Where it lives: Usually in the centre tunnel near the gear selector; on vans, under the dashboard or seats.

How it works

  1. Order online. Pay securely by card, Apple Pay, Google Pay or Klarna. You get a reference straight away.
  2. Post the module to us (or drop it in). Wrap it well and put a note in the box with your reference. We recommend a tracked service.
  3. Same-day reset. We remove the crash data, clear the codes and bench-test the module on the day it arrives.
  4. Back to you. Posted back free by Royal Mail Tracked 48, or upgrade to Special Delivery. Refit it, and the airbag light goes out.

Good to know

Reset, not replaced

Your original module goes back in, so there is no coding to the car, no new-part cost and no VIN mismatch.

Healthy modules only

The price is for clearing crash data from a working unit. If yours turns out to have an internal fault or won’t communicate, we contact you before doing anything else.

Bodyshops & garages

Send us the module mid-repair and it’s back before the car is. Call 01792 732 062 for trade volumes.
