Troubleshooting the 00473 Audi Fault Code: A Step-by-Step Guide

Here’s a structured approach to diagnosing and resolving the 00473 Audi fault code:

1. Scan for Fault Codes: Use a diagnostic scanner (like VCDS) to confirm the presence of the 00473 code and identify any other related codes. This is crucial for accurate diagnosis.
2. Check Power Steering Fluid Level: Low power steering fluid can trigger this code. Top off the fluid if necessary and check for leaks.
3. Inspect Power Steering Pump: Examine the power steering pump for signs of damage, leaks, or unusual noises. A failing pump often needs replacement.
4. Check Wiring and Connections: Inspect the wiring harness and connectors associated with the power steering system for damage, corrosion, or loose connections. Repair or replace any faulty components.
5. Examine the Steering Rack: The steering rack can also contribute to this issue. Look for leaks or damage.
6. Test the Power Steering Control Module: If all other components check out, the control module itself might be faulty and require replacement or reprogramming.
