Frequently Asked Questions

What is the first thing to check when the check engine light comes on in a 2015 Land Rover Range Rover?

• Check for obvious issues first: loose or missing gas cap, recent fuel fill with non-recommended fuel (this model requires premium or E85), and visible engine smoke or leaks.
• Note any performance changes: rough idle, stalling, loss of power or unusual noises—these guide priority of repairs.
• Use our fast diagnostic service so a certified technician can read stored trouble codes and recommend the right repair—repairs covered under warranty must be performed at a certified dealership.
• Choosing Land Rover Sudbury often costs less than independent shops by avoiding misdiagnosis and repeat repairs, producing immediate and long-term savings.

How long does a check engine light service take?

• Initial diagnostic scan is typically 30–60 minutes to read codes and perform baseline tests.
• If further inspection or road testing is required, plan for 1–3 hours depending on complexity and parts availability.
• Repairs vary: simple fixes (sensor, gas cap, small vacuum leaks) can be same-day; more involved repairs (catalyst, wiring, fuel system) may take longer.
• We prioritize accurate diagnosis to reduce repeat visits—our factory-trained techs and OEM parts protect warranty coverage and reduce long-term costs.

What does it mean when the check engine light comes on in a 2015 Land Rover Range Rover?

• It indicates the engine management system detected a fault—anything from an emissions sensor to misfire or fuel-system issue.
• Codes may point to oxygen sensors, catalytic converters, misfires, EVAP leaks or fuel trim problems—each has different urgency and cost to repair.
• A flashing light signals an active misfire that can damage the catalytic converter and should be addressed immediately at a certified dealership.
• Using Land Rover Sudbury saves money long-term by ensuring accurate repairs, warranty protection and professional testing that independent shops may not provide.
