Oh-yey managed to get it working
Called Homelink and had a chat with them, they advised new batteries for the remote and then to press and hold for about 7 seconds the remote and to do it several times.
Managed to get the car to say it had accepted the code but it would not work - did this 3 times and nothing so was getting frustrated but then on the 4th attempt I held the remote very close to the Audi rings on the front grill and hey presto it works
