If you're driving an Audi and suddenly see a power steering warning light on your dash, paired with diagnostic codes like B200000 or B200049, you might have a faulty Power Steering Control Module. These fault codes often affect models like the A4, A5, Q5, as well as many others that use electronic power steering systems. These codes are frequently paired with the message “Steering defective! Do not drive vehicle!” and your power steering rack not working. It is tempting to point to the steering rack itself as the part that failed, but in many cases, these issues are caused by an electrical failure within a control module, not a mechanical failure of your steering system. The good news is that fixing a faulty control module is usually much easier and more affordable than the entire power steering rack.

What Do Audi Codes B2000 00 and B2000 49 Mean?

These specific codes point to an internal control module fault. When combined with the steering defective warning message and the vehicle’s power steering not working, they point directly to a failed power steering control module. This module is responsible for communicating with other information in the vehicle and helping manage power-assisted steering. When the module malfunctions, the car loses its ability to control or adjust steering assistance. The result? A steering system that may completely fail to function.

Why Do These Power Steering Codes Show Up?

There are several reasons why your Audi’s power steering module might trigger these codes, and it really comes down to how the module was designed and where it's located. In addition to the normal effects of wear and tear that can cause component failure and broken connections, these modules might experience software issues triggered by collisions or corrupted programming.

While these issues can be intimidating, they usually don’t require replacing the entire steering rack or even the complete module. In many cases, a circuit-level repair is all that’s needed to restore full functionality.

How Much Does It Cost to Fix an Audi Steering Module?

If you take your vehicle to the dealership, the first solution they’ll likely offer is a full steering rack or module replacement, which often includes unnecessary parts and programming. The average quote for this is thousands of dollars, depending on the model, labor costs, and parts availability. That’s a steep price—especially when you consider that the replacement part often has the same flaws as the original and could fail again in the same way.

The best solution is to address the root cause: the circuit board inside the steering control module. Repairing this board eliminates the underlying issue, costs a fraction of the price of a replacement, and ensures you’re not paying to replace parts that are not at fault.
