2021 Land Rover Range Rover Check Engine Light Flashing

A flashing check engine light signals a severe condition—often an active misfire that can spray unburned fuel into the exhaust and rapidly damage the catalytic converter. Immediate dealer attention is important because continued driving may escalate costs from a sensor swap to full exhaust or engine repairs. At Land Rover Sudbury, our technicians prioritize flashing-light diagnostics, using OEM tools to identify ignition, fuel, or sensor failures and to prevent collateral damage. While independent shops can perform repairs, our factory-trained team often costs less overall by delivering accurate fixes the first time, preserving warranties, and avoiding repeated labor charges over time.

2021 Land Rover Range Rover Check Engine Light Reset

Resetting the check engine light without resolving the underlying fault can mask recurring issues and lead to larger repairs later. Dealers can clear codes after repairs and run drive-cycle verification to ensure the fault does not return. Land Rover Sudbury recommends full diagnostics and repair because warranty-covered repairs must be performed at a certified dealership; this protects your coverage and ensures OEM parts and calibrated software updates. Choosing dealer service offers immediate savings through correct diagnosis and long-term savings by preventing repeated visits. Use our online service scheduler to book a diagnostic and get a clear repair plan with transparent pricing.

2021 Land Rover Range Rover Check Engine Light Codes

Common codes include misfire codes (P0300 series), oxygen sensor or catalyst efficiency (P0420), EVAP leaks (P0455), and fuel trim or MAF sensor codes (P0171/P0101). Left unaddressed, misfires can destroy a catalytic converter—replacement costs often range into the thousands—while simple sensors typically cost a few hundred dollars to replace. Regular dealer diagnostics catch issues early, lowering total ownership costs. At Land Rover Sudbury we supply transparent estimates and factory-supported repairs; performing covered work at a certified dealership preserves warranty benefits and prevents out-of-pocket expenses caused by deferred maintenance or incorrect repairs.
