Aston Martin DB9 airbag control unit repair⁽¹⁾

What should be considered with Aston Martin DB9 airbag control units?

The airbag control unit of the Aston Martin DB9 evaluates the crash sensors, triggers the airbags and seat belt tensioners, and monitors the entire restraint system. If it detects a fault, the airbag warning light comes on. Airbag24 repairs the control unit you send in, where necessary including the erasure of crash data after an accident.

The Aston Martin DB9 is a sports car from the British manufacturer Aston Martin and was built from 2004 to 2016. In the vehicle, the airbag control unit is a central component of passive safety.

After an accident, the control unit stores crash data and may lock itself. Whether and how a unit can be repaired only becomes clear after inspection in the workshop. Work on the airbag system should therefore be left to a specialist workshop, as the airbag is safety-critical.

Which Aston Martin DB9 generations are there?

The Aston Martin DB9 was built in the VH series from 2004 to 2016. This series covers the entire production period of the model.

• VH (2004–2016) – the series of the Aston Martin DB9 across its entire production period

For assigning the control unit, the series alone is not sufficient; the model year and part number are therefore also decisive.

How do I identify my Aston Martin DB9 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 DB9, the matching unit can be narrowed down clearly.

Compare the number with the following part numbers known for this series. The list makes no claim to be complete:

• 30773787
• 30795181
• 30773786
• 31334739

Examples of fault codes for this series are 0131 and 0132 (internal component faults at system start-up) and 013B (three crash events stored). A single fault code, however, does not prove a defect in the control unit. The more complete the model year and part number are, the better the repair can be prepared.

What airbag equipment does the Aston Martin DB9 have?

The Aston Martin DB9 has front airbags for driver and front passenger as well as side airbags for the front seats. Which further airbags are fitted depends on model year and equipment.

These details are based on equipment descriptions. A complete overview per model year is not listed here. Whether a particular DB9 has further airbags can be checked in the vehicle documents, the equipment list or the vehicle identification number (VIN).

The route to repair: have the fault memory read out, disconnect the battery and have the control unit removed properly, preferably by a specialist workshop. Then create a repair order online and send the control unit in by mail-in procedure. The repair takes place in our workshop in Berlin; processing usually takes 3–4 working days: checking, repairing and testing.

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