Airbag control unit Fiat 500 was broken. Hard to believe but they can really repair it! Recommendation!!
Automatically translated · Original: German
From the first phone call, the order processing, to the shipping, everything was done very quickly and professionally. Now I still have to send the repaired unit to the Swedish workshop and then hopefully the Honda can finally pass the HU there again (failed because of the red airbag light). Thanks to Airbag 24 in Berlin 👍👏. Gerd

What is a BMW iX3 NA5 airbag control unit?
The airbag control unit, also called the SRS control unit, is the central control unit of the restraint system in the BMW iX3 NA5. It evaluates the signals from the crash sensors, decides within milliseconds in an accident whether to fire the airbags and seatbelt pretensioners, and reports faults via the airbag warning light.
This control unit is fitted in the BMW iX3 NA5 (since 2025). While driving, it constantly assesses what the sensors report. If a sensor reports an impact, the unit activates the appropriate restraint devices.
It also stays active during normal operation. When the ignition is switched on, it tests itself and checks the sensors, firing circuits and connected modules. If it detects a fault, it stores it in the fault memory and makes the warning light in the instrument cluster come on.
If it has registered an accident, it stores crash data and locks itself.
Why is the BMW iX3 NA5 airbag control unit defective?
Most often the cause is crash data that remains in the unit after an accident, even if no airbag was deployed. Ageing components, cold solder joints, moisture and corrosion at the connectors, or voltage spikes in the vehicle electrical system may also be the cause.
It usually starts with an accident. The stored crash data stays in the unit even long after the bodywork has been repaired, and an ordinary diagnostic tool cannot remove it. The warning light then stays on.
A second cause is ageing: electronic components lose reliability over the years, and solder joints can develop fine cracks, so that they turn cold and break the contact.
Moisture is another factor. If it reaches the connectors, corrosion forms, which distorts or blocks signals.
Finally, the vehicle electrical system also puts a strain on the electronics. A weak battery or a jump start produces voltage spikes that can damage sensitive components. Typical signs are an airbag warning light that stays on permanently, a fault memory that cannot be cleared, or a diagnostic tool that cannot establish a connection. Which cause applies is only established by testing the unit.
Common error codes for BMW iX3 NA5 airbag control unit repair
The codes that occur in the BMW iX3 NA5 assign the fault to an area of the restraint system: internal faults of the control unit, power supply, stored crash data or a firing circuit.
For your BMW, the following codes are known, each with a short explanation.
- 93D6 → Internal fault detected in the control unit
- 93D7 → Internal fault in the airbag module of the control unit
- 93EC → Internal fault: software or data version faulty
- 93D4 → Crash telegram stored in memory
- 9534 → Power supply: lower limit undershot
- 9535 → Power supply: upper limit exceeded
- 93D1 → Overvoltage detected in the power supply
- 93A8 → Fault in the driver airbag firing circuit, first stage
Error codes are read out with a diagnostic tool. A code alone does not necessarily mean the control unit is defective, as connectors, wiring or an airbag module may equally be to blame. Only testing shows where the fault lies.
What part numbers are available for the BMW iX3 NA5 airbag control unit repair?
On the label of the control unit you will find the part number, which defines its exact version. Depending on equipment and year of manufacture, different numbers are in circulation within a model series.
Once the unit has been removed, read the number from the label and enter it in the repair order. This allows your unit to be matched to the right version. Whether it has a fault is only clarified by reading out the fault memory and by testing.
The route to repair looks like this: have the fault memory read out, then disconnect the battery and remove the control unit. Then create a repair order online and send in the unit. Testing, repairing and checking at Airbag24 usually take 3–4 working days. Your own repaired unit is sent back to you.
The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
