What should I know about DS Automobiles DS 4 airbag control units?
The DS Automobiles DS 4 airbag control unit evaluates the crash sensors, triggers the airbags and belt tensioners, and monitors the entire airbag system. If it detects a fault, it reports it via the airbag warning light. After an accident, it stores crash data and locks itself.
If the airbag warning light comes on, the control unit is not always the cause. However, a defective control unit can impair the function of the entire airbag system. The airbag system is safety-critical, so any check or work on it belongs in a specialist workshop.
Airbag24 repairs your own control unit, which you send to us, in our workshop in Berlin. Whether a particular fault can be repaired only becomes clear once the unit has been examined. After an accident, the stored crash data is erased during the repair.
Which DS Automobiles DS 4 generations are there?
The DS Automobiles DS 4 is listed as series II. This series has been built since 2021, and production is still running.
The series is listed below with its production period:
- II (since 2021) – current series, still in production
Within a series, control units can differ depending on model year, equipment and market. The assignment should therefore always be checked against the specific unit and the vehicle data before a repair begins.
How do I identify my DS Automobiles DS 4 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 DS 4, it identifies the unit clearly.
The part number is printed on the unit itself and is the most important reference. Note it down before you send the unit in. The vehicle identification number (VIN) and the exact model year of your car help confirm the correct version.
As examples, we cite the fault codes B0091 and B00D5, which are on record for this model. B0091 reports a fault in the left satellite line of the side impact sensor, and B00D5 a fault in the warning light for deactivating the front passenger airbag. A single fault code alone does not prove a defect in the control unit; only testing shows the cause.
What airbag equipment does the DS Automobiles DS 4 have?
The DS Automobiles DS 4 usually has front airbags for driver and front passenger, front side airbags and curtain airbags. Which airbags are actually fitted in a particular vehicle depends on the market and equipment line.
Front airbags protect driver and front passenger in frontal impacts. Side airbags in the front seats deploy in side impacts, and curtain airbags cover the window line to protect the head. The airbag control unit coordinates these systems and triggers them in a crash.
The route to repair is straightforward. Have the fault memory read, the battery disconnected and the control unit removed at a specialist workshop. Then 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 intact and is ready for use as soon as it is refitted — no coding or programming is needed.
