Hello
Check the relays located behide the cover above the pedals.
I think there is the relay that you are looking for.

Hi

If this Audi is the one with the big fuse box in the engine bay than it has a bolt in the center undo that bolt and see if you can get the communication also check if its not have any water in the fuse box.

Hope this helps.

See the picture with red mark that's where the bolt is located
