Cruise Control Retrofitting (6R)

Requirements

Central Electronics Control Module

There are 5 Types of Body Control Modules (BCM/J519), only 3 of them support Cruise Control. The installed Type can easily be determined by the Control Module Part Number. Higher equipped Types always include the Options from the lower equipped ones. When replacing a Body Control Module (BCM/J519), make sure to Disable 'Production Mode' by using the Adaptation Function once the new Module is installed. Otherwise Functions like Remote Control and Automatic Windows may not work as expected.

Configuration

The following Activations are necessary to ensure that the newly fitted parts are properly recognized and are ready to use.

• Update the Central Electronics Control Module (J519 / #09) Coding.
  • Due to different Control Modules and Equipment in the Car the actual Coding Table is not shown here but will automatically be used by the Long Coding Assistant once you access the Function using VCDS.
• Update the Engine Control Module (J623 / #01) Coding.
  • Make sure that the Engine is NOT running, otherwise the new Coding will be rejected. Models equipped with Start/Stop System do have a Shutoff Switch/Button which will deactivate the Start/Stop Function.
  • Due to different Control Modules and Equipment in the Car the actual Coding Table is not shown here but will automatically be used by the Long Coding Assistant once you access the Function using VCDS.

If you are having trouble finding/calculating the proper Coding using the Long Coding Assist please Contact us directly. Make sure to include a complete Diagnostic Protocol (Auto-Scan) from the Car and state which steps/work you have performed yet.
