The Land Rover 23 J is a 1,999 cc, inline-four turbo-diesel engine produced between 2020 and 2023. Part of Jaguar Land Rover's Ingenium engine family, it features high-pressure common-rail fuel injection, a variable geometry turbocharger (VGT), and dual overhead camshafts. In standard tune it delivers 110 kW (150 PS) and 360 Nm of torque, with higher-output versions producing up to 132 kW (180 PS), offering a balance of efficiency and responsive low-end performance.
Fitted to models including the Range Rover Evoque D150/D180, Discovery Sport, and Defender 90/110, the 23 J was engineered for urban efficiency and light off-road capability. Emissions compliance is achieved through a cooled exhaust gas recirculation (EGR) system, diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, enabling adherence to Euro 6d-Final standards across all production years.
One documented reliability concern is premature diesel particulate filter (DPF) clogging, highlighted in Land Rover Technical Service Bulletin P313-0021. This issue arises from frequent short-trip driving and low exhaust temperatures preventing passive regeneration. From 2022, revised ECU calibration extended active regeneration intervals and improved soot burn-off efficiency, reducing DPF-related faults.
All production years (2020–2023) comply with Euro 6d-Final emissions standards (VCA UK Type Approval #VCA/EMS/5680).
The Land Rover 23 J is a 1,999 cc inline-four turbo-diesel engine developed for compact and mid-size SUVs (2020–2023). It integrates variable geometry turbocharging with Bosch CRS 3-20 common-rail injection to deliver strong low-end torque and improved throttle response. Designed to meet Euro 6d-Final regulations, it balances real-world drivability with stringent emissions control through DPF and SCR systems.

The variable geometry turbo provides strong low-RPM torque ideal for off-road crawl and urban driving but requires adherence to 15,000 km oil service intervals to prevent DPF clogging and turbo degradation. JLR STJLR.51.5004 (5W-30) oil is critical due to its low-ash formulation protecting the DPF and SCR system. Short-trip driving inhibits passive regeneration, necessitating periodic highway runs to maintain DPF health. The Bosch CRS 3-20 fuel system demands ultra-low sulfur diesel (ULSD) meeting EN 590 standards to prevent injector wear. Post-2022 models feature updated ECU mapping for improved regeneration; pre-2022 units should have software updated per SIB P313-0021.
Oil Specs: Requires JLR STJLR.51.5004 (5W-30) specification (Land Rover SIB P312-0056). Supersedes ACEA C2 standards.
Emissions: All 23 J engines (2020–2023) comply with Euro 6d-Final standards (VCA Type Approval #VCA/EMS/5680).
Power Ratings: Measured under SAE J1349 standards. 132 kW output requires EU4+ diesel quality (JLR PTS-2020).

The Land Rover 23 J was used across Land Rover's Evoque/Discovery Sport platforms with transverse mounting and adapted for the Defender's longitudinal architecture. This engine received platform-specific tuning-shorter intake manifolds in the Evoque and revised torque mounts in the Discovery Sport-and from 2022 the Defender 90/110 adopted the SCR-enhanced 23 J variant with updated ECU mapping, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front face of the cylinder block near the starter motor (Land Rover TDS ING4D-23). The 8th VIN digit indicates engine type ('D' for Ingenium 2.0L diesel). Pre-2022 models have silver intake manifolds with black plastic covers; post-2022 units use gloss black covers. Critical differentiation from 20 D4: 23 J includes SCR/AdBlue system with underfloor tank. Service parts require production date verification—DPF assemblies for pre-2022 models are incompatible with post-2022 revisions due to internal substrate changes (Land Rover SIB P313-0021).
The 23 J's primary reliability risk is diesel particulate filter (DPF) clogging, with elevated incidence in urban driving cycles. Internal Land Rover quality reports from 2021 noted a significant share of pre-2022 engines requiring DPF cleaning or replacement before 100,000 km, while UK DVSA records link SCR system faults to infrequent AdBlue top-ups in city-driven vehicles. Stop-start operation and low-speed driving increase soot accumulation, making driving pattern and maintenance adherence critical.
