• supports the safety of the electrical system by physically separating the terminals from the surroundings,
• facilitates the identification of the B-plus power point during diagnostics or when connecting service equipment,
• allows for maintaining a consistent, factory-standard cable routing layout, which facilitates future maintenance work.

For users who care about the technical condition of their vehicle and compliance with the manufacturer's solutions, using the original cover is a reasonable and functional choice.

Condition of the component and practical application

• replacing missing covers after previous interventions,
• restoring the vehicle to a state close to factory specifications.

The cover is intended for users and workshops that expect parts tailored to a specific BMW 7 Series generation, without the need for universal solutions.
