Seal installation (M5 2018-2022)
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2023 BMW M5, 2022 BMW M5, 2021 BMW M5, 2020 BMW M5, and 2019 BMW M5. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The utmost care must be taken when removing all seals on the vehicle. Incorrect installation can lead to wind noise and water ingress among other things and can affect the ease of closing and opening.
The following instructions only apply to seals without sealant.
Seals with sealant must be replaced each time they are disassembled.
Sealing surfaces must be cleaned.
- In general, the following applies: Seals on the side frame can be fitted and removed any number of times.
- Seals must not be damaged or torn.
- The clamping surface must be compressed manually far enough to ensure that a tight connection on the side flange is still possible. The seal shanks may come in contact with each other slightly. A completely compressed seal is not permitted.
- The seals must always be fitted except in the case of blockages. There is no defined contact pressure.
- A new gasket must be fitted if seals in the trunk lid area are repeatedly fitted and removed (water ingress due to cracked sheet metal).
- Seals must be checked for correct fit after installation. If necessary, seals should be lifted over the adjacent components using the appropriate tool. Neighboring components must not be damaged.
- Seals must be replaced if the metal inlay of the seal is visible (corrosion).
- Ensure the clamping surface is even all round.
- Seals that are installed with plastic clips must fit tightly against the body. If this is not the case, replace the clips or seals.
