Immobilizer Generation 3

VCRPIM030

The following procedures detail how to match immobilizer components to any VW, Audi, Seat, Skoda etc. model that uses Immobilizer Generation 3. The instructions vary depening on the exact model/equipment. Make sure to use the proper address/control module, depending on which control module is the immobilizer master in your specific vehicle. For details, check the individual vehicle pages. The immobilizer master can either be integrated into the Control Module for Access/Start Authorization (#05), the Instrument Cluster (#17) or the Immobilizer Control Module (#25).

Key Matching (New)

Prerequisites

Immobilizer PIN/SKC for Vehicle is known/valid
All keys are either new (unlocked) or were adapted to this vehicle (immobilizer identity) before
You can match up to 8 keys
While adapting each key, make sure to place the other keys away from the ignition lock (reader coil). The passenger seat is an adequate place.
Battery Voltage > 12.5 V

Step	Function/Action	Instructions/Input	Comments
1	Control Module [05 - Acc/Start Auth.] OR [17 - Instruments] OR [25 - Immobilizer]		Select proper Address.¹
2	Function [Meas. Blocks - 08]	#05/25: MVB 001 #17: MVB 022	Field 3 must be 1!²
3	Function [Meas. Blocks - 08]	#05/25: MVB 003 #17: MVB 024	Ensure all Lock Times (Field 1-3) are 0.³
4	Function [Login - 11]	Enter 4-digit PIN/SKC with leading zero. Press [Do it!]	For example, if your PIN is 1234, enter 01234.
5	Function [Adaptation - 10]	#05/25: Channel Number 01 #17: Channel Number 21 Press [Read]	The *Stored Value* is the number of keys currently matched.
6	New Value	Enter a NEW VALUE corresponding to the total number of keys to be matched, including any/all existing keys. Press [Save]	The Immobilizer Warning Light will light up for ~2 seconds, wait until it goes out, indicating that the key has been matched.
7	[Done, Go Back] [Close/Back - 06]
8	Ignition OFF (Remove Key)
9	Insert NEXT Key WAIT	Repeat Step 9 & 10 until all keys are matched.	The Immobilizer Warning Light will light up for ~2 seconds, wait until it goes out, indicating that the key has been matched.
10	Ignition OFF (Remove Key)	Repeat Step 9 & 10 until all keys are matched.

Finalization

The above steps after saving the adaptation, should not exceed 60 seconds withing matching 2 of the keys and having one key in the ignition should not exceed 30 seconds!

Key Matching (Used)

Keys are locked during their initial/first learning process and cannot be learned/matched to a different immobilizer system via factory procedures. Therefor, existing keys from a specific vehicle and immobilizer identity can be re-learned/matched to that same vehicle/identity at any time, while used keys from different vehicles or old identities cannot be learned/matched!

Engine Control Unit (ECU) Swapping (New)

Engine Control Unit (ECU) Swapping (Used)

Immobilizer Master Swapping

Injection Pump (VP44) Swapping

After installing a new or used Injection Pump (VP44) in certain 2.5l V6 TDI engines, the replacement pump needs to be matched to the vehicles immobilizer system.

Prerequisites

Immobilizer PIN/SKC for Vehicle is known/valid
The NEW Injection Pump has been installed
Battery Voltage > 12.5 V

Step	Function/Action	Instructions/Input	Comments
1	Control Module [01 - Engine]
2	Function [Login - 11]	Enter 4-digit PIN/SKC with leading zero. Press [Do it!]	For example, if your PIN is 1234, enter 01234.
3	Function [Adaptation - 10]	Channel Number 050 Press [Read]
4	New Value	Enter 4-digit PIN/SKC with leading zero. Press [Save]	For example, if your PIN is 1234, enter 01234.
5	[Done, Go Back] [Close/Back - 06]
6	Ignition OFF (Remove Key)	Wait min. 60 seconds for the control module after-run to complete.

Finalization

Wait min. 60 seconds for the control module after-run to complete before you proceed.
Start the engine to verify the learning/matching process was successful.

Measuring Value Blocks (MVB)

A more detailed description will be displayed via the tool tips for each measuring value in VCDS while reading the live data.

Block	Field 1	Field 2	Field 3	Field 4
001/022	Engine Start permitted 0 = No 1= Yes	Engine (ECU) responds 0 = No 1 = Yes	Key Status 0 = Key NOT OK 1 = Key OK	Number of (adapted) Keys max. 4/8 Keys
002/023	Variable Code authorized 0 = No 1 = Yes	Key Status (Transponder) 0 = New/Not Locked 1 = Locked	Fixed Code authorized 0 = No 1 = Yes	Immobilizer (Adaptation) Status 4 = Customer Service: NEW 6 = Customer Service: Adapted (Normal)
003/024	Lock Time,Immobilizer (Minutes)	Lock Time Engine (ECU) (Minutes)	Lock Time Transponder (Minutes)	Immobilizer (LED) Status 0 = No Malfunction

Models equipped with Keyless Access and Start System (KESSY) and/or Electronic Steering Column Lock (ESCL) as well as multiple Engine Control Modules (ECM) will show additional relevant data in other MVB's.

Retreiving VIN & IMMO-ID

In order to retreive the PIN/SKC via official channels, the Immobilizer ID is required for each component for which a PIN/SKC needs to be requested. Due to slightly varying implementations, either step 2 or step 3 of the following table will work (choose whichever variant works in your specific case).

Step	Function/Action	Instructions/Input	Comments
1	Control Module [01 - Engine]
2	Function [Main Controller Menu]		"Extra" Field contains the 17-digit string (VIN) and 14-digit string (Immo-ID)
3	Function [Meas. Blocks - 08]	MVB 081	MVB contains the 17-digit string (VIN) and 14-digit string (Immo-ID)

Video Tutorial

Select applicable control module address for immobilizer master the vehicle you are working on. ↩
If the value is not 1, the current key cannot be adapted to this vehicle/immobilizer identity. ↩
Each field represents a lock time in minutes. If the lock times are NOT 0, do NOT switch off the ignition! Allow the car to sit for AT LEAST the number of minutes that were indicated by the fields 1-3. ↩
