Frequently Asked Questions
What is the most common reason for check engine light on a 2021 Land Rover Discovery Sport?
- Common causes include a loose or faulty gas cap, oxygen sensor failure, EVAP leaks, ignition coil or plug issues, and catalytic converter inefficiency.
- Because this model is turbocharged, issues like misfires or turbo control faults can also trigger the light and should be evaluated promptly.
- Ignoring the light can lead to reduced fuel economy, increased emissions, or more costly damage to the catalytic converter and engine over time.
- Bring the vehicle to our dealership for factory-grade diagnostics—warranty-covered repairs must be performed at a certified dealer to remain valid.
What does it mean when the check engine light comes on in a 2021 Land Rover Discovery Sport?
- It indicates the vehicle's engine management or emissions system has detected a fault; severity ranges from minor to urgent.
- The code could point to anything from a loose fuel cap to a misfire or emissions component failure—only a proper scan will clarify.
- At Park Place Land Rover, factory-trained technicians use OEM diagnostic tools to confirm root causes and recommend repairs that protect long-term value.
- Many issues are covered or influenced by warranty terms; any covered repairs must be completed at a certified dealership to ensure coverage.
How much does a check engine light diagnostic cost for a 2021 Land Rover Discovery Sport?
- Diagnostic fees vary; typical dealer diagnostics range from a modest flat fee to a comprehensive inspection depending on scope and testing required.
- If the diagnostic identifies a repair, our parts and labor pricing often delivers immediate and long-term savings compared with independent shops, while providing factory-trained expertise.
- Many issues are covered by warranty—warranty repairs must be done at a certified dealership to maintain coverage and maximize savings.
- Ask about current service specials and transparent estimates before work begins to see how we reduce total cost of ownership.
What is the first thing to check when the check engine light comes on?
- Start by checking the gas cap: a loose or damaged cap is a frequent, simple cause and can clear the code after a few drive cycles.
- Check oil level and look for other dashboard warnings—multiple lights can indicate broader issues that require immediate attention.
- Avoid repeatedly clearing codes; this can mask ongoing issues and may void warranty considerations—have our technicians run a proper scan instead.
- If the light is flashing or you notice performance problems, stop driving and bring the vehicle to the dealership for urgent inspection to prevent further damage.

2021 Land Rover Discovery Sport Check Engine Light Flashing
A flashing check engine light on a 2021 Land Rover Discovery Sport typically signals a severe condition such as an active misfire that can rapidly damage the catalytic converter and surrounding components. When the light flashes, avoid driving aggressively and have the vehicle inspected immediately—continuing to drive risks costly repairs and further engine harm. Our dealership will prioritize a swift, accurate diagnosis using OEM tools and recommend the correct repairs, often avoiding secondary damage and expensive downstream repairs. Warranty-covered issues must be repaired at a certified dealer, and early intervention with Park Place Land Rover often minimizes total repair costs while maintaining factory-level protection.
2021 Land Rover Discovery Sport Check Engine Light Codes
Common check engine codes for the 2021 Land Rover Discovery Sport include O2 sensor faults (e.g., P0135), catalyst efficiency (P0420), misfire codes (P0300–P0304), fuel trim issues (P0171/P0174), and EVAP system leaks (P0440/P0455). Left unaddressed, O2 sensor failures can reduce fuel economy and lead to catalytic converter damage; replacing an O2 sensor typically ranges from a modest parts-and-labor cost to a few hundred dollars. Ignored misfires can cause severe engine and exhaust damage—repair costs escalate quickly. EVAP leaks are usually inexpensive to fix but will fail emissions tests if neglected. Timely dealer diagnosis and repair protect performance and lower overall ownership costs.
