Hello Jamie,
I think the part your looking for is part number:
431853397
They appear to be available on the Audi tradition shop, I’ve not used it myself but I think a few others have on here with good sucess, but I seem to think the P&P maybe a little exuberant!
Try the following link:

If you find any closer to home let us know, I don’t need any right now but you never know for the future!
All the best,
Simon
