Application and function in the seating system

The knob is designed for installation on the front seats of Audi A4 and S4 models of the 8E and 8H generations, on either the left or right side. It is responsible for precise control of the backrest tilt angle, which has a direct impact on driving comfort, stable back support, and the correct seating position behind the wheel.

The component works with the factory backrest adjustment mechanism, ensuring:

• smooth transmission of hand movement to the adjustment mechanism,
• easy access to adjustments from the driver's or passenger's seated position,
• consistent appearance with other seat trim elements.

Construction and fitment for Audi

As a part from the Other seat parts group, the knob has been designed for specific mountings and the geometry of Audi seats. This means that:

• the shape and profile are adapted to the side of the backrest,
• the mounting interface fits the original adjustment mechanism spindle,
• the ergonomics of the grip allow for comfortable rotation even when wearing gloves.

Thanks to this, the installation process is straightforward, without the need for structural modifications to the seat or the use of additional adapters.

Benefits of using an original pre-owned component

Choosing an original Audi backrest adjustment knob in pre-owned condition is a reasonable compromise between cost and technical compatibility. You receive a component designed by the vehicle manufacturer that:

• maintains factory fitment with the seat mechanism,
• does not introduce additional play or resistance in the adjustment operation,
• maintains the visual consistency of the interior with other seat components.

This is particularly important during repairs following mechanical damage or when replacing a missing element, when you want to preserve the original character of the cabin.

Service purpose and installation

The knob is suitable for both standard repairs and for tidying up the interior after previous unprofessional modifications. The component is dedicated for installation on the front seats on the left or right side, which facilitates part selection when servicing both seating positions in one go.

Due to the factory fitment to the seat structure, the installation can be carried out within the typical scope of workshop tasks, without interfering with the seat structure. This is a good solution for both professional service centers and conscious users who take care of their interior condition themselves.
