Airbag control unit with part number A2C96376516

What is the function of the airbag control unit A2C96376516?

The airbag control unit A2C96376516 is the central control module for the occupant protection system (SRS) in Audi Q5 FY models. It processes signals from crash sensors to precisely deploy airbags and pretensioners in the event of a collision. Proper functionality is critical for passive vehicle safety.

As an SRS ECU (Supplemental Restraint System Electronic Control Unit), it continuously monitors all safety‑related components, including front, side, and head airbags, seatbelt pretensioners, as well as their associated acceleration and pressure sensors. The control unit ensures that the system remains operational at all times and provides optimal protection to occupants during a crash.

Why does the airbag control unit A2C96376516 fail?

The most common cause of failure for the A2C96376516 control unit is the storage of crash data after a collision. This data permanently locks the unit, disabling the entire airbag system. In addition, spontaneous internal electronic faults on the circuit board can occur even without any accident.

Following a crash—even one with low impact energy—the control unit stores an irreversible data record. This “crash‑lock” feature is a manufacturer‑imposed safety measure that requires a system check. Without professional repair and deletion of this data, the system remains non‑functional.

Spontaneous malfunctions without any prior accident are also known. These are purely electronic issues, such as capacitor failures or other component defects on the circuit board, which can lead to complete system failure. Similar fault patterns appear in the compatible variants 80A959655N, 80A959655G, 80A 959 655 N, and 80A959655AE.

How do you recognize a defect in the A2C96376516 control unit?

A defect in the A2C96376516 control unit is unmistakably indicated by the persistent illumination or flashing of the SRS warning light (airbag indicator) in the instrument cluster. This is a critical signal, as the entire occupant protection system is disabled in this state and will not deploy in the event of a crash.

The illuminated warning light directly informs the driver that there is a fault in the restraint system. While continuing to drive may be technically possible, it poses a significantly increased safety risk to all occupants. Immediate inspection at a qualified workshop is therefore essential.

In some cases, additional error messages may appear on the display, pointing to a problem within the airbag system. The exact cause—such as “control unit defective” or “crash data stored”—can then be diagnosed using a diagnostic tool.

In which vehicles is the A2C96376516 control unit installed?

The airbag control unit A2C96376516, along with its compatible variants, is specifically installed in second‑generation Audi Q5 models (FY type). This includes both the original version and the facelift model, allowing for clear identification.

At Airbag24, we repair this control unit for the following specific models:

Audi Q5 (FY type) – model years 2017 to 2020

Audi Q5 Facelift (FY type) – model years 2020 to 2024

The repair method is identical for all listed variants, such as 80A959655N and 80A959655G, since they share the same hardware platform and exhibit the same fault patterns.

How is the A2C96376516 control unit professionally repaired?

Professional repair of the A2C96376516 restores full functionality without requiring an expensive new part or reprogramming. The process involves precise diagnostics, secure deletion of crash data, and replacement of faulty electronic components on the circuit board.

After submission to Airbag24, each control unit undergoes a standardized repair procedure. First, a systematic analysis identifies the exact cause of the fault—whether it’s a locked memory due to crash data or a hardware issue affecting sensors or circuit board components.

Next, the stored crash data is securely and completely erased. If the diagnosis reveals a hardware defect, the faulty components are expertly replaced, restoring the original functionality as if the unit were brand new.

Before returning the repaired unit, each device undergoes a comprehensive functional test to ensure flawless operation of all system components. We provide a 12‑month warranty on all repairs.
