Progressive steering in your 2019 Audi Q5 provides a variable ratio that changes how much the wheels turn for a given steering wheel input based on vehicle speed and conditions. When this system malfunctions, steering feel changes noticeably from the responsive character you're accustomed to.
How Progressive Steering Works
Audi's progressive steering uses a rack with variable ratio teeth—closer together in the center for stability at highway speeds, wider spacing toward the ends for quicker response when parking. This mechanical design combined with electric assist creates the progressive feel.
System Components
The system includes the variable-ratio steering rack, electric power steering motor, torque sensor, steering angle sensor, and control module. These work together to provide the appropriate assist level and response throughout the steering range.
Symptoms of Malfunction
Progressive steering issues manifest as uniform rather than variable steering feel, unexpected heaviness or lightness, warning messages about steering, or the steering feeling entirely different from normal operation.
Mechanical vs. Electronic Issues
The variable ratio is built into the rack mechanically and doesn't fail—it's always there. What changes is the electronic assist that enhances the mechanical ratio. Electronic faults affect how the system assists you, not the underlying rack design.
Code 01316 Analysis
Audi code 01316 relates to control module communication errors that can affect progressive steering operation. Communication issues between modules may cause the system to operate in a default mode rather than with full functionality.
Calibration and Updates
Progressive steering may require calibration after certain service. Audi also releases software updates that refine steering behavior. Check for available updates and proper calibration status.
