Frequently Asked Questions

What is the most common reason for check engine light on a 2018 Land Rover Range Rover?

• Most often it’s an emissions or fuel-delivery issue: faulty oxygen sensors, a failing catalytic converter, MAF/airflow sensors, or fuel trim problems.
• These failures can arise from using non-recommended fuel, ignition misfires, or sensor wear over time on a supercharged V8 platform.
• Left unchecked, an emissions problem can increase fuel use, reduce performance, and lead to expensive converter or engine repairs.
• At Park Place Land Rover in Dallas, TX, our factory-trained technicians diagnose the root cause to avoid repeat work and save you money long term.
• Remember: any repairs covered under warranty must be performed at a certified dealership to preserve coverage and ensure proper parts and labor.

How long does a check engine light service take?

• Initial scan and code read: typically 15–30 minutes using manufacturer-grade tools to capture live data and freeze-frame information.
• Full diagnosis usually requires 1–3 hours depending on symptoms, road testing, and component testing (sensors, ignition, fuel system).
• Repairs vary: simple sensor replacements can be same-day; more involved repairs (catalytic converter, fuel system) may take longer.
• Our technicians provide an estimated timeline up front — doing the job right the first time delivers immediate and long-term savings versus repeat attempts.
• Warranty repairs must be completed at a certified dealership to maintain coverage and ensure OEM parts and procedures are used.

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

• Start with an OBD-II scan to capture diagnostic trouble codes — this provides the most direct clue to the affected system.
• Check for obvious, simple causes: loose fuel cap, recent fuel type, visible wiring or connector issues, or recent service entries.
• If the light is steady, you can often drive cautiously to a certified service center; if flashing, stop driving and seek immediate service.
• At Park Place Land Rover we use factory diagnostic tools to accurately read codes and live data so repairs are precise and durable.
• Performing warranty-covered repairs at a certified dealership preserves coverage and minimizes long-term ownership costs.

What does it mean when the check engine light comes on in a 2018 Land Rover Range Rover?

• It indicates the vehicle’s onboard diagnostics have detected a fault in emissions, ignition, fuel, or engine management systems.
• Faults range from minor (evap leak, loose cap) to serious (misfires, catalytic overheating) — codes differentiate urgency and cause.
• Because this model is a supercharged V8, timely diagnosis prevents performance loss, poor fuel economy, and potential damage to the catalytic converter.
• Park Place Land Rover provides manufacturer-grade diagnostics and factory-trained technicians to identify and fix the true cause quickly and correctly.
• Warranty-covered issues must be repaired at a certified dealership to protect coverage and ensure genuine parts and correct procedures.
