Mercedes-Benz W221 Dashboard Passenger Airbag Unit - Used Original Parts
Diagnosis and Common Symptoms
On the W221 S-Class platform, the passenger dashboard airbag module (SRS unit) is a critical restraint component monitored continuously by the central SRS control unit (N2/8). When this module develops a fault - whether from an internal squib circuit failure, resistance drift, or physical damage to the dash-top housing - the system triggers a hard fault code, commonly logged as B1004 series or related "Passenger Airbag Circuit Malfunction" entries readable via STAR Diagnosis (Xentry/DAS). Drivers typically report the SRS warning lamp illuminating solid or flashing on startup, an audible chime accompanied by a "SRS" or "Airbag" message on the instrument cluster, and in many cases the "PASSENGER AIRBAG OFF" indicator failing to function correctly or staying permanently lit/unlit regardless of seat occupancy. In some vehicles, this fault also causes secondary alerts related to the Passenger Occupancy Detection System (PODS/BAS) since the airbag module and seat sensor communicate on the same restraint circuit. Left unaddressed, a faulty module can prevent the vehicle from passing SRS self-check on startup, and in worst cases, may not deploy correctly during a collision - making proper replacement with a tested, functioning unit essential for restoring both safety and dashboard indicator accuracy.
Introduction
This is a Genuine Used Mercedes-Benz W221 dashboard passenger airbag unit, removed directly from a donor vehicle during full disassembly and carefully inspected before listing. Every unit we offer goes through resistance and continuity checks to confirm it is Tested Working prior to shipment, giving buyers confidence they're receiving a functional restraint component rather than an unknown-condition part. Since this is a Genuine Mercedes-Benz component, fitment and connector alignment match your original dashboard assembly without modification. We stand behind every listing with real inspection data, not just a generic description.

Frequently Asked Questions
Q: What symptoms indicate failure? A: A persistent SRS warning light, an airbag-related fault message on the instrument cluster, or the "PASSENGER AIRBAG OFF" indicator behaving incorrectly are the most common signs pointing to this specific module.
Q: Does this require coding? A: In most cases, no coding is needed since this is a passive restraint component; however, we recommend clearing fault codes with STAR Diagnosis (Xentry/DAS) after installation to confirm the SRS system recognizes the replacement and resets properly.
Q: Is this original? A: Yes, this is a 100% Genuine Mercedes-Benz part, removed from an actual W221 donor vehicle - not an aftermarket reproduction.
