I'm wondering if the sat nav needs an update? And wondering if that would cure the issue. Might be worth seeing if it does it again the next time you do that journey.

Ironically I'm in a similar boat to you atm. Needing the same on my a6 c5 2.5tdi abd looking up to £450 at a trusted independent. The pic shows when it was last do e 8 years ago.
Glad you got sorted 🙂 I would bday £119 isn't too bad! I've got to have the cambelt and water pump changed on my a6 at a cost of £450! But let's face it, the older the Audi the more if a labour of love it becomes 😉
I think the delay will be down to Audi shutting their production plants for a while due to covid. I see your logic about swapping to an sq7 but it might come quicker than you think if there's less q8 orders then they might be done quicker if you see what I mean.
If it's been to Audi then I would be taking it to another Audi garage for a second opinion. Definitely want this issue sorted whilst it's under warranty.
Welcome to the forum Sun, you'll find the members on here are a friendly and helpful bunch 🙂
With any retro fitting my advice would be to get a professional company. Not sure about the DRL but again an auto electrician or retrofitter can advise.
I'm sure you need more than just the head unit I'm surprised Audi didn't say what else it needed or why it wasn't working. I'd be taking it back to Audi for them to sort this.
Will be worth it. Try and get a remap done by a company who will dyno it too. Obviously you'll get bhp and torque increases but sometimes you get an mpg increase too
