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 ID.4 E2 airbag control unit?
The Volkswagen ID.4 E2 airbag control unit is the central safety unit in your all-electric VW ID.4 (model years 2021-2022). It continuously monitors vehicle sensors, stores relevant crash data, and precisely activates all occupant restraint systems such as airbags and seatbelt pretensioners in the event of an accident to ensure maximum occupant protection.
This microprocessor-based control unit is crucial for controlling the ID.4's passive safety systems. It works seamlessly with the vehicle's electrical system and high-voltage architecture.
The airbag control unit processes incoming data from acceleration and pressure sensors. It makes a decision in milliseconds as to which restraint systems should be deployed in the event of an impact.
Why is a Volkswagen ID.4 E2 airbag control unit repair necessary?
A Volkswagen ID.4 E2 airbag control unit repair is often necessary because the module has stored crash data after an accident that prevents it from functioning again, or because internal electronic defects, communication problems, or incorrect voltage supply can occur, which impair operational readiness.
Common causes of a defect include internal malfunctions of the control unit itself or damage caused by overvoltage. An incorrect software or hardware version can also cause problems.
After an accident, the airbag control unit usually needs to be reset, as it stores crash data as a permanent error. This is the only way to restore the safety system's functionality.
A control unit failure is usually indicated by the illuminated airbag warning light in the instrument cluster. This is a clear sign that a diagnosis and possible Volkswagen ID.4 E2 airbag control unit repair is required.
Common error codes for Volkswagen ID.4 E2 airbag control unit repairs
When repairing the Volkswagen ID.4 E2 airbag control unit, certain error codes indicate problems with the airbag control unit itself, not with sensors or other components. These B-codes indicate internal errors, communication malfunctions, or stored crash data that require repair.
- B1000 → Control unit communication error → Communication between the airbag control unit and other modules is disrupted.
- B1001 → Internal error in the control unit → Defect within the airbag ECU hardware or software.
- B1010 → Supply voltage out of range → Voltage at the airbag control unit too high or too low.
- B1011 → Reset/function call impossible → Control unit cannot be reset or execute commands.
- B1012 → Memory error (EPROM/Flash) → Damage to the internal memory in the airbag control unit.
- B1013 → Configuration error → Incorrect or missing configuration data in the control unit.
- B1014 → Incorrect software version → Incompatible or corrupted software on the airbag control unit.
- B1015 → Incorrect hardware version → The installed hardware version of the control unit is incorrect.
- B1020 → Crash data stored in the control unit → After an accident, crash data was permanently stored in the control unit, which makes a Volkswagen ID.4 E2 airbag control unit repair by reset necessary.

For the Volkswagen ID.4 E2 airbag control unit repair, the exact, original OEM part number 1EA959655EA from Volkswagen is the only officially verified and relevant number.
