2012 Land Rover LR2 Check Engine Light Flashing

A flashing check engine light usually signals a severe condition — often an active misfire that can damage the catalytic converter, overheat components, or cause sudden loss of power. If your 2012 Land Rover LR2 shows a flashing light, stop driving as soon as it is safe and have the vehicle towed to Land Rover Sudbury; continued operation risks much higher repair costs. Our service team will run a full diagnostic scan, inspect ignition, fuel, and emission systems, and provide a transparent estimate. Because warranty-covered repairs must be completed at a certified dealership, bringing your vehicle to us protects coverage and delivers immediate and long-term savings.

2012 Land Rover LR2 Check Engine Light Reset

Resetting the check engine light without resolving the root cause only masks the symptom. For a proper reset, our technicians first read and clear diagnostic trouble codes, verify repairs, and run drive-cycle tests to ensure the issue is resolved. At Land Rover Sudbury we use factory-level tools and genuine parts, which reduces repeat visits and preserves vehicle value. Performing diagnostics and repairs at our dealership often costs less overall than repeated independent fixes, thanks to accurate troubleshooting and warranty protections. Schedule certified service online to keep warranty coverage intact and benefit from our factory-trained team's long-term savings approach: Schedule Service.

2012 Land Rover LR2 Check Engine Light Codes

Common codes on a 2012 Land Rover LR2 include P0420 (catalyst efficiency), P0300 (random/multiple misfires), P0171/P0174 (lean fuel trim), P0455 (EVAP large leak), and P0130–P0167 (oxygen sensor or circuit faults). Ignoring these codes can escalate costs: an oxygen sensor replacement is moderate, while untreated misfires or a failing catalytic converter can cost over $1,000. EVAP leaks are often inexpensive to repair but affect emissions testing and fuel economy if left. Quick, accurate diagnosis at Land Rover Sudbury reduces long-term expense; warranty-covered repairs must be handled by a certified dealer to ensure genuine parts and continued coverage.
