The price of new OEM steering modules keeps rising in 2025. Aftermarket and used parts markets matured to fill that gap. Automan Spare Parts offers tested OEM-used steering control units with US shipping and a clear warranty to help drivers save time and money.
What is a steering control unit and why it matters
The steering control unit links driver input to steering assistance and safety systems.
Definition: This module interprets torque, speed, and angle sensors and signals the power assist motor. It also interacts with stability control and driver-assistance systems.
Examples and impact: Faults can disable power assist, trigger warning lights, or degrade handling. For BMW models, a working steering control unit preserves adaptive steering and lane features.
Top benefits of buying used steering control units
Used units deliver savings, tested reliability, and faster repairs when sourced from trusted sellers.
Cost savings and value proposition
You can expect 40–60% lower cost versus new OEM parts for many modules.
Definition: Used steering control units are genuine OEM parts removed from other vehicles and inspected for reuse.
Example: A module priced at $600 new may sell used for $240 to $360 depending on condition and demand. That lowers repair bills drastically.
Quality assurance and testing
Reputable vendors test modules and document results.
Definition: Testing checks electrical integrity, sensor input response, and software compatibility.
Tip: Ask for test certificates and a stated warranty before buying. Automan Spare Parts lists tested modules and a 30-day replacement warranty on the product page (steering control units).
Speed, convenience, and uptime
Local stock and expedited shipping reduce vehicle downtime.
Definition: US-based suppliers often offer 3-day shipping and clear return windows.
Benefit: Faster delivery means shops can complete repairs the same week instead of waiting for backordered OEM parts.
Compatibility and model coverage
Good suppliers provide model-by-model fitment data and VIN checks.
Definition: Compatibility depends on part numbers, software versions, and vehicle options.
Examples: Popular BMW models like the 3 Series, 5 Series, X3, and X5 have strong aftermarket availability for used units. Confirm fitment using VIN and part number cross-reference.
Environmental and sustainability benefits
Reusing functioning modules reduces waste and resource use.
Definition: Refurbishing electronics extends product life and cuts carbon footprint.
Fact: Reusing parts keeps heavy electronics out of landfills and reduces demand for new manufacturing.
Warranty, returns, and post-purchase support
Warranties protect buyers from immediate failures or fitment errors.
Definition: Many sellers offer a 30-day replacement warranty, often with return shipping guidance.
Tip: Keep installation receipts and testing certificates to make warranty claims easier.

How used steering control units are tested and guaranteed
Expect functional and electrical tests plus fitment verification.
Testing steps: Vendors run input/output functional checks, sensor calibration tests, and software compatibility verifications. Ask for test logs or certificates.
Warranty: Look for explicit terms like a 30-day replacement and clear return windows. Automan Spare Parts provides that coverage on the steering control units collection page.
BMW compatibility and model notes
BMW models often share modules across certain model years and trims.
How to verify: Use VIN checks, part-number cross-references, and supplier lookup tools. Request the seller to confirm the module’s ECU software version if possible.
How to choose and verify a used steering control unit
