Safety and manufacturer information
HSE explains the additional risks of electric and hybrid vehicle work and the need for appropriate competence and vehicle-specific information. Read the HSE electric and hybrid vehicle guidance.
Manufacturer collision instructions take priority over a generic reset claim. For example, the 2024 and later Tesla Model 3 SRS inspection and replacement instructions specify components to inspect and replace following a collision. That example must not be applied as instructions for another vehicle. Use the current procedure for the exact model and event.

Tell us the vehicle details, current symptoms and repair history. Workshop assessments take place by appointment in Didcot, Oxfordshire. Ask about UK-wide postal assessment only for suitable removed modules and wait for confirmation before dispatch. Do not send batteries, airbags or pretensioners as ordinary module parcels.
