Frequently Asked Questions

What is the most common reason for check engine light on a 2016 Land Rover LR4?

  • Common causes include engine misfires (codes like P0300), catalytic converter efficiency (P0420), and fuel/air trim issues (P0171).
  • Evaporative system leaks (P0455) from a loose or damaged gas cap are also frequent and simple to fix.
  • Many causes are minor, but untreated issues can escalate to expensive repairs such as catalytic converter replacement.
  • Bring your vehicle to Land Rover Sudbury for an accurate diagnosis — factory-trained technicians ensure fixes protect warranty coverage.

What does it mean when the check engine light comes on in a 2016 Land Rover LR4?

  • The light signals your vehicle’s onboard diagnostics detected a fault in emissions, ignition, fuel, or intake systems.
  • Codes range from simple (loose gas cap) to serious (engine misfire or catalytic damage) — only a scan can identify the code.
  • Early diagnosis at Land Rover Sudbury often lowers repair costs and preserves long-term engine health and resale value.
  • If the code is covered by warranty, certified repairs must be performed at a certified dealership to maintain coverage.

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

  • Start with quick checks: tighten the gas cap, confirm oil level, and note any symptoms like rough idle or loss of power.
  • If the light is steady and the vehicle runs normally, schedule a diagnostic; do not clear codes without diagnosing the cause.
  • If the light is flashing, stop driving and have the vehicle inspected immediately to avoid engine or catalytic converter damage.

2016 Land Rover LR4 Check Engine Light Flashing

The check engine light flashing on a 2016 Land Rover LR4 is a sign of a severe issue, most often an active engine misfire that risks catalytic converter damage and accelerated wear. A flashing light typically indicates unburned fuel entering the exhaust — this can overheat and destroy the catalytic converter, an expensive repair. Do not continue driving; have the vehicle towed or brought in immediately to prevent further harm. At Land Rover Sudbury, our factory-trained technicians prioritize flashing-light cases to limit repair scope and cost. If covered by warranty, remember repairs must be done at a certified dealership to preserve protection. Schedule now for prompt attention.
