Bug won’t start

This TSB applies to all 1994-2010 VW vehicles equipped with an immobilizer system. An additional electronic key/transponder attached to the same key ring may cause interference problems with the immobilizer system. The message “Immobilizer active” may appear in the dash insert.

The following faults may be logged:

-          address 01: Engine Control Unit SAE code P0513 – incorrect immobilizer key.

-          address 25: Immobilizer SAE code 1177 – key implausible signal.

The problem may occur on all vehicles with immobilizer/transponder technology.

Additional electronic keys should not be kept on the vehicle’s key ring, near the ignition lock, or the transponder of the immobilizer.
