Hazzydays do it for a grand! http://hazzydayz.com/genuine-audi-auto-folding-mirrors-602-p.asp I think the reason it costs so much more afterwards is the factory fit is essentially an upgrade from one type of mirror that you're already paying for to another, whereas an after fit, you're buying new parts outright without being able to trade in your old parts. You might be able to flog them on though I suppose.
