For repair or retrofit?
If you are a fairly confident DIYer the loom is very simple to make up yourself, a few repair wires and plugs from Audi, some thinwall cable, shrinkfit and some binding tape. You can add puddle lights/warning lights/ambient lighting etc. at the same time at little cost! If it's a repair you'll have most of the the component parts already. Let me know if you need any help with part numbers.
If you're retrofitting folding door mirrors you don't actually need a new loom as the mirrors plug directly into the door module itself (which you might have to change).

(10 days isn't actually bad for a back-order. I waited over three weeks for an aerial amp and only got that when I chased it with Audi CC!)
