Overview – Introduction
The Immobilizer is a theft-deterrent device that adds a layer of security to VWGoA vehicles that include the following brands: Audi, Bentley, Lamborghini, and VW. Certain repairs such as replacing emission parts cannot be performed without resetting the immobilizer code for the vehicle. This is done by a technician using the VAS for PC software to synchronize the immobilizer code embedded in the ignition key with other codes resident on parts such as the Transmission Control Module, Engine Control Module, and Instrument Cluster.
Before you can replace an emission part
Whenever you replace an emission-related control module, the immobilizer must be reset using the VAS for PC software. This can only be done if you meet the following requirements:
- You have enrolled into the program (see step 1 – Complete Pass Thru Enrollment Forms)
- You have received an email from VWGoA that contains a Security ID and Password to access the immobilizer application hosted in Germany
- You have received an email from VWGoA that contains a certificate file (e.g. IndepeDeale.30001.300999.pfx)
- You have installed the certificate onto your PC
- You have obtained a J 2534-1 Pass Thru device (see recommended J 2534-1 Pass Thru devices)
- You have performed the steps outlined in VAS for PC Setup
Recommended J 2534-1 Pass Thru devices
Pass thru devices are available for purchase from a recommended Manufacturer for registered workshops to perform Immobilizer functions. The Pass Thru devices that have been tested to work with VAS for PC follow:

FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : If the HV battery management control module resets while driving, the vehicle’s electric motor will not be supplied with power for the duration of the reset. In rare cases, the pulse inverter may be deactivated while driving. Each of these conditions may lead to a loss of propulsion without pre-warning and may increase the risk of a crash. Description of the Cause : Battery management control unit software: The self-diagnosis software of the HV battery management system is too sensitive in certain situations. This may lead to an unnecessary reset of the control unit. Pulse inverter: A software failure may lead to incorrect evaluation of internal measurement values. If this is detected, the pulse inverter may be deactivated.
