The Discovery Sport D165 was introduced in 2020 as part of a diesel range simplification, replacing the previous D150 and D180 badges. It uses the Ingenium AJ200D or AJ150D — a 2.0-litre four-cylinder diesel that's been a mainstay of JLR's compact SUV range. It's a Euro 6d-compliant unit, fitted to the L550-generation Discovery Sport, and represents the current diesel offering in the range alongside the higher-output D200. Land Rover Discovery Sport D165 Engine Codes Ingenium AJ200D / AJ150D A 2.0-litre four-cylinder diesel fitted to the Discovery Sport D165 from 2020 onwards. It's a common-rail turbo-diesel with a timing chain-driven valvetrain. The Ingenium diesel family is known for timing chain tensioner wear and EGR cooler leaks — which we address as standard on every rebuild. Check Your Ingenium D165 → [link to quote form] Land Rover Discovery Sport D165 Engine Compatibility The D165 is part of a broader Ingenium diesel range, and its compatibility is determined by the L550 generation chassis. Unlike earlier diesel variants, the D165 was introduced with a simplified model range to reduce confusion. Before we quote or supply anything, we confirm: - Your exact engine code via registration or VIN - Your vehicle's generation (L550) - Drivetrain specification (4WD) - Any ECU or emission-control specifics relevant to your exact build This is why we always start with your registration rather than a generic D165 quote — it protects you from compatibility issues and ensures the rebuild matches your exact vehicle.
