Ok.
Airbag24 is a very well organized company. The shipping procedure is correct and reliable. The quick repair right after receipt, the clear payment after repair, the UPS shipping right away. I am very satisfied with the repair of my airbag control unit on Ducato 250 2.3 130 hp year 2018. The reassembly is easy. The airbag light went off after reconnecting the battery and everything went back to how it was before. Very good service!

What is an Audi A6 C6 4F airbag control unit?
The Audi A6 C6 (Type 4F) airbag control unit is the central safety unit in the vehicle, responsible for monitoring and deploying all occupant restraint systems. It records accident data, calculates deployment decisions, and activates airbags and seatbelt pretensioners as needed to ensure occupant safety.
This electronic module is crucial for the airbag system in the Audi A6 C6 (model years 2004 to 2011). It processes signals from crash sensors and ensures correct function in an emergency. Precise diagnosis in the event of problems is essential for operational safety.
Why is the Audi A6 C6 airbag control unit defective?
An Audi A6 C6 airbag control unit is often reported as "defective" after an accident because it stores crash data and locks up. Internal software errors or electronic failures can also render the control unit unusable, so a professional Audi A6 C6 airbag control unit repair is often unavoidable.
Because crash data is permanently stored in memory after an impact, the control unit cannot be restarted without professional erasure. A failure can also be indicated by a permanently illuminated airbag warning light. Such malfunctions require specialized diagnosis and repair to restore the safety system's full functionality.
Common error codes for Audi A6 C6 airbag control unit repair
Specific error codes such as B1000 or 65535 directly indicate a defect or communication problem with the airbag control unit in the Audi A6 C6. These codes indicate the need for a specialized Audi A6 C6 airbag control unit repair to restore the safety system to full functionality.
- B1000 → Control unit communication error → No communication with the diagnostic device, indicates an internal defect or a problem with the power supply of the control unit.
- 65535 → Control unit defective / software error → A general internal error that often requires repair of the control unit.
- U1101 → Communication error (component protection) → Occurs after replacing the control unit because the VAG component protection was not activated correctly.
- U1100 → Communication error (component protection) → Similar to U1101, typically occurs after replacement with a new control unit, which then requires coding or activation.
What part numbers are available for the Audi A6 C6 airbag control unit repair?
There are several verified OEM part numbers for the Audi A6 C6 (4F) airbag control unit, which may vary depending on the year and equipment. These numbers are crucial for identifying the correct replacement part and ensuring the correct Audi A6 C6 airbag control unit repair or replacement.
Common original part numbers include 4F0 959 655 B and 4F0959655B, which are suitable for many models. For facelift variants from 2008 onwards, part number 4F0959655G is often relevant. The number 4F0910655E serves as the official replacement number for the same control unit, while 4F0959655 is a frequently used shortened version. These numbers are specifically valid for Audi A6 C6 (model 4F, built between 2004 and 2011) airbag control units and must be verified for successful diagnosis or repair.
