21. Understanding Immobilizer Systems with VCDS

Immobilizer systems are designed to prevent vehicle theft by requiring a unique code from the key’s transponder to match the vehicle’s immobilizer module before the engine can start. VCDS can be used to diagnose and adapt immobilizer systems.

21.1. Identifying Immobilizer Types

VCDS can identify different immobilizer generations. Accessing the 17-Instruments module (or 25-Immobilizer on some vehicles) and checking the “Extra” field reveals the immobilizer type. For example:

• Immo-2 (or Immo-1): “Immo-ID VWZ7Z0W0648696”
• Immo-3: “WVZKB58001H231169 VWZ7Z0W0648696” (The first 17-digit string is the VIN, the second 14-digit string is the Immo-ID).

21.2. Reading Immobilizer Status with VCDS

VCDS can read various immobilizer status parameters. Common measuring blocks include:

Measuring Block	Parameter	Description
022	Engine Start Permitted	1 = Yes (car can be driven), 0 = No (key not matched or module incorrectly adapted/malfunctioning)
	ECU Responding	1 = Yes (communications with ECU OK), 0 = No (cannot match Immo to ECU)
	Key Condition OK	1 = Yes (legitimate transponder code read), 0 = No (cannot match this key)
	Number of Adapted Keys	Maximum of 8 Keys
023	Variable Code Matched	1 = Yes, 0 = No (variable code not matched)
	Transponder Status	1 = Yes (Transponder locked), 0 = No (Transponder not locked)
	Fixed Code Authorized	1 = Yes, 0 = No (fixed transponder code of key is not authorized)
	Immobilizer Status	4 = New/replacement part, 5 = Customer service locked, 6 = Immobilizer adapted, 7 = Key adaptation in progress
024	Cluster Lock Time	0 to 255 minutes (time before another Login attempt)
	ECU Lock Time	0 to 255 minutes (time before another ECU match attempt)
	Transponder Lock Time	0 to 10 minutes (time before another transponder recognition)

21.3. Understanding Lock Times

Lock times indicate how long to wait before attempting another login or adaptation. These times only count down while the ignition is ON. Connecting a battery charger is recommended if long lock times are accumulated.

22. Common VCDS Coding Mistakes and How to Avoid Them

• Failing to Back Up Original Coding: Always back up the original coding before making changes.
• Incorrect Parameter Values: Double-check all parameter values before applying changes.
