What does it mean when the check engine light comes on in a 2025 Land Rover Defender?

• The light is a general alert from the onboard diagnostics system indicating an emissions, engine performance, or sensor issue — it does not always mean catastrophic failure.
• Common triggers include loose fuel caps, oxygen or mass‑airflow sensors, ignition misfires, fuel-trim problems, or evaporative emissions leaks.
• Immediate scanning with an OBD-II tool at our service center identifies the trouble codes so technicians can recommend targeted repairs and prevent larger costs later.
• When covered by warranty, repairs must be done at a certified dealership to protect coverage and vehicle resale value; our team will document and perform required work correctly.

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

• Start simple: check that the fuel cap is fully tightened. A loose cap is a frequent, low-cost cause of the light.
• Inspect for obvious issues — unusual noises, smoke, strong fuel smell, or low oil — and avoid driving if the vehicle shows severe symptoms.
• Note any performance changes (stumble, rough idle, loss of power) and record recent fueling or maintenance; this information speeds diagnosis at our service center.
• For warranties and complex failures, bring the vehicle to Land Rover Sudbury so factory-trained technicians can run the correct diagnostics and maintain any applicable coverage.

What is the most common reason for check engine light on a 2025 Land Rover Defender?

• The most frequent causes are emissions-related sensors and engine misfires — oxygen sensors, MAF sensors, and ignition coils often trigger codes.
• EVAP system leaks (loose gas cap or fuel-system components) and fuel trim issues are also common and typically inexpensive to diagnose and fix when addressed promptly.
• If left unresolved, these issues can lead to reduced fuel economy, failed emissions tests, and more expensive repairs later.
• Land Rover Sudbury’s factory-trained technicians provide precise diagnostics and genuine parts to minimize repeat work and long-term cost.

How long does a check engine light service take?

• A basic diagnostic scan and initial inspection typically take 30–60 minutes; most simple fixes can be completed the same day.
• Complex issues requiring parts, in-depth testing, or drive-cycle verification can extend total shop time to several hours or multiple visits.
• Because we stock many genuine parts and have factory-trained technicians on site, turnaround is often faster and more reliable than independent shops, producing immediate and long-term savings.
• To protect warranty coverage, any warranty repairs must be performed at a certified dealership; schedule service online to secure a convenient appointment.
