Application and function in the vehicle

The presented actuator is responsible for adjusting the front seat backrest in BMW 6 Series and X5 E53/E64 generation vehicles. It is mounted in the front cabin area and works with the seat mechanism, allowing for smooth changes to the backrest tilt angle according to user settings. A properly functioning actuator contributes to:

• stable maintenance of the selected backrest position while driving,
• greater comfort on long journeys thanks to seat position adjustment,
• safer back support for the driver and passenger.

Construction and fitment for BMW

The actuator has been designed specifically for BMW front seats, maintaining factory mounting points and the operating geometry of the mechanism. Thanks to this:

• it fits the seat structure without the need for modifications,
• it works with original rails and adjustment elements,
• it maintains technical consistency with other interior components.

As an element from the Seats and benches group, it is intended for operation in conditions typical for a vehicle interior, taking into account the mechanical loads resulting from daily seat use.

Condition, origin, and benefits of choosing a used part

The offered actuator is a used part, sourced from a dismantled BMW vehicle. Choosing an original second-hand component allows you to maintain compliance with the manufacturer's factory specifications while reducing the costs of repair or interior modernization. For many BMW users, this is a reasonable compromise between quality and budget, especially in the case of components responsible for seating comfort.

Installation and technical aspects

The actuator is intended for installation at the front of the vehicle, within the seat structure. When replacing, it is recommended to:

• remove the seat in accordance with the BMW service procedure,
• check the condition of the backrest adjustment mechanism and rails,
• verify correct operation after installation – smooth movement, no play, and no unwanted noises.

Using an original element from the same construction group minimizes the risk of fitment issues and ensures predictable behavior of the adjustment mechanism.

Expansion and modernization of the BMW interior
