What This Data Means
The ranked table above shows which Land Rover engines generated the most replacement enquiries in our 2025 UK data. It is not a reliability ranking in the way a survey of every Land Rover on the road would be. Enquiry volume reflects vehicle parc size, age profile, and owner behaviour as much as engineering quality.
What the data does show clearly is which engines are reaching replacement mileage most frequently in the UK right now. The 204DTD and 306DT are the two most common diesel engines across the modern Land Rover range — fitted to Discovery Sport, Evoque, Range Rover Sport, and full-size Range Rover. Their high enquiry count is consistent with their large installed base, not necessarily a sign that they are uniquely problematic.
The R-to-V (Repair-to-Value) flag is arguably more useful than the raw enquiry count. It tells you whether the cost of a reconditioned replacement sits comfortably within the typical value of the vehicle it's fitted to. Almost every engine on this list clears our 60% safety threshold, meaning replacement is financially sound on the typical host vehicle. The two flagged ⚠️ Watch — 276DT and 224DT — are engines most often fitted to older, lower-value hosts (Discovery 3, Freelander 2), where the calculation is closer and worth checking individually.
