For Audi owners, the smooth, responsive, and precise handling is an important part of their driving experience. The steering system requires attention to prevent common issues that can compromise the safety and performance.
Routine maintenance is crucial in combating wear and tear from daily driving. Specific proactive steps need to be taken, including checking fluid levels to recognize early warning signs and ensure the Audi’s steering remains reliable.
Causes of Steering Problems In Audi Vehicles
- Low or contaminated power steering fluid: The most common problem is a leak in the power steering system, often caused by a cracked hose, a failed pump, or a compromised steering rack. This causes loss of fluid and pressure. Over time, the fluid can collect debris and particles from wearing components. This contaminated fluid can cause premature wear and damage to the power steering pump and steering rack.
- Faulty power steering pump: The power steering pump is crucial for providing steering assist. A pump that is wearing out can struggle to generate enough fluid pressure, which makes the steering feel heavy. For belt-driven pumps, a loose, damaged, or worn-out serpentine belt can prevent the pump from operating correctly, which leads to loss of steering power.
- Issues with the electronic power steering system: Modern Audi uses electric systems instead of hydraulics. These systems rely on a network of sensors and an electric motor. A fault in the motor, steering angle sensor, or any other component can cause the system to fail because EPS is controlled electronically. Therefore, a faulty fuse, poor wiring, or a weak battery can result in a loss of steering assist.
- Worn-out steering rack: The steering rack converts the steering wheel’s rotation into the motion that turns the wheel. The internal components can wear out over time due to high mileage, causing leaks and excessive looseness in the steering. The seals on the steering rack can dry out and crack, allowing the power steering fluid to leak out. This reduces the hydraulic pressure needed for smooth steering.
Symptoms to Watch for In Your Audi
- Heavy or Stiff Steering: Certain symptoms include the steering wheel requiring more effort to turn at low speeds or when parking. This indicates low power steering fluid, a failing pump in the hydraulic system, or an electronic fault in the EPS system.
- Unusual noise while turning: A high-pitched whining sound when turning the wheel is a sign of low fluid or a struggling power steering pump. Loud knocking sounds that occur when turning the wheel can indicate a problem with the steering rack, tie rod ends, or ball joints.
- Steering wheel vibration: The steering wheel vibrates when turning or travelling over uneven roads. It can be a sign of a failing power steering pump or a worn-out steering rack. It can also be caused by unbalanced tires or a misaligned wheel.
Solutions for Audi Steering Problems
- Fluid replacement and leak repair: If the issue is low or contaminated fluid, then a professional can flush the oil and replace it with the correct type recommended for the Audi model. For any leaks, they will inspect and replace the faulty hoses, pump seals, or reservoir.
- Component replacement: If any component, such as the power steering pump, steering rack, or a key suspension part, has failed, then replacement is the best solution.
- Module Reconditioning: For any electronics problem, diagnosing from the specialists who offer reconditioning services for the EPS control module is necessary. This is a more cost-effective solution than a complete component replacement, and the vehicle’s existing data will be preserved.
- Software Updates: In some instances, an EPS malfunction is a result of outdated software. In this case, our mechanics, who possess dealer-level technical knowledge, can perform a software update to resolve the issue.
- Diagnosing hydraulic power steering problems involves checking the fluid level, inspecting the fluid’s condition, looking for leaks, and listening for unusual pump noises.
- Diagnosing electric power steering problems includes scanning for any faulty codes and performing a hard reset.
- Diagnosing mechanical steering and suspension problems includes checking tire pressure and alignment, inspecting suspension components, and testing for steering rack play.
