Vehicle Information
Condition
Keys, Unable to Program
Only one key is able to be programmed to vehicle.
Technical Background
A communication conflict between the instrument cluster and VAS 5051/5052 scan tool occurs while the instrument cluster is in diagnostic mode. Normal communication is taking place allowing a message from the airbag control module to take precedence to cause a time out problem while adapting keys. Only one key is able to be programmed to the vehicle.
NOTE:
Communication conflict only occurs while in diagnostic mode and does not affect operation of airbag safety systems.
Production Solution
Start of production MY 2009
Tip:
This only applies to MY 2008 due to the change to Immobilizer with Download that was introduced in MY 2008.
