DS Automobiles airbag control unit repair(7)
Is the airbag warning light on in your DS? Choose your model, remove the control unit and send it to us for testing and repair.
What should I consider with DS Automobiles airbag control units?
With a DS Automobiles airbag control unit, the exact model series and year of manufacture matter, because hardware, part number and equipment differ from model to model. We repair your removed control unit in our workshop in Berlin and erase any stored crash data.
The DS name was introduced in 2009 as a premium line of Citroën and became a brand in its own right in 2014. It first belonged to the PSA group and is now part of Stellantis. In these vehicles the airbag control unit is the central component: it evaluates the signals from the sensors and decides on deployment in an emergency.
If the airbag warning light stays on, a fault may be stored in the control unit, for example after an accident or because of an internal defect. Typical fault codes are B0091 (fault in the left satellite line, i.e. the side impact sensor: open circuit or internal sensor fault) and B00D5 (fault at the passenger airbag deactivation indicator). A code only names the area of the fault; the exact cause is found by testing the control unit.
The repaired control unit comes back with all vehicle data and is ready for use immediately after refitting. The airbag system is safety-critical: have any work on it carried out only by a specialist workshop and do not try to deactivate it yourself.
Which DS Automobiles models are there?
In our shop you will find airbag control units for the following DS Automobiles models, each in the matching model series.
- DS Automobiles DS 3
- DS Automobiles DS N°4
- DS Automobiles DS 7
- DS Automobiles DS 9
- DS Automobiles DS N°8
The series range from the DS 3 Crossback (2019-2022) and the DS 7 Crossback (2017-2022) through the DS 9 (2020-2024) to the newer DS N°4 and DS N°8 (from 2025). Different control units are used in each series, so matching by part number and year of manufacture is important.
How do I identify my DS Automobiles airbag control unit?
You can identify your DS Automobiles airbag control unit by the part number on the unit's label. Model, year of manufacture and vehicle identification number also help to match the correct control unit.
The installation location differs from model to model. Removal should be carried out by a specialist workshop, because the airbag system is safety-critical and must not be damaged. Note down the part number from the label before you pack the unit.
Send the removed control unit to Airbag24 by parcel, well packed. We test it, fix the fault and send it back by UPS.
What airbag equipment does DS Automobiles have?
The airbag equipment of DS Automobiles depends on the model, year of manufacture and trim level. Modern vehicles in this class generally have front, side and curtain airbags, which may be supplemented by further modules depending on the vehicle.
Which airbags are fitted in your vehicle is shown in the vehicle documents. The more modules and sensors a vehicle has, the more lines and messages the control unit monitors. The passenger airbag deactivation indicator, to which code B00D5 belongs, is one example.
A defective control unit can impair the deployment of the airbags in an emergency. Have an illuminated airbag warning light checked promptly.
