Airbag control unit with part number BMW-Nr.:319296494010

What is the function of the airbag control unit BMW part no.: 319296494010?

The airbag control unit with part number BMW no.: 319296494010, also known internally as 0285011730, is the central safety module in the BMW 1 Series F20. It is responsible for monitoring the crash sensors and, in the event of an accident, controls the deployment of airbags, seatbelt pretensioners, and the active pedestrian protection system.

This module acts as the brain of the passive safety system (SRS - Supplemental Restraint System). It continuously receives and processes data from acceleration and pressure sensors distributed throughout the vehicle to analyze the driving situation.

Based on this data, the control unit decides within milliseconds whether a collision has occurred and which restraint systems need to be activated to provide optimal protection for the occupants. The proper functioning of this safety-critical component is therefore vital for vehicle safety.

Why does the control unit BMW no.: 319296494010 fail?

The most common cause of failure for control unit 319296494010 is the storage of crash data after an accident. This data irreversibly locks the module and triggers the airbag warning light. Other causes may include internal electronic faults, such as insufficient supply voltage (error code 0000F0), or issues with external wiring.

Following a collision—even minor ones—a data record is stored in the control unit’s memory. These “crash data” serve to document the accident but simultaneously disable the module to prevent erroneous activation after the incident. Deleting this data is not possible using standard workshop diagnostic tools.

In addition to this primary cause, internal components on the circuit board can also fail. Before diagnosing the control unit as the root cause, a qualified workshop should always inspect the peripherals—cables and connectors—for damage, since the source of the problem does not always lie within the module itself.

How do you recognize a defect in BMW no.: 319296494010?

A defective airbag control unit 319296494010 primarily manifests as a permanently illuminated airbag warning light on the instrument cluster. Often, the fault memory cannot be cleared, or communication between the diagnostic tool and the control unit has been lost. Error messages such as “Airbag malfunction” are also typical.

The most noticeable sign is the red airbag warning lamp that fails to turn off after starting the engine. This indicates a serious fault in the safety system that requires immediate inspection.

If a workshop attempts to read the fault memory, it often fails because the control unit no longer responds to requests via the OBD-II interface. In some cases, specific warnings appear on the vehicle display, pointing to a defect in the restraint system or the fuel shut-off valve.

Even if no major accident occurred, the storage of crash data in the engine control unit can be another indication that the SRS module needs to be checked.

In which models is BMW no.: 319296494010 installed?

The airbag control unit with part number BMW no.: 319296494010 is primarily installed in the BMW 1 Series F20 five-door model, manufactured between 2011 and 2019. At Airbag24, we repair this specific module for models such as the BMW 116d and other variants of this series. Similar control units can also be found in the F21 and F30 models.

At Airbag24, we specialize in repairing this control unit for the following vehicle series:

BMW 1 Series F20 five-door (model years 2011–2019)

Although technically closely related to modules from adjacent series, such as the BMW 1 Series F21 (three-door) or the BMW 3 Series F30, an exact match of the part number—319296494010—is crucial for compatibility. Related numbers like 929649401 or 6867168 may also refer to this or a compatible device.

How does the repair process work at Airbag24?

In the professional repair of control unit 319296494010, the stored crash data is first erased through a specialized reset procedure. Subsequently, all internal electronic components are inspected and repaired as needed. After successful testing, the unit is returned with a 12-month warranty.

Upon submission to Airbag24, the repair follows a proven, multi-step process. First, an initial inspection verifies the reported fault. The core of the repair involves erasing the vehicle-specific crash data from the internal memory, which in most cases restores full functionality.

If additional internal faults are detected—such as issues with voltage regulators or memory chips—these are expertly rectified. The goal is a “plug-and-play” solution; however, in some vehicle configurations, re-coding with BMW-specific software (ISTA) may be required after installation, which should be verified by a qualified workshop.

Before being returned, each unit undergoes a final functional test to ensure flawless operation. We provide a 12-month warranty on every repair.
