Airbag control unit with part number 9165624-01

What does the airbag control unit 9165624-01 do?

The airbag control unit 9165624-01 manages the restraint system (SRS) for BMW: it reads the crash sensors, calculates within fractions of a second in an accident when the airbags and seatbelt pretensioners are triggered, and monitors the entire system. After an accident it stores crash data and locks itself.

The housing also carries the manufacturer number Bosch 0285010240.

The system reports faults via the airbag warning light, and the fault memory records them. The unit works in the background and checks the signals continuously.

Why does the control unit 9165624-01 fail?

With the 9165624-01, the most common cause is crash data left in the unit after an accident, even if no airbag was triggered; a normal diagnostic tool cannot remove it. Also possible are aged electronic components, cold solder joints, moisture and corrosion at connectors, and voltage spikes, for example from a weak battery.

Airbag24 erases the crash data during the repair. The other causes can only be narrowed down by examining the unit.

Jump starts and weak batteries cause brief voltage spikes that can stress the electronics.

How can you tell that the 9165624-01 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and a fault in the system has then been detected on the 9165624-01. An error message may also appear, the diagnostic tool finds no connection to the control unit, and the fault memory entry remains.

The warning signal means the system has detected a fault, even if the vehicle is still driving.

In that case, the airbags and seatbelt pretensioners may not be triggered in an emergency.
