What is the most common reason for check engine light on a 2014 Land Rover LR4?

• Common causes include misfires (ignition or fuel), failing oxygen sensors, and catalytic converter efficiency problems.
• Evaporative emissions leaks (loose gas cap or cracked hose) frequently trigger codes that are easy to repair.
• Left unaddressed, sensor or exhaust issues can raise long-term costs through reduced MPG and component damage.
• At Land Rover Sudbury we diagnose quickly with factory tools to often reduce immediate and long-term repair costs compared with independent shops.
• Repairs covered under warranty must be completed at a certified dealership to preserve coverage and ensure proper repair.

What does it mean when the check engine light comes on in a 2014 Land Rover LR4?

• It signals the powertrain control module detected a fault — anything from a loose gas cap to a serious engine or emissions issue.
• Codes need reading with an OBD-II scanner to identify severity and required repair steps.
• Some faults are minor; others can harm fuel economy, emissions systems, or engine components if ignored.

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

• Schedule service with Land Rover Sudbury so factory-trained technicians use manufacturer procedures and protect any applicable warranty.

How long does a check engine light service take?

• Simple diagnostics and minor repairs can often be completed the same day — typical scans take 30–60 minutes.

• Land Rover Sudbury provides clear time estimates after diagnosis and uses parts on hand when possible to reduce downtime.
• Choosing our dealership frequently reduces time and cost versus repeating repairs at independent shops, and warranty work must be done at a certified dealer for coverage.
