Frequently Asked Questions

What is the most common reason for check engine light on a 2021 Land Rover Range Rover Sport?

• Loose or faulty gas cap — the simplest and most frequent cause; quick to fix and often clears the light after a few drive cycles.
• Faulty oxygen sensor or catalytic converter issues — can affect fuel economy and emissions if left unaddressed.
• Ignition coil or spark plug problems — may cause misfires, rough running, and potential long-term engine damage.
• Turbo/twincharger or intake issues — performance models use advanced induction; when these systems falter, costs rise if not repaired.
• Bring your vehicle to Land Rover Sudbury so our factory-trained team can diagnose correctly and help avoid costly future repairs.
