Compatibility

For matching 2006-2008 Z4M E85/E86 systems only. Compare the original connector, pin arrangement and sensor configuration with the photos before ordering. This is a three-wire kit; do not substitute it for a two-wire occupancy plug based on chassis name alone. Diagnosis should confirm whether the fault concerns the occupancy mat, buckle circuit, wiring or another SRS component.

Package Contents

• 1 × three-wire seat occupancy diagnostic emulator
• 1 × two-wire seat-belt buckle diagnostic emulator

Seat mat, buckle assembly, SRS control unit and diagnostic scanner are not included.

Important Use Information

For diagnostic/off-road use only. Emulated signals do not restore actual occupant classification or buckle detection. An occupied-seat signal may keep the passenger airbag enabled. Do not place children or child restraints in the front passenger seat while the emulator is installed.

Professional BMW/SRS diagnosis and installation are recommended. Follow the supplied configuration guidance; do not assume a switch setting from a product photo. Stored faults may require suitable diagnostic equipment. A cleared warning lamp does not establish that the restraint system is fully functional.
