable where the clip fits is intact (and the cable runs smoothly). So just a clip in as you say...couldn’t find one on the internet so I guess I’ll stop by Audi before the appointment to see if they have one...
