1. What is Audi Servotronic and How Does it Work?

Audi Servotronic is a speed-sensitive power steering system that adjusts the level of steering assistance based on the vehicle’s speed; at lower speeds, such as parking or maneuvering, the system provides maximum power assistance, making steering lighter and easier; as the vehicle’s speed increases, the power assistance gradually decreases, resulting in a firmer steering feel and improved stability and control at higher speeds. The system uses sensors to monitor the vehicle’s speed and an electronic control unit (ECU) to regulate the amount of hydraulic pressure applied to the steering system.

The main components of the Audi Servotronic system include:

• Speed sensor: Monitors the vehicle’s speed and sends a signal to the ECU.
• Electronic Control Unit (ECU): Processes the signal from the speed sensor and controls the hydraulic valve.
• Hydraulic valve: Regulates the flow of hydraulic fluid to the power steering system, adjusting the level of assistance.
• Power steering pump: Provides the hydraulic pressure needed for the power steering system.

The Servotronic system uses a solenoid valve to control the amount of hydraulic fluid that flows to the steering gear; the ECU modulates the current to the solenoid valve, which in turn adjusts the size of the opening in the valve; when the opening is larger, more fluid flows to the steering gear, providing more assistance; when the opening is smaller, less fluid flows, reducing assistance.

Audi Servotronic offers several benefits:

• Improved maneuverability: Provides light and easy steering at low speeds, making parking and maneuvering easier.
• Enhanced stability: Delivers a firmer steering feel at high speeds, improving stability and control.
