We have added new software for key learning for VAG-group cars with body control modules BCM2. BCM2 modules are installed in the following cars: AUDI A4, A5, Q5, A6, A7, A8, Q7, Volkswagen Touareg. 
The new software allows to adapt a new key or a dealer key to car via OBD-connector if you have a working key or immobilizer data for the car. It is also possible to adapt the key by dismounting the BCM2 module in case a working key is missing.
This software requires an adapter Special Interface and Transponder Programmer.
