From Ross-Tech Wiki

Jump to: navigation, search

Retrofitting a Cruise Control System (CCS) into a Audi A4 (8K), Audi A5 (8T) and Audi Q5 (8R) requires multiple steps.


These instructions do not cover mechanical/electronic details, they will only list the diagnostic side (coding etc.). Additional details for the mechanical/electronic work needed are part of the retrofitting instructions provided by the parts supplier (i.e. trailer hitch retrofits) or can be found in the factory repair manuals and wiring diagrams (see Ross-Tech FAQ 1.13).


Requirements

  • The proper Steering Column Lever/Stalk needs to be installed
  • The proper Steering Column Module (J527 / #16) needs to be installed

Please refer to the Parts Catalog for a List of compatible Parts or contact your Retrofitting Kit Supplier for details.

Configuration

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

  • Update the Steering Column Control Module (J527 / #16) 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.
    • For Engines with a 2nd Engine Control Module (J624 / #11) this needs to be coded as well.
    • 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.
