__FORCETOC__

== Requirements ==
=== Steering Column Control Module ===

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

* '''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 [[Audi A4 (8E) Steering Wheel#Adaptation|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.<br>

* 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 [[Audi A4 (8E) Steering Wheel#Coding|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 [http://ross-tech.com/contact.html 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.''
