• repairing airbag system errors related to seat occupancy,
• replacing a damaged mat after upholstery work,
• restoring seat completeness after disassembly or interior upgrades.

Using an original component from disassembly promotes the maintenance of consistent electrical parameters and compatibility with factory BMW control unit software.

Importance of proper selection and installation

When replacing the passenger seat occupancy sensor mat, it is crucial to match the component to the specific seat configuration and vehicle equipment version. Proper selection ensures:

• absence of errors and warning messages on the instrument cluster,
• correct activation of the passenger airbag,
