Requirements

Steering Column Control Module

There are 3 types of steering column control modules, only 2 of them support cruise control.

  • Lowline
    • Supported Steering Wheels: Standard Steering Wheel (4-Spoke)
    • Supported Features: Trip Computer (does NOT support Cruise Control!)
    • Part Numbers: 8E0-953-549-F 8E0-953-549-S
  • Midline
    • Supported Steering Wheels: Standard Steering Wheel (4-Spoke), Sport Steering Wheel (3-Spoke), Multi-Function Steering Wheel
    • Supported Features: Trip Computer, Cruise Control
    • Part Numbers: 8E0-953-549-L, 8E0-953-549-N
  • Highline
    • Supported Steering Wheels: Standard Steering Wheel (4-Spoke), Sport Steering Wheel (3-Spoke), Multi-Function Steering Wheel
    • Supported Features: Trip Computer, Cruise Control, Steering Wheel Heating
    • Part Numbers: 8E0-953-549-M, 8E0-953-549-P, 8E0-953-549-Q, 8E0-953-549-R


Note: When replacing the steering column control module you may need to learn the vehicle identification number (VIN).


Installation & Wiring

In general the whole retrofit is just plug and play except that one wire needs to be added.

  • Wire T16a/5 from steering column control module to engine control module (see wiring diagram specific your particular car/engine).
  • Install cruise control capable lever (see parts catalog/repair manual).


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.
  • Update the Engine Control Module (J623 / #01) Coding OR via Login/Coding-2
    • 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.
    • As a Rule of Thumb, Control Modules using Long Coding will by activated using Coding while those with Short Coding normally use Login/Coding-2 instead. Due to different Control Modules and Equipment in the Car the actual Coding/Login Table may not be shown here but will automatically be used by the 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.
