2007 BMW 550i Steering Column Adjust Motor Replacement Cost

This is not an extremely common repair. In fact, these motors are used so infrequently on many vehicles that they tend to last the lifetime of the vehicle. That being said, some luxury models adjust the steering wheel every time the driver door is opened, the key is turned, or a different key is brought into the vehicle. In these cases, the motors are more prone to failure, but still are not likely to fail frequently. Unfortunately, rates of failure for any of these motors or vehicles are unpredictable at best.

When pressing the switch to move the steering wheel position does not result in that action, the technician will listen for signs that power is making it to the motor. If the motor can be heard engaging, the relay is heard clicking, or ratcheting noises are heard from the steering column, the technician will understand that the issue is likely related to the steering column adjust motor, and inspection will begin behind the steering column trim panels. If the motor is either too weak to move the steering column, is separated from the gear, or the gear is damaged, the motor will be replaced.

After the decorative trim for the steering column is removed, the adjustment motors will be exposed, and removing them may be a matter of extensive deconstruction or simply removing fasteners and electrical connectors. Once the motors are installed, electrical connectors will be cleaned before reconnecting. Also, some vehicles will likely require calibration of the motors with the control module to ensure the control module relearns the path and extent of steering column travel.

Electrical diagnostics in general can be problematic, and there are many variables to account for. When electrical problems arise, diagnostics may take several hours to complete, or just a few minutes. This will significantly impact the cost of repairs. Choosing a facility with proper equipment and training for their staff may significantly reduce diagnostic time needed.

The steering column houses circuits for the supplemental restraint system (SRS) airbags, and there is at least one airbag mounted on the steering wheel. If proper procedures for servicing the steering column is not followed, deployment of the air bag or damage to the SRS is possible.

This can be a simple or very difficult repair. For the advanced DIY mechanic with a good understanding of working on and around airbag systems, it is likely possible to complete this repair at home. However, if safe working procedure is unknown, the repair requires extensive deconstruction of the steering column, or diagnostics is not understood, this repair should be left to a professional technician.
