Is Your Audi Losing Steering Smoothness? Causes and Cures for Power Steering Assist Malfunction

Malfunctioning steering assist makes your Audi difficult to maneuver and causes it to feel stiff or unresponsive while turning. There are typically only four main reasons for this issue such as hydraulic issues due to low fluid levels, belt and pump issues, electrical problems or malfunctioning sensors or modules. In today’s Audis steering assist can be hydraulic or electric and knowing which system your car will help pinpoint the exact cause.

What's Wrong with Audi's Power Steering?

Cars from the past had conventional power steering which used hydraulic fluid to assist wheel rotation. However, the current generation of Audi cars now uses a different and quite sophisticated mechanism which is Electric Power Steering.

The Electric Power Steering uses an electric motor and several computer modules. It provides precise steering, saves fuel and adjusts the steering feel based on your car's speed and the road surface.

Audi Power Steering System Warning Signs

• You may notice lights that say "Power Steering Assist Malfunction" or a steering wheel symbol.

• Your steering wheel gets tough to handle particularly when driving slowly.

• There could be unusual whining, squeaking or grinding noises whenever you rotate the steering wheel.

• The steering no longer operates smoothly.

• Moist spots under your vehicle indicate that your power steering fluid is leaking.

Why Do Audis Have Issues with Power Steering?

Hydraulic System Failure - An Audi that is equipped with a hydraulic system uses power steering fluid. It becomes critical when there is any leakage of the fluid, its quantity is low or the fluid itself becomes contaminated.

Symptoms you may notice include power loss, unusual noises during turning and even total failure. You need to look for any fluid accumulation under your vehicle or check the amount of fluid left in the tank.

Malfunctioning EPS Motor - A newer model will have an electric power steering motor installed. It fails when the motor overheats, malfunctions, becomes waterlogged or is defective.

Sensors or Electrical Glitches - To work correctly the EPS uses a set of sensors and computers. If there is a malfunction in the system's wiring or a sensor goes bad then the warning lights trigger.

Faulty Steering Rack - The steering rack connects your steering wheel to your wheels in your vehicle. When there is any problem with the rack's inner components such as sticking or wear then steering becomes difficult to use. Hydraulic and EPS systems share similar problems with the steering rack.

Battery or Charging System Issues - EPS systems are dependent on electricity. If your battery's capacity decreases or the charging system produces less energy due to corrosion at the terminals or a weak battery then the steering system won't receive the required electricity which can cause problems.

Software Problem - In today's advanced technology many car systems run on computers. After a system update or component replacement the power steering may not work properly due to a software issue.

How to Identify the Issue with Steering in Your Audi Car

Power Steering Fluid - Check for leaks from this part and ensure it has enough fluid.

Check Diagnostics Trouble Code - Connect your vehicle to a code reader to display any trouble codes.

Examine Alternator & Battery - Test your alternator's output and your battery voltage.

Visual Inspection - Check your car for any damage to the wiring, sensor systems and other equipment.

Unusual Sounds - Notice any unusual sounds, vibrations and feel when steering.

Audi Professionals - If you have some complex issues or a steering rack failure then consult an expert.

Avoiding Power Steering Assist Problems in the Future

Scheduled Maintenance - Don't forget to check fluid levels, battery status and the charging system's functionality.

Electrical Systems - Always replace the battery when needed and ensure your alternator works properly.

Post-Repair - If any electronic work is done to your vehicle, then always have the appropriate modules checked and possibly reprogrammed.

Don't Hesitate to Act - Any flashing warning lights, unusual sounds or changes in steering system operation should be addressed immediately to avoid costly repairs later.
