Airbag control unit with part number 5C0959655Q

What does the airbag control unit 5C0959655Q do?

The airbag control unit 5C0959655Q controls the restraint system in vehicles from Volkswagen. Based on the crash sensors, it decides within milliseconds in a crash which airbags and seatbelt pretensioners are triggered, and it monitors the system continuously. It indicates faults via the airbag warning light.

After a crash, the unit stores crash data and locks itself. To do this, the control unit works together with sensors, wiring and triggering elements.

Why does the control unit 5C0959655Q fail?

The most common cause with 5C0959655Q is stored crash data, even if no airbag has deployed. These can not be erased with a standard diagnostic tool, but Airbag24 erases them during the repair.

Aged electronic components may also be a cause, as their condition deteriorates over time.

Moisture, corrosion at plug connections and faulty solder joints disrupt the connections within the circuit.

Voltage spikes, for example from a weak battery or a jump start, can also strain the electronics.

How can you tell that the 5C0959655Q is defective?

A fault in the 5C0959655Q shows up as the airbag warning light in the instrument cluster, which lights up constantly or intermittently. In addition, a fault message appears, the diagnostic tool cannot find the control unit, and the fault memory cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may fail to deploy if the control unit is defective. A prompt check is therefore worthwhile rather than waiting.
