This special 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 allow to adapt the immobilizer using only PIN code and adaptation on channel 50.

But A8 and later VW models (after 2007) require to use 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 from which you have taken the replacement (second-hand) module.

When starting this special function the following dialog is displayed:

So you need to load the EZS-Kessy EEPROM dump, or to enter the PIN and CS of the second hand module manually.

ATTENTION: You should know the power class of the engine control unit before you execute this function! After pressing the read button, the customer has to enter the power class manually. If you enter the wrong power class and this is a working vehicle (i.e. ECU and Immobilizer are adapted), the car will stop working. It will start working again only if you put the correct power class in the beginning of the procedure. This is so because the Immobilizer (Kessy) will take the power class you enter.

ATTENTION: If you put the CS manually (i.e. you put 6 bytes of the CS) and there is a working key for the immobilizer (Kessy), after finishing with the reading, the Kessy will no more recognize the key. To start recognizing it again, you should put the 7th byte and press “Change”.
