Aston Martin Virage airbag control unit repair⁽¹⁾

What should I know about Aston Martin Virage airbag control units?

The airbag control unit in the Aston Martin Virage evaluates the crash sensors, triggers the airbags and monitors the entire airbag system. If it detects a fault, the airbag warning light comes on.

After an accident, the control unit stores crash data and locks itself. This is where the repair comes in: Airbag24 repairs your own submitted control unit and deletes the crash data.

A defective airbag control unit affects the function of the entire airbag system. As this restraint system is safety-relevant, inspection and any intervention should be carried out only by a specialist workshop. A professional diagnosis in a workshop is essential.

Which Aston Martin Virage generations are there?

The Aston Martin Virage was built in one series: the VH series from 2011 to 2012. The series comprises the coupé and Volante (convertible) variants.

The Virage name was reintroduced at the Geneva Motor Show in 2011. The car was available as a coupé and as a Volante before production ended in 2012.

• VH (2011–2012): Virage as coupé and Volante, built 2011 to 2012

For this model, the VH series, the year of manufacture and the part number are the key factors in assigning your control unit.

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

The part number on the label of the control unit determines the exact version. Also note the year of manufacture and the equipment of your vehicle before you send in the unit.

The part number is on the label of the control unit and shows which variant is installed. Compare the number with your vehicle data carefully before sending.

Known part numbers for this model, without claim to completeness:

• BD3314B321AA
• CG4314B321BA

A fault code alone does not prove a defect. The fault memory may show codes such as:

• 0005: battery voltage too low
• 013B: three crash events stored in the crash memory
• 0013: driver airbag squib circuit, stage 1: resistance too high

A professional diagnosis in a workshop is decisive for determining the cause.

What airbag equipment does the Aston Martin Virage have?

The Aston Martin Virage came as standard with front airbags for driver and front passenger, as well as side airbags in the front seats. Which further airbags a particular vehicle has depends on its equipment and year of manufacture.

All airbags are controlled by the airbag control unit. It evaluates the sensor data and coordinates deployment in an emergency. A defect in the control unit can therefore affect the entire system.

Whether your vehicle has further airbags, such as head or curtain airbags, can be checked with the vehicle documents or a specialist workshop.

The repair runs as follows: have the fault memory read out. Then disconnect the battery and remove the control unit, ideally with the support of a specialist workshop. Next, create a repair order online and send in the unit. Processing usually takes 3–4 working days (checking, repairing, testing).

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