If your 2012-2020 Dacia Sandero’s instrument cluster is displaying a permanent airbag warning light and diagnostics cannot communicate with the airbag module, this strongly indicates an internal failure within the airbag ECU that will require repairing.

The airbag control module fitted to the Dacia Sandero is a Continental-manufactured ECU which is also found on the Dacia Duster and certain Renault models, including the fourth-generation Clio.

As with the other models, when the airbag ECU fitted to the Dacia Sandero develops a fault, the entire supplemental restraint system is disabled, and crucial safety features will remain unavailable until the control module is repaired. This results in the airbag and safety-belt pretensioners being unable to deploy in the event of a collision.

Dacia Sandero Airbag ECU Fault – Causing Airbag Light

In the second-generation Dacia Sandero, the airbag ECU is mounted under the centre console and serves as the core decision-maker for the supplemental restraint system. This control module monitors inputs from two crash sensors, located behind the B-pillars, to decide whether the conditions of a collision meet the deployment thresholds. Once these criteria are met, the control module sends a signal to the inflator system, deploying the appropriate front or side airbags and safety-belt pretensioners. 

Under normal operation, the airbag control module in your Sandero communicates continuously over the vehicle’s high-speed CAN bus, to share system status and diagnostic information with other control modules. When this communication is lost or interrupted, however, the airbag warning light illuminates on the Dacia Sandero’s instrument cluster to indicate that there is a fault within the system.

In this condition, the SRS will be unavailable, and the airbags and safety-belt pretensioners will not deploy correctly in a collision. These symptoms, along with the aforementioned airbag warning light will persist until the fault in your Dacia Sandero’s airbag ECU is repaired.

Repair or Replace Your Dacia Sandero Airbag ECU?

If you are experiencing these symptoms, or your OBD scanner is showing a timeout message when trying to communicate with the module, you may have been advised to replace rather than repair the airbag ECU fitted to your Dacia Sandero, in order to resolve the warning light and restore diagnostic communication. 

This is not a reliable solution, as replacement units contain the same design flaw and components that caused the original fault, leaving you vulnerable to a repeat malfunction. Instead, we recommend a comprehensive rebuild of your Sandero’s airbag control module.
