Works like a charm!
Everything went perfectly, I can only recommend it.

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 light for the airbag). Today the message came from SWE, the car is running again, the red light is off and the HU was also passed. Once again many thanks for the help in need. Keep it up and maybe word will also spread in SWE that Airbag 24 does great work. Regards Gerd

Everything worked out great! Read out fault memory, sent it in, received offer and sent in the defective control unit. Got it back repaired after 3 days, price exactly as in the offer. It can't get any better 👍

What is an Audi A6 C7 airbag control unit?
The Audi A6 C7 airbag control unit is the central safety component of your vehicle, precisely controlling all occupant restraint systems, such as airbags and seat belt pretensioners, in the event of an accident. It continuously processes signals from crash sensors, evaluates them in milliseconds, and ensures the targeted activation of the protection systems for optimal occupant protection.
This module is specifically designed for the Audi A6 C7 series (type 4G, built between 2011 and 2018). It continuously monitors the functionality of all connected airbag and seat belt systems.
The control unit reports errors via the on-board electronics and the airbag warning light and stores relevant crash data for later diagnosis. It is a key component for passive safety and must be repaired if it fails.
Why is the Audi A6 C7 airbag control unit defective?
An Audi A6 C7 airbag control unit may be defective because a crash lock was activated after an accident, preventing reuse without professional repair. Aging, overvoltage, or moisture also frequently cause internal defects. These then lead to malfunctions or the illumination of the airbag warning light, requiring immediate diagnosis.
Often, an impact causes crash data to be stored, which locks the control unit and causes the airbag warning light to remain permanently illuminated. Repair or replacement of the module is then mandatory.
Faulty internal components or corrosion caused by water ingress can also lead to failure. In such cases, a precise diagnosis of the control unit is essential to correct the problem and repair your airbag system.
Common error codes for Audi A6 C7 airbag control unit repair
When repairing the Audi A6 C7 airbag control unit, specific error codes are essential for a precise diagnosis. They directly indicate problems within the airbag ECU or its communication. These codes help identify the exact cause of an illuminated airbag warning light, allowing for targeted repair.
- B1003 11 → Short circuit to ground at igniter 2 (passenger side) → Control unit-specific error, often in US versions or internal problems.
- B100B 11 → Driver side airbag igniter failure → Direct failure in the driver airbag igniter circuit, reported by the airbag ECU.
- B100611 → Rear belt tensioner, driver's side, short circuit to ground → Indirect control unit error due to short circuit in the belt tensioner circuit, registered by the airbag module.
- B200F F0 → Unknown error, possibly control unit compatibility → Indication of communication problems or incompatible connected modules such as steering wheel coil spring.
- 9440017 → Driver side airbag igniter error (manufacturer-specific VAG) → VAG-specific internal error that affects the driver airbag ignition circuit in the control unit.
