Purpose and vehicle placement

The presented seal has been designed specifically for the rear body section of the Volkswagen Passat CC and is suitable for installation on both the left and right sides. Its placement on the vehicle covers the lower, outer section of the rear door, where the component is responsible for maintaining proper sealing between the door and the sill and side panel.

This solution allows for proper water drainage from the door area, reduces corrosion in the sill zone, and improves acoustic comfort inside the vehicle. Precise fitment for the rear left and right sides facilitates installation and minimizes the risk of leaks after replacing the component.

Technical and functional characteristics

The outer lower seal works in direct contact with the door edge and body elements; therefore, its profile and material hardness are selected to ensure stable adhesion during repeated opening and closing of the door. The design provided by the vehicle manufacturer allows for maintaining factory assembly clearances, which is essential for proper door closing and the absence of rattles while driving.

This component performs several key functions:

• seals the lower edge of the rear door against water and road debris,
• limits the ingress of road noise into the cabin,
• supports the anti-corrosion protection of sills and lower body parts,
• stabilizes the door line relative to the body, improving the overall aesthetics of the vehicle's side.

Thanks to the use of an original design solution, the seal works with existing mounting points and does not require any modifications to the body or doors.

Component condition and service application

The offered seal is a used component, which makes it a reasonable choice for maintenance repairs and restoring door sealing after a collision or bodywork intervention. In practice, it will work well both as a replacement for a worn, perished seal and when completing missing parts after body repairs.

Replacing this type of component is often recommended when symptoms appear such as increased cabin noise, moisture in the sill area, traces of water on inner seals, or problems with proper door closing. Using an original Volkswagen seal reduces the risk of mismatching, which is typical for universal rubber profiles.

Benefits of using an original Volkswagen seal

Choosing the right outer lower seal has a direct impact on the durability of the body and the comfort of using the vehicle. In the case of the Volkswagen Passat CC, it is particularly important to maintain sealing in the rear part of the cabin, where dirt and water from the rear wheels intensively affect the sills and lower door edges.

The main advantages of using this component include:

• maintaining factory geometry and door lines relative to the body,
• reducing the risk of corrosion in the sill zone and lower edges of the panels,
• improving acoustic and thermal comfort inside,
• easier diagnostics of potential leaks after body repairs.

By choosing an original seal from the Door seals group, the user gains a component designed specifically for the given model, which translates into stable performance over a long period of operation.
