Purpose and function in the Audi Q5 FY body

The presented sill seal is designed for installation in the front right door, in the lower part of the door opening. It is responsible for a tight connection between the sill and the door, which:

• limits the ingress of moisture and contaminants into the body interior,
• reduces the risk of corrosion in the sill area,
• supports the maintenance of proper cabin acoustic insulation,
• stabilizes the door line relative to the sill, improving the feeling of solid closing.

Thanks to the proper profile, the seal works with the factory door and sill construction, which translates into repeatable, secure sealing every time the door is closed.

Construction and material properties

The element is made of flexible rubber adapted to work in variable weather conditions, typical for vehicle operation. The material used:

• retains elasticity at low and high temperatures,
• is resistant to typical road agents (moisture, salt, dirt),
• allows for repeated opening and closing of the door without losing its working shape.

The seal profile has been designed to ensure even pressure along the entire length of the sill, which minimizes local leaks and improves daily vehicle usage comfort.

Benefits of using an original sill seal

Using a dedicated sill seal in the Audi Q5 FY allows for maintaining the structural integrity of the body. In practice, this means:

• proper fit to the shape of the sill and door without the need for modifications,
• maintenance of the factory seal contact line,
• reduction of wind noise in the front door area at higher speeds,
• more stable paint protection in the lower part of the door opening.

This solution is particularly beneficial for post-accident repairs, replacing corroded elements, or restoring original sealing after years of operation.

Condition of the element and service application

The seal comes from disassembly and is intended for reinstallation in a vehicle where it is necessary to replace a worn or damaged element. This type of part will work well both in routine repairs and in comprehensive renovation of the sill area, where maintaining the factory finish character is important.
