Hello –
If you need to get back with me, there are different models Audi A6s. Please let me know from the below Pic.
Next, check fuse number 6.

All theses systems run through your Central Locking Control Module located under the driver’s seat and carpet.
You might also check to see if a plug was disconnected under the seat.
When you check the fuse, please make sure you use an ohm meter or replace with a known new fuse. Even a blown fuse can look good.
Let me know what you find.
Thanks for the donation
