performed, it is possible to lose this pairing due to outside influence.
This TSB contains three sections, giving an overview of best practices when performing an immobilizer
adaptation:
Section 1: Immobilizer Adaptation Key Placement To Reader Coil
Section 2: Verify Adaptation Of The Audi Advanced Key Transponder
Section 3: Verify Adaptation Of The Key And Remote To Vehicle Immobilizer
