Frequently Asked Questions

What is the first thing to check when the check engine light comes on?

• Check for obvious issues first: a loose or missing gas cap can trigger a code; inspect the fuel cap and tighten it if needed.
• Look for recent symptoms: stalls, rough idle, or loss of power suggest a more urgent fault that needs immediate diagnostics.
• At Land Rover Sudbury we recommend a quick scan with OEM-grade tools to identify stored codes—this fast step prevents unnecessary parts replacement and protects warranties.
• If a repair is covered under warranty it must be performed at a certified dealership to preserve coverage and ensure genuine parts and calibration.

How long does a check engine light service take?

• Most diagnostics take 30–60 minutes for an initial scan and code review; some issues require additional testing or road evaluation.
• Repairs vary: simple fixes like a gas cap or sensor swap can be completed the same day; complex repairs may need parts or calibration and take longer.
• Land Rover Sudbury uses factory procedures to minimize repeat visits—saving you time and money in the short and long term.
• If a repair is covered under warranty, completing work at our certified dealership ensures proper documentation and continued coverage.
