One possible cause of rough idling in an Audi A8 could be a dirty or clogged air filter. Try replacing the air filter first and see if that improves the idling.

Another potential reason for rough idling in an Audi A8 could be a faulty oxygen sensor. It's important to have this checked and replaced if necessary, as the oxygen sensor plays a crucial role in regulating the engine's air-fuel mixture.

If the rough idling persists even after replacing the air filter and checking the oxygen sensor, it could be a sign of a more serious issue with the engine. I would recommend taking your Audi A8 to a certified mechanic for a comprehensive diagnosis.
