Aston Martin DBX airbag control unit repair⁽¹⁾

What should I pay attention to with Aston Martin DBX airbag control units?

The airbag control unit of the Aston Martin DBX evaluates the crash sensors, triggers the airbags and seat belt pretensioners, and monitors the entire restraint system. If it detects a fault, the airbag warning light comes on in the instrument panel. Airbag24 repairs the control unit you send in for your own DBX.

After an accident, the control unit stores crash data and locks itself. Deleting the crash data is part of the repair at Airbag24.

A defective airbag control unit belongs in the hands of a specialist workshop. Airbags are safety-critical, so do not work on the airbag system yourself. A lit airbag warning light should be checked promptly. The workshop uses a test to establish whether the cause lies in the control unit.

Which Aston Martin DBX generations are there?

The Aston Martin DBX has been built since 2020 in its 1st generation. Series production began in summer 2020, and the model is still in production.

Within the 1st generation, the model year, equipment and software version of the control unit can differ. For the correct repair, the part number on the unit is therefore decisive, not the model name alone.

• 1. Generation (since 2020) – the current DBX series, still being built.

How do I identify my Aston Martin DBX airbag control unit?

The part number on the label of the control unit determines the exact version. Together with the model year and equipment of your vehicle, it allows a clear assignment of the unit. The vehicle identification number (VIN) helps with this assignment.

Note the part number from the label before the control unit is removed. The model year and equipment of your DBX are also important, because they determine which version is installed. If you are unsure, state both in the repair order so that the assignment is unambiguous.

A fault code in the fault memory is an indication, but not proof of a defect in the control unit. Examples of fault codes are:

• 013B: Three crash events stored in the crash memory
• 0005: Battery voltage too low
• 0013: Driver airbag igniter circuit stage 1, resistance too high

What airbag equipment does the Aston Martin DBX have?

The Aston Martin DBX comes as standard with front airbags for driver and front passenger, knee airbags, front side airbags and curtain airbags. The exact number of airbags depends on equipment and model year and is listed in the vehicle handbook.

Sources give different totals for the number of airbags, so we do not state a figure here. The airbags work together with the control unit, which evaluates the crash sensors and coordinates the triggering. The curtain airbags protect the head area along the side windows.

The route to repair: have the fault memory read out at a specialist workshop. The workshop disconnects the battery and removes the control unit. Then create a repair order online and send the unit well packed to Airbag24. Processing usually takes 3–4 working days (checking, repairing, testing). The repair takes place in our workshop in Berlin.

The repaired control unit comes back with all vehicle data and is ready for use immediately after reinstallation — coding or programming is not necessary.
