Airbag module reset and SRS assessment

Assess the complete restraint-system repair

AXION Automotive reviews SRS control-module enquiries to establish whether the requested bench work is suitable. Send the part number, diagnostic fault codes and details of the incident or existing fault before removing or posting the module.

Module work is only one part of a restraint-system repair. Airbags, seat-belt pretensioners, sensors, wiring and other affected components require appropriate inspection and repair under the vehicle manufacturer’s procedures. Some modules require replacement.

What to send with your enquiry

• Vehicle registration, make, model and year.
• A clear photograph of the SRS module label and full part number.
• The complete diagnostic scan report and exact fault codes.
• Whether the vehicle was involved in an impact and which restraints deployed.
• Details of repairs, replacements and previous module work.
• Your installer’s findings and the proposed next step.

Supported module work

Suitability depends on the module and fault. The assessment may concern stored crash information, module communication or an internal electronic fault. We discuss the available route rather than assuming every unit can be reset.

Do not send airbags, pretensioners or other pyrotechnic components with a control-module enquiry. Confirm the exact item and delivery instructions first.

Recent BMW 4 Series module data work

Our workshop work on 18 October 2026 included crash-data reset work for a 2021 BMW 4 Series SRS module, involving a data read, modification and write-back. This records the module work carried out; it does not certify the vehicle’s complete restraint system.

Read the BMW SRS workshop note. The suitability of work on another module must be checked against its identity, condition and the vehicle manufacturer’s repair requirements.

Booking and assessment costs

Send the module details before booking or posting it. We confirm the assessment charge, supported work and expected next steps first. You can review assessment services and appointments; use the postal repair guide once the item and job have been agreed. Tell us which garage will complete the vehicle-side repair and final checks.

SRS repair questions

Will a reset repair deployed airbags?

No. A module reset does not repair or replace deployed or damaged restraint components. The complete system must be dealt with by an appropriate repairer.

Is an extinguished warning light proof of a complete repair?

No. The installer must complete the required diagnosis, repair and checks. A bench service does not certify the vehicle’s complete restraint system.

What does an SRS warning mean for an MOT?

The DVSA inspection manual classifies an SRS malfunction indicator showing a system fault as a major defect. A passenger-airbag-disabled indicator is different.

Can I send the module from anywhere in the UK?

Where the identified job is suitable and agreed, we can discuss postal assessment. Keep the diagnostic report and job details with the module.

What if replacement is needed?

Confirm the correct replacement and any coding requirements with the installer. Do not purchase a donor solely because its casing looks the same.
