Airbag control unit with part number 6R0959655A

What does the airbag control unit 6R0959655A do?

The airbag control unit 6R0959655A coordinates the SRS system of Seat. It detects an impact via the crash sensors, determines the airbags and seatbelt pretensioners to be triggered, and checks the system continuously. After an accident, it stores crash data and locks itself.

In the vehicle it works unobtrusively in the background until a fault occurs. Then it makes itself known via the airbag warning light in the instrument cluster.

Why does the control unit 6R0959655A fail?

The most common cause is crash data from an earlier incident, even if no airbag was triggered; a normal diagnostic tool cannot delete it. Airbag24 deletes it during the repair. Other causes are ageing electronic components, cold solder joints, moisture, corrosion and voltage spikes.

During driving this initially goes unnoticed, and crash data alone says nothing about the condition of the rest of the electronics.

The other causes concern ageing, moisture and contact problems at plug connections. Voltage spikes, for example from a weak battery or jump-starting, put additional strain on the electronics.

How can you tell that the 6R0959655A is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, a fault message appears in the instrument cluster, and no connection to the diagnostic tool is established.

Typical signs at a glance:

• airbag warning light stays on permanently or intermittently
• fault message in the instrument cluster
• diagnostic tool finds no connection to the control unit
• fault memory cannot be cleared

In that case, airbags and seatbelt pretensioners may not trigger in an emergency. A prompt check is therefore advisable.
