Audi Car Diagnostics
Audi models (A3, A4, A6, Q5 and others) support the OBD2 standard. As part of the VAG group, Audi offers many software configuration features; TFSI engines commonly show timing and mixture codes.
Where is the OBD2 port?
The OBD2 port is on the driver side, under the steering wheel or in the lower panel; on some Audi models it's behind a cover.

Coding and hidden features
On Audi, hidden features like MMI virtual displays, needle sweep, mirror fold, DRL and video-in-motion can be coded. Because wrong coding carries risk, AutoMulti plans to offer it with a read–backup–write–verify flow, with approval.
