Application and Function in Active Seats

The presented pump is a key element of the active front seat system in BMW, working in conjunction with the support adjustment mechanism. It is responsible for generating and transmitting power to the system, which dynamically adjusts the seat and backrest support to driving conditions.

This solution improves:

• body positioning during cornering,
• comfort on longer journeys,
• the subjective feeling of seat stability during load changes.

Compatibility and Vehicle Placement

The pump is designed for installation in the front of the vehicle, with the possibility of use on both the driver's and passenger's sides. This facilitates part selection during active seat servicing in BMW 5 and 7 Series, allowing for flexible use of the component depending on the interior configuration.

Thanks to its factory OEM design, proper fitment to factory mounts and correct integration with the seat's electrical system and vehicle controls are ensured.

Characteristics of a Used Component

The offered pump is a used part, sourced from disassembly, which allows for an economical repair of the active seat system while maintaining the original manufacturer's specifications. This type of component is particularly attractive for:

• rectifying seat support system faults without the need to purchase a new module,
• restoring full interior functionality after a failure,
• upgrading seats by replacing them with a version featuring active functions.

Its original BMW origin helps maintain system coherence for the seats and reduces the risk of compatibility issues.

Benefits of Using an Original Active Seat Pump

Using a factory pump actuator in the active seat system translates into a number of practical advantages:

• maintaining operating parameters consistent with BMW's design intentions,
• correct interaction with the seat's control electronics,
• stable operation of the support system under various loads and driving modes,
• the possibility of servicing individual components instead of replacing the entire seat.
