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 a Volkswagen Golf R Mk7 airbag control unit?
The Volkswagen Golf R Mk7 airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It monitors sensors, stores crash data, and ensures the proper functioning of all airbag modules in the vehicle to provide maximum protection and minimize system failures.
This electronic control unit (ECU) is responsible for processing sensor information. In the event of a collision, it triggers the precise and timed deployment of the airbags to protect the occupants.
The system continuously analyzes data from various crash sensors that measure acceleration and pressure. This enables fast and reliable accident detection and the storage of relevant data for later diagnostics.
It has communication interfaces for vehicle diagnostics and fault memory retrieval, typically via VAG communication protocols. After an accident, the control unit stores crash data, which must be erased after repairs.
Why is the Volkswagen Golf R Mk7 airbag control unit defective?
A Volkswagen Golf R Mk7 airbag control unit commonly fails due to internal memory corruption or communication errors, often triggered by an accident or power surges. This can result in a persistent airbag fault light and impair the system's safety function, necessitating repair or replacement.
The most common cause is error code B2000 00, which indicates an internal memory integrity malfunction of the airbag control unit. This checksum error often represents a total failure that can only be remedied by replacing the module or performing a specialized repair.
Other causes include communication problems in the CAN bus, which appear as error codes such as B1000, U1121 00, or U1123 00. These indicate missing or invalid messages in the system that disrupt the airbag control unit's data exchange.
Even after an accident, the control unit stores crash data, which causes it to become blocked and require resetting. Without a reset, the Volkswagen Golf R Mk7 airbag control unit cannot be put back into operation.
Common error codes for Volkswagen Golf R Mk7 airbag control unit repair
When repairing a Volkswagen Golf R Mk7 airbag control unit, specific trouble codes identify the exact cause of the malfunction, from internal memory errors to communication problems in the vehicle's network. These codes are crucial for precise diagnosis and effective resolution of the problem.
- B2000 00 → Internal control unit memory check faulty → The memory integrity of the airbag control unit is impaired (checksum error).
- B1000 → Control unit communication error → Problems in the data exchange between the airbag ECU and other control units in the vehicle.
- U1121 00 → Missing message (CAN bus) → An expected message from the airbag control unit is missing in the CAN bus.
- U1123 00 → Error message received (CAN bus) → The airbag control unit has received an invalid or faulty message on the CAN bus.
What part numbers are available for the Volkswagen Golf R Mk7 airbag control unit repair?
For the Volkswagen Golf R Mk7 airbag control unit repair, the only 100% verified OEM part number is 5Q0 959 655 C, which is listed by Volkswagen itself as a Bosch OEM part. This number is precisely matched to the series and has been confirmed by professional repair services.
The primary verified part number for the airbag control unit (SRS) in the Golf 7 Type AU (Mk7), including the Golf R, is 5Q0 959 655 C. It is listed in official VW spare parts catalogs and repair services.
This number is also used by Bosch as an original equipment manufacturer (OEM), as Bosch is a major supplier of such control units to Volkswagen. Other designations such as 5Q0 959 655 AA/AT are often compatible variants of the same basic model.
It is important to note that other frequently mentioned part numbers such as 1K6 880 742 P or 5H0 880 204 H refer to airbag cushions or other airbag modules, not the central airbag control unit itself.
