Thanks for the replies.
The privacy glass, armrest and climate control were all separate options originally, but my understanding is that for the current build year, Audi have changed this so that instead of being available separately, they have been grouped together as an option pack.
I have ordered the car, but have been told by the dealer I can add on the pack if I let him know by the end of the week.
However, I think I’m pretty much decided I’m going to leave it. If I was buying the car and keeping it for x years, I’d probably do it, but for a 3 year lease I don’t think it’s worth it.
The dealer has said that I can add after market privacy glass from a local company when the car is delivered for around £200, so I may do that.
