Airbag control unit with part number P32269179

What does the airbag control unit P32269179 do?

The airbag control unit P32269179 is the central control unit of the restraint system (SRS) for Polestar. It processes the signals from the crash sensors and decides in an accident which airbags and seatbelt pretensioners are triggered. It also monitors the system permanently and reports faults via the airbag warning light.

After an accident the unit stores crash data and locks itself. Both happen automatically.

This function is indispensable for protection in an emergency.

Why does the control unit P32269179 fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered; a normal diagnostic tool cannot erase it. Aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes, for example from a weak battery or a jump start, are also possible causes.

The stored crash data cannot be reset with common tools, and that is precisely why many fault searches in the wiring harness come to nothing.

The other causes mainly concern components and connections inside the unit itself.

How can you tell that the P32269179 is defective?

The airbag warning light in the instrument cluster is permanently or intermittently on, and an error message appears in the instrument cluster. The diagnostic tool finds no connection to the control unit, and the fault memory cannot be erased. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

These signs belong together and point to a test of the control unit. Do not ignore the warning light, because it indicates the problem.

Compare the part number on the label of the removed unit with this page, because that way you ensure it is the right unit. Have the fault memory read out beforehand without fail, because only that shows whether the control unit itself is defective or a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers P32315772.

How does the repair of the P32269179 work?

Processing at Airbag24 usually takes 3–4 working days. Beforehand, have the fault memory read out, enclose the printout, disconnect the battery and remove the control unit; then create the repair order and send in the unit.

This order protects you and must be followed when removing it. Pack the unit only once the order is in place.

Airbag24 tests the unit, replaces defective components, erases stored crash data and carries out a function test. Afterwards, your own unit is returned to you. Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.

How does the control unit P32269179 get to Airbag24?

You send the unit as a parcel or book a UPS collection for an extra charge. After the repair, Airbag24 sends it back to you by UPS.

Put the printed repair order into the parcel and pack the unit shock-proof.
