Just in case anyone else gets stuck in the same situation as myself I thought I would share this gem of knowledge...

A couple of months ago me rear screen wiper motor decided to have a bad day and set itself on fire (quite a common problem it seems)! I managed to source a new motor, connector blocks and trim etc. but I was stuck with 4 dangling wires and no perceivable way of knowing which wire went where (the connector was completed disintegrated in the fire).

After a lot of pleading with the my local Audi garage over a couple of occasions (apparently it's against their policies to give out such information) I finally got them to give me a print out of the connections.

Armed with this gem of knowledge - Tada - I now have a working wiper again hurrah
