2025 Land Rover Discovery Check Engine Light Reset

Resetting the check engine light on a 2025 Land Rover Discovery should follow a confirmed diagnosis rather than a simple code clear.

At Land Rover Sudbury our technicians perform full system scans, repair or replace defective components with genuine parts, and verify repairs with a final diagnostic test. This approach preserves warranty eligibility, ensures accurate emissions reporting, and delivers immediate savings by eliminating unnecessary repeat visits.
