VW Golf (1K) Steering Assist
From Ross-Tech Wiki
Channel 001: Characteristic Curve
Depending on the Steering Aid Generation/Software Version this Channel may or may not be active. Generation 1 and early Generation 2 still allowed switching between up to 16 different predefined Characteristic Curves, while later/updated Generation 2 and 3 do not and the Adaptation Channel is being inactive/unavailable.
The Control Module Identification lists the currently selected Characteristic Curve. The first Example shows an early Generation 2 with a currently active Curve #9 indicated by Kl. 9 in the Component Field, while the second Example shows a Generation 3 which cannot be altered. As a rule of thumb, if the Number of current Setting is larger as 20 this Setting/Channels cannot be altered directly.

If the Identification shows 000 as current Setting it means that no Characteristic Curve has been uploaded and the System is working with a Linear Curve instead. This is a common Situation after the Steering Rack has been replaced, for further Details please see Steering Aid (J500) Control Module Replacement

Channel 002: Malfunction Indicator Lamp (MIL)
Channel 003: Driver Steering Recommendation (DSR)
Channel 004: Installation Park Steer Assist
Channel 005: Torque Steer Compensation (TSC)
The Torque Steer Compensation (TSC) is only being activated for Front-Wheel-Drive (FWD) Models which have a high powered Engine. This Function prevents the Car from leaning into one Direction while Accelerating in Combination with powerful Engines and unequal Lenghts Drive Shafts.
Channel 006: Installation Lane Assist
Channel 008: Installation Adaptive/Dynamic Chassis Control (DCC)
Channel 009: Steering Angle Sensor
The Adaptation Channel determined the Functionality of the internal Steering Angle Sensor. Depending on the Combination of Steering Aid and Brake Electronics the internal Steering Angle Sensor needs to be deactivated.

Important Note: This procedure ONLY applies to Models with Conti/Teves MK70 ABS/ASR.
This Procedure does NOT apply to Conti/Teves MK60, MK60CE, MK60EC1 and similar ABS/ASR/ESP systems. Check the Vehicle specific Diagnostic Procedures pages for each ABS System page with documentation.
Note: After successful basic setting, the Steering Limit Stop needs to be adapted too.

Checking Steering Torque Sensor (G269)
Turn the Steering Wheel multiple times completely to the left and right. The Torque Values should change.
After Replacing this Control Module several Steps have to be performed in the following Order:
Characteristic Curves need to be uploaded with the Factory Tool which has the latest Brand Version installed as well as access to the latest Flash Updates. Unless you have a Factory Tool which meets these Requirements the only Solution to accomplish this Step is to take the Car to the Dealer and have them perform this.
In case you are having trouble with procedure please contact us directly and we will assist you with the Coding Process. Every inquiry on this topic has to include a full Auto-Scan as well as which parts have been replaced and why, also make sure the Auto-Scan includes the complete VIN of the vehicle in question.
