BMW E90 E87 E84 Passenger Dashboard Airbag 3408 1150 B - Used Original Parts

Diagnosis and Common Symptoms

When dealing with the BMW E90, E87, or E84 chassis, a passenger dashboard airbag replacement is typically required for two reasons: a deployment during a collision, or an internal hardware failure. If the unit has not deployed, a failure will trigger the red airbag warning light on the instrument cluster and an iDrive message displaying a "Passenger restraint system malfunction." Scanning the vehicle with ISTA or INPA will usually reveal fault codes such as 93A9 or 93AA, which indicate that the resistance value for the passenger airbag igniter circuit (Stage 1 or Stage 2) is too high or too low. If the wiring harness between the ACSM/MRS crash module and the airbag checks out, the internal igniter has failed. Replacing the unit with a verified Genuine part restores the circuit integrity and ensures passenger safety.
