Purpose and function of the seal

The presented seal has been designed specifically for the Audi SQ5 FY family of models, intended for use on the front driver and passenger side doors. Its purpose is to:

• limit the penetration of water and moisture into the door interior and cabin,
• reduce wind noise at higher speeds,
• stabilize the window movement within the door frame,
• maintain an aesthetic contact line between the upholstery and the door frame.

Thanks to its properly selected profile and flexibility, the seal helps maintain factory ride comfort and the proper acoustic insulation characteristic of Audi models.

Construction and fitment for Audi SQ5 FY

The inner door seal is a structural element matched to the geometry of the Audi SQ5 FY front doors. The cross-sectional shape and mounting method are prepared to work with the factory mounting points in the doors, which facilitates service and the replacement of worn components.

The appropriate stiffness and elasticity of the material ensure:

• secure adhesion to the door frame and trim elements,
• maintenance of a seal within typical door operating ranges (opening, closing, slight body deformation),
• reduction of squeaks and unwanted noises while driving.

Vehicle placement and service application

The element is intended for installation in the front door area on the left and right side. This placement designation allows the seal to be treated as a service part both when replacing a single element and when symmetrically replacing both front door seals, e.g., after a collision, bodywork repairs, or due to advanced wear and tear.

In workshop practice, this type of seal is replaced in situations such as:

• the appearance of water leaks in the front door area,
• increased wind noise at higher speeds,
• mechanical damage after removing the upholstery or window.

Product characteristics and condition

The offered seal is a part originating from an Audi vehicle, which means it maintains factory fitment and compatibility with the door construction of the SQ5 FY model. As a secondary market item in used condition, it provides a cost-effective solution while maintaining the original geometry and manufacturing standard provided by the manufacturer.

Choosing an original inner door seal allows you to reduce the risk of assembly problems, leaks, or improper window guidance, which may occur when using elements with a universal profile.

Selection by OEM number and purchase support

When selecting a seal for a specific version of the Audi SQ5 FY, it is crucial to compare the OEM number and the placement on the vehicle. In case of doubt, it is worth using the Vehicle Identification Number (VIN) or consulting a mechanic to confirm the compatibility of the part with the specific door and equipment configuration.
