Component Protection Manager (generation 1/2)
As part of the security strategy, some parts of the modules build in the VAG vehicles, implement the so called “component protection”.
This is a mechanism dedicated to prevent exchange of modules between different vehicles without central authorization from the VAG online database.
Such modules build in another vehicles activate the “component protection active” DTC and are with restricted functionality when build in another vehicle.
This special function allows removing this “component protection active” trouble code and allows to the module to works with its full functionality.
The component protection starts to be implemented first in the A8 2003+ and in the A6 2004+ vehicles. Component security is not implemented in all VAG vehicles.
There are actually two types of component protection – generation 1 and generation 2.
Component protection generation 1 is implemented in the A8 2003+ vehicles, while the A6/Q7/Allroad 2004+ is using component protection generation 2
for most of the modules, and only few of the modules are using component protection generation 1.
When you select generation 1 for example you will be asked to select device to adapt
as you will see on your software it s mentioned the below
07 - Control head (MMI) - Audi A6 2004-2009 - requires to read the EEPROM of the module with a programmer (24c64). You can use ZN030 -ABPROG
09 - Central electric (ILM Fahrer) - Audi A6 2004-2009 - requires to read the EEPROM of the module with a programmer (95080). You can use ZN030 - ABPROG
0E -Media Player 1 (MP3 CD Changer) - Audi A6 2004-2009 - requires to read the flash of the module with a programmer (39VF1601)
04 - ILM Front passenger (ILM Beifahrer) - Audi A6 2004-2009 - requires to read the EEPROM of the module with a programmer (95080). You can use ZN030 - ABPROG
17 - Instrument cluster - Audi A8 2003-2010 - No need to read eeprom
06 - Seat Memory Passenger - Audi A8 2003-2010 - requires to read the EEPROM of the module with a programmer (95C160). You can use ZN030 - ABPROG
36 - Memory module (Driver's seat) - Audi A8 2003-2010 - requires to read the EEPROM of the module with a programmer (95C160). You can use ZN030 - ABPROG
Currently for the most of the modules is needed first to read with a programmer the internal EEPROM (for the MP3 CD Changer the internal flash).
If it is not necessary to read the flash, the “Load dump” will be not active and the user can proceed with the next step.
You can read eeprom with help of ABPROG (ZN030) programmer.
If a module for A8 2003-2010 vehicles is selected, there is one additional step.
The customer has to connect 3 wires from the AVDI DB25 connector to the vehicles – CAN-H, CAN-L and Ground.
There is wiring diagram how to connect exactly. The user has to connect to the organge/green (CAN-H) and orange/brown (CAN-L) wires.
Additionally also the GND and +12V should be connected. The most easiest way is to disconnect some connector (e.g. the connector of the module under the driver's seat)
and to put there the two wires from the AVDI.
The ground of the AVDI can be connected to any metal part.
There is also a picture with example how to connect to these wires.
After the wires are connected the customer has to press “Read component protection data”.
for selecting Component protection - Generation 2
This special function currently works on:
•Audi A6/Q7/Allroad 2004-2008. In these cars the customer is able to adapt completely by OBDII without any restrictions the component protection for the airbag,
instrument cluster, comfort module and EZS-Kessy. For the remaining modules having a component protection (e.g. DSP, Climate Control)
the customer can adapt the component protection only if he have the Gateway EEPROM dump from the car from which the replacement module is taken
•Audi A4/A5/Q7 2007+. In these vehicles the customer is able to adapt the instrument cluster
When the special function “Component protection generation 2 ” is started the system is examined and all modules with available component protection are displayed.
From the displayed list of available modules, the customer has to select the module which he wants to adapt. Then the procedure of adapting the component protection is performed in two steps:
oReset to virgin state
oLearn module to the vehicle
Reset to virgin state
Reset to virgin state is possible to be made in three ways:
- By reading the module by OBDII (available for instrument cluster, airbag, comfort module and EZS-Kessy),
- By loading the module EEPROM dump (available for airbag and EZS-Kessy)
- By loading the gateway EEPROM dump from the car from which the module is taken (where it was originally build in)
Customer has to select from the following dialog in which way he wants to proceed.After selecting the operation way another dialog with the status of the operation is displayed:
After the operation is completed the module is in virgin state and can be adapted to any vehicle
Learn module to the vehicle
To learn the module to the vehicle it is necessary to have the Gateway EEPROM dump from the car where you install this module.
You have the option to read the Gateway EEPROM dump manually with a programmer, or to read it by OBDII. Reading by OBDII takes normally about 3-4 min,
but requires a module reflash. If the gateway is once reflashed, further operations of the EEPROM reading don't need reflash.
So the customer has the option to select whether he wants to read the EEPROM dump by OBDII, or to read it with a programmer.
If he selects to read by OBDII, then the next dialog displays the status of the operation.
Once the EEPROM data are read/loaded, the adaptation of the component protection is performed. Once this step is completed successfully, the module should be fully functional.
“Audi A8/VW Toureg/Phaeton/Bentley/Cayenne - Kessy adaptation by OBDII”
This function is dedicated to adapt “second-hand” immobilizers from one vehicle to another.
In general the earlier VW Touareg/VW Phaeton/Porsche Cayenne/Bentley continental allows adapting the immobilizer using only PIN code and adaptation on channel 50.
But A8 and later models (after 2007) require using this special function.
To adapt the immobilizer to the car you need the existing PIN and CS of the “second-hand” immobilizer.
You can extract it by reading the EEPROM dump of the second-hand module, or if you have the engine control unit from the car where you take the replacement (second-hand) module.
Starting this special function the following dialog is displayed:
