i've searched on the internet and asked a few friends who recommended this site (as they are local-ish for me)
for an Audi A4 (99-01 kit) and these options came up
Specialists in HID conversion kits, HID Xenon Conversions kits & Xenon Bulbs - Xenon HID Headlight Upgrade Kits from HIDs DIRECT Ltd
i was going to buy the ULTRA KIT (£54.99), but having called them asking their opening hours
they said i need the CANBUS-PRO KIT (£59.99) and in the same search (link above)
they do a H7 kit (same box and description) for £49.99.
it seems they charge a 5er for the AUDI name at the beginning of the description and all 3 kits are canbus compatible. :S
