vag-com is a VW/Audi diagnostic tool.. plugs into to the OBD-II port on your car and is used to get engine fault codes from your car. when the check engine light comes on, the engine ECU records the fault code so the dealer (or you) can determine what exactly tripped the CEL.

your audi dealer has VAG-COM units, or you can buy one here.
