OEM part numbers for BMW Active Steering

OEM part numbers identify the correct replacement module. Common BMW numbers include variants used on E60 and E63 models. Always cross-reference VIN and module label before buying.

Tip: ask for the module’s part number and software version when buying used units.

How to install a BMW Active Steering control module

Start with a clear summary: installation requires mechanical fitment and electrical reconnection. Remove the old module from the steering column or rack. Bolt the used control unit into place and reconnect wiring harnesses.

Do not start the car until programming is complete to avoid faults.

Programming and coding requirements

Used BMW steering modules generally require ECU coding. Programming matches the module to the vehicle VIN and options. Tools like ISTA, Carly, or a dealer-level scanner complete the job.

Warning: improper coding can trigger steering faults and safety lights.

New vs used steering control units

Used units cost less but carry uncertain lifespans. New or remanufactured units cost more and often include longer warranties. *Used parts can save 40–70% but inspect warranty terms carefully.*

Choose based on budget, downtime tolerance, and safety priority.

Compatibility checklist for BMW owners

Confirm these before purchase: VIN match, OEM part number match, software version, and physical connector compatibility. Request test reports and return policy proof.

Simple rule: if any of the four items differ, hesitate and verify further.

Used steering control units are a practical way to restore BMW steering function affordably. Confirm part numbers, insist on test reports, and plan for professional programming. Buying from reputable suppliers like Automan Spare Parts reduces risk and shortens downtime.
