What is a Volkswagen e-Golf BE1 airbag control unit?
The Volkswagen e-Golf BE1 airbag control unit is the central safety unit in the vehicle, precisely activating all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors sensors, stores relevant crash data, and ensures the flawless functioning of the entire safety system, essential for occupant safety.
This control unit acts as a control center, processing signals from impact sensors. It then triggers the appropriate protective mechanisms within milliseconds as needed.
Why is the Volkswagen e-Golf BE1 airbag control unit defective?
A Volkswagen e-Golf BE1 airbag control unit is often defective because it stores crash data after an accident, preventing further use, or because internal components fail. These defects, often indicated by error codes B2000 or B200000, require professional repair or replacement of the module to restore full functionality of the safety system.
The most common cause of a defect is the storage of crash data after an accident, which results in the system being deactivated. Without deleting this data, the control unit will no longer function properly.
Another reason for failure could be internal component damage that disrupts signal processing. This causes the control unit to report malfunctions or the airbags to not deploy properly.
Common error codes for Volkswagen e-Golf BE1 airbag control unit repair
During a Volkswagen e-Golf BE1 airbag control unit repair, specific error codes occur that directly indicate a fault in the control unit. These codes are crucial for a precise diagnosis and indicate that the module itself is malfunctioning or that crash data repair is necessary to restore system safety.
- B2000 → Control unit defective → General malfunction or internal defect of the airbag control unit.
- B200000 → Control unit: Component defective → Specific error of an internal component of the airbag control unit.

For the Volkswagen e-Golf BE1 airbag control unit repair, only the original OEM part numbers 5Q0 959 655 AA and 5Q0 953 549 E are verified as 100% compatible. These numbers guarantee correct function and software compatibility for your vehicle model, as airbag control units are programmed specifically for each vehicle and cannot simply be replaced with other versions.
The part number 5Q0 959 655 AA is an original part number used by Volkswagen, directly related to the e-Golf BE1 (Golf 7 Type AU). It has been confirmed multiple times and is only suitable for this vehicle type.
Another original OEM part number is 5Q0 953 549 E, which has also been validated for the Volkswagen e-Golf BE1 model year 2018 (Golf 7 platform). These two numbers ensure the required compatibility and safety.
Older numbers such as 1C0 909 605 A or 6Q0 909 605 A do not fit the e-Golf BE1. Similar Golf 7 variants such as 5Q0959655M are also not suitable for the specific BE1 model without further testing and should be avoided to prevent malfunctions.
