Frequently Asked Questions

What is the most common reason for check engine light on a 2015 Land Rover LR4?

• Common causes include a loose or faulty gas cap, oxygen sensor failure, EVAP system leaks, ignition misfires, and catalytic converter issues.
• Many issues start small (e.g., a gas cap or O2 sensor) but left unchecked can lead to expensive repairs like catalytic converter replacement.

• Repairs covered under warranty must be completed at a certified dealership to protect coverage and ensure long-term savings.

What does it mean when the check engine light comes on in a 2015 Land Rover LR4?

• The light is a general alert that the vehicle’s onboard diagnostics have logged a fault code; severity ranges from minor emissions issues to engine misfires requiring immediate attention.
• An illuminated steady light indicates a fault that should be diagnosed soon; a flashing light signals a serious condition that can damage components like the catalytic converter.
• At Land Rover Sudbury we use factory-grade scanners to read and interpret codes accurately, avoiding unnecessary work and delivering immediate and long-term savings compared with many independents.
• Any warranty repairs must be performed at a certified dealership to maintain coverage and manufacturer-grade repairs.

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

• Start with simple checks: ensure the gas cap is tight and undamaged; a loose cap is a common trigger for an EVAP code.
• Look for obvious signs — low oil, coolant leaks, or unusual noises — but avoid DIY resets before diagnosing the root cause.
• If the light is flashing, stop driving and contact Land Rover Sudbury immediately; we recommend avoiding continued operation until a certified diagnosis is completed.
• Scheduling service with our factory-trained technicians preserves warranty eligibility and often reduces long-term repair costs.
