In this guide, we look at common problems that trigger the restraint system malfunctions and how to diagnose the problem yourself. For this procedure, you will need a BMW scanner. Depending on the model, there are front, side and curtain airbags. The steering wheel and the passenger-side dashboard hold front airbags. These are activated in case of a frontal impact to minimize head and chest injuries. Side airbags are installed within front seats and protect passengers during side impacts or vehicle rollovers.

Curtain airbags have a similar protective role as side airbags, but also minimize the risk of injury from broken glass. These airbags are located between the A and C pillars. If an airbag has previously deployed it will trigger the restraint system malfunctions warning light.

But a more common issue is the wire harnesses that connect to any of the airbags. Wires to the airbag can get damaged during a minor accident or previous repair work. An SRS module controls the restraint system. It uses impact sensors to determine the severity of a collision.

When the system detects sufficient deceleration, it takes action within about 20 milliseconds. If the force of the impact is low, the control module may deploy the seatbelt pre-tensioners only and display restraint system malfunction on the dashboard. In case the impact force is high enough, airbags will also deploy at about the same time. A signal ignites a chemical reaction, producing a rapid expansion of nitrogen gas, inflating the airbag within about 30 milliseconds.

Besides these features, most BMWs from onwards have a system that monitors when a passenger is on the seat and their weight. This sensor is, in fact, an electrical matt installed into the base of the passenger seat. As it carries the whole weight of the passenger, it usually fails as the years go by.

It starts as an intermittent error, only to get worse with time.

Although there are emulators that can solve this problem, these make the passenger airbag active all the time. Although time-consuming and costly, the best solution is to replace the sensor. Foreign objects pushed under the seat can easily damage these connectors, especially if the seat is moved back and forth frequently.

Other components, such as airbags or seat belt tensioners, rarely fail on their own. However, they can get damaged or activated during assembly or disassembly if not handled properly. Seat belts prevent sudden forward movements and ensure passengers are in the correct position for airbag deployment.The E61 wagon followed shortly there after. View My Garage.
