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, if the Engine Control Module uses a Short Coding the Activation is done using Coding-II. If the Engine Control Module uses a Long Coding the Activation is done in (Long) Coding itself. Please also note that there are different Coding Variants for Long 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.
'If you are having trouble finding/calculating the proper Coding using the Coding Assistant Registered Users can email us directly. Make sure to include a complete Auto-Scan from the Car and specify which steps/work you have performed.
