Airbag control unit with part number 7P0 959 655 G

What does the airbag control unit 7P0 959 655 G do?

The airbag control unit 7P0 959 655 G manages the SRS restraint system for Volkswagen. It records the readings from the crash sensors and, in an accident, decides within milliseconds which airbags and seatbelt pretensioners are triggered.

The manufacturer's number Bosch 0285013371 is also printed on the housing. The unit monitors the system continuously and shows faults via the airbag warning light in the instrument cluster.

After an accident it stores crash data and locks itself. Only a repair lifts the lock.

Why does the control unit 7P0 959 655 G fail?

Stored crash data causes the most frequent fault on the 7P0 959 655 G, even when no airbag has deployed, and a normal diagnostic tool does not erase it. The other causes include ageing electronics, cold solder joints, moisture and voltage spikes.

The crash data remains in the memory until it is removed during a repair. Airbag24 takes care of this as part of the repair.

Ageing electronics, cold solder joints and corrosion at plug connections lead to contact problems over time. Voltage spikes arise, for example, from a weak battery or a jump start and put a strain on the unit.

How can you tell that the 7P0 959 655 G is defective?

The airbag warning light in the instrument cluster comes on permanently or intermittently. It is accompanied by a fault message in the instrument cluster, and the diagnostic tool gets no connection to the 7P0 959 655 G.

A fault memory that cannot be cleared is also among the signs. One or more of these signs justify a check without delay.

In a crash, airbags and seatbelt pretensioners may then fail to trigger. Please have the condition clarified promptly.
