I am no expert in lights and it's been a while since I had A8.
Most if not all in UK have HID lights for dipped beam (or bixenon) in the projector housing which is D2S. The reflector housing is for full beam H7 and cornering light which yours does not seem to have is H8. If it's all halogen without HID then I think dipped beam would also be H7 but I don't recall seeing any in life with all halogen only in UK.
I have a pair of D2S Philips X-tremeVision gen2 that I bought for my A8 but never used so happy to sell on at discounted price
This is a link on Amazon where I got them
