Audi Electric Power Steering Rack Repair
Audi Electric Power Steering Rack Specialists
Pro Power Steering assesses, repairs and reconditions electric power steering racks for Audi vehicles with electromechanical steering systems. Where suitable, we work with the original rack and use the vehicle details, steering symptoms, complete diagnostic codes and rack part number to identify the correct application.
Audi used different steering systems, rack generations and software across its models, years and drivetrains. The model name alone is not enough to confirm compatibility. Registration or VIN, model year, drivetrain and the label on the original unit are important.

Common Audi EPS Symptoms We Can Assess
- Red or yellow steering warning in the instrument cluster
- Heavy steering or complete loss of assistance
- Assistance missing at start-up or returning after a restart
- Intermittent assistance while driving
- Uneven, notchy or excessively light steering
- Knocking, play or mechanical noise from the rack, including cases with no stored steering fault code
- Water ingress, corrosion or damaged electrical connections
- Warnings after battery, alignment, suspension or steering work
If steering assistance is reduced or lost, the vehicle may require substantially more effort to steer. Stop using the vehicle if it is unsafe and arrange professional diagnosis or recovery.
Battery voltage, power and earths
Low starting voltage, unstable charging voltage, poor earths or damaged power connections can produce steering warnings and communication faults. Supply voltage and grounds should be checked before the rack electronics are condemned.
Mechanical noise with no fault code
A rack can knock, creak, feel notchy or develop play without storing an electronic fault code. The rack, inner joints, mountings, steering column and nearby suspension components should be inspected so the source of the noise is correctly identified.
Software, calibration and basic settings
Some Audi steering concerns relate to software level, end-stop learning, steering-angle calibration or vehicle configuration. These checks are vehicle-specific and should be considered alongside physical rack inspection.
Audi EPS Fault Codes to Include With Your Enquiry
Send the complete code, suffix, symptom number and the module in which it was stored. A code can describe a mechanical, software, calibration, voltage, communication or internal-control concern; it does not automatically prove that the steering rack must be replaced.
| Code or code family | What it can indicate | What should be checked |
|---|---|---|
| C10AC07 | Steering malfunction or steering mechanical malfunction. Audi service information shows that the meaning and remedy can vary with the model and symptom number. | Record the symptom number, check free mechanical movement and rack condition, then follow vehicle-specific diagnostics. On certain applications, software must be considered before replacing parts. |
| C10ACF0 | Steering end stops not programmed or basic setting lost. | Check calibration, VIN communication, software status and the prescribed end-stop/basic-setting procedure. This code alone does not confirm internal rack damage. |
| B200000 | Power-steering control-module fault. Audi bulletins show that symptom number and software version can change the correct repair route. | Capture extended fault information, software version and symptom number. Power supply, software and the complete test plan should be checked before deciding whether the steering gear requires repair or replacement. |
| 03803 | Steering-angle sensor for power-assisted steering has no or an incorrect basic setting or adaptation. | Check battery voltage, straight-ahead position, wheel alignment, steering-angle data and the correct calibration procedure. |
| No stored DTC | Mechanical wear, knocking, play, stiffness, a notchy feel or another physical rack concern may be present even when the steering control module stores no code. | Inspect the rack mechanically and rule out inner tie rods, mountings, the steering column or joints, suspension components and other possible noise sources. A clear symptom description or video can help. |
| U-codes and voltage codes | Communication loss, invalid data or restricted steering function caused by network, voltage or software conditions. | Send a complete vehicle scan. Battery condition, charging voltage, fuses, power, earths, connectors, wiring and module communication should be tested before attributing the fault to the rack. |
No Audi EPS Fault Code but a Noisy or Mechanical Rack?
Yes, this is possible. Diagnostic trouble codes are mainly generated for conditions the vehicle’s control modules can monitor. They do not detect every worn guide, bush, joint, mounting point or other mechanical source of noise and play.
If the rack knocks, creaks, feels loose, binds or feels notchy but the diagnostic scan is clear, send us the vehicle details and describe when the symptom occurs—for example while parking, changing direction, driving over uneven roads or turning near full lock. A short video or sound recording can also be useful.
A Fault Code Is Not a Complete Diagnosis
Audi diagnostic records can include the code description, symptom number, status, mileage and surrounding operating conditions. That context matters. Low voltage, software, calibration, wiring, network communication and wheel-alignment conditions can create steering-related warnings without proving an internal rack failure.
Our approach: we match the scan information to the vehicle and original rack, review the electrical and mechanical evidence, and explain the appropriate assessment step before repair or reconditioning is agreed.

Audi Electric Power Steering FAQs
Do all Audi models use the same electric steering rack?
No. Steering type, rack generation, software and part number vary by model, year, drivetrain and equipment. We require the vehicle details and original rack number before confirming an application.
Does C10AC07 mean the Audi rack has mechanically failed?
Not necessarily. The complete symptom number and vehicle application matter. Audi service information shows that certain C10AC07 concerns can involve software, while other cases require normal mechanical and electrical diagnosis.
Does B200000 always require a replacement steering rack?
No. The symptom number, software version and extended diagnostic information must be checked. Vehicle-specific Audi procedures can require software or electrical checks before the steering gear is judged faulty.
Can an Audi electric rack be faulty without a fault code?
Yes. A mechanical rack problem can cause noise, play, stiffness or notchy steering without creating an electronic DTC. The rack and surrounding steering and suspension components must be physically inspected.
Can you recondition my original Audi electric rack?
Suitable original units can be assessed for repair and reconditioning. The available work depends on the rack identity, physical condition and confirmed fault.
Do you offer collection and delivery?
Nationwide collection and return can be discussed for suitable units. Contact us before sending the rack so the correct address, packaging and turnaround can be agreed.
