Airbag control unit with part number 6R0959655

What does the airbag control unit 6R0959655 do?

The airbag control unit 6R0959655 controls the restraint system (SRS) for Seat. It measures via the crash sensors what happens in an accident and decides within milliseconds which airbags and seatbelt pretensioners are triggered. After an accident it stores crash data and locks itself.

The unit monitors itself and the rest of the system continuously. It shows faults via the airbag warning light.

The stored crash data record the accident within the unit.

Why does the control unit 6R0959655 fail?

The most common cause is crash data stored after an accident, even without a triggered airbag; they cannot be removed with usual diagnostic tools. Ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes are also possible causes.

Crash data come first, because the unit records them even when no airbag fires.

The other factors concern the electronics: components change with age, solder joints can go cold, and moisture makes contacts corrode. Voltage spikes, for example from a jump start, put additional strain on the circuits.

How can you tell that the 6R0959655 is defective?

The airbag warning light in the instrument cluster lights permanently or intermittently. Added to this are a fault message in the instrument cluster, a missing connection from the diagnostic tool to the 6R0959655, and a fault memory that cannot be cleared. In an emergency the airbags and seatbelt pretensioners may therefore fail to trigger.

The warning light is a standalone warning signal and clearly visible in everyday use.

A fault that the display reports deserves a check before you rely on the system.
