Quick answers before you post

Part number: look for the sticker on the airbag ECU. Note every line, including suffix letters. If the print is worn, WhatsApp a clear photo.

Crash data reset: we receive your module, clear stored crash data, test it, and send it back. For most modules, if we receive it in the morning, we complete the crash data reset and send it back the same day.

Useful official references

For MOT rules on warning lights, use the official DVSA guidance rather than forum guesswork. An illuminated airbag or SRS lamp is treated as a restraint-system fail until the fault is fixed.
