The Range Rover 20 T2N is a 4,394 cc, V8 naturally aspirated petrol engine produced between 2006 and 2009. It features sequential electronic fuel injection (EFI), dual overhead camshafts (DOHC), and four valves per cylinder. In standard form it delivers 224 kW (306 PS) and 420 Nm of torque, providing smooth, refined performance with strong mid‑range response.
Fitted to the L322 Range Rover during its mid‑cycle update, including the HSE and Vogue trims, the 20 T2N was engineered for effortless luxury driving with improved emissions control over its predecessor. Emissions compliance was achieved through precise lambda control, secondary air injection, and a three‑way catalytic converter, allowing Euro 4 compliance across all markets.
One documented concern is premature failure of the variable camshaft timing (VCT) solenoid due to oil contamination, potentially causing rough idle, reduced power, and cam timing fault codes. This issue is referenced in Land Rover Service Bulletin LTB00245(08), which attributes the problem to inadequate filtration of engine oil debris in early solenoid designs. From mid‑2008, revised solenoids with improved internal screening were introduced.
All production years (2006–2009) meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/6543).
The Range Rover 20 T2N is a 4,394 cc V8 naturally aspirated petrol engineered for full-size luxury SUV applications (2006–2009). It combines sequential electronic fuel injection with DOHC architecture and variable camshaft timing to deliver smooth, linear power and strong mid-range torque. Designed to meet Euro 4 emissions standards, it balances performance with regulatory compliance and drivability.

The DOHC V8 with variable cam timing provides refined, responsive performance ideal for relaxed cruising and confident overtaking, but requires adherence to 16,000 km or annual oil changes with Land Rover STJLR.03.5002 (5W-30) oil to protect VCT solenoids and timing components. Extended oil intervals increase risk of solenoid clogging and chain wear. Use only RON 95+ fuel; ethanol blends above E5 are not recommended. Post-mid-2008 engines include updated VCT solenoids per Land Rover SIB LTB00245(08).
Oil Specs: Requires Land Rover STJLR.03.5002 (5W-30) specification (Land Rover SIB LTB00245(08)). Equivalent to ACEA A3/B4 with OEM-specific additives.
Emissions: Euro 4 compliance confirmed for all 2006–2009 builds via NEDC testing (VCA Type Approval #VCA/EMS/6543).
Power Ratings: Measured under ISO 1585 standards (Land Rover TIS Doc. L20‑2050).

ISO 1585: Road vehicles — Engine test code
The Range Rover 20 T2N was used exclusively in Land Rover's L322 platform with longitudinal mounting. This engine received platform-specific adaptations—revised engine mounts and updated accessory drive routing—and from mid‑2008 the VCT solenoid was upgraded, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the left cylinder bank near the bellhousing (Land Rover TIS L20‑2090). The 7th VIN digit indicates engine family ('T' for 4.4L V8 petrol DOHC). All 20 T2N units feature aluminum blocks and heads with dual cam covers and a single throttle body. Critical differentiation from earlier 20 H(EFI): 20 T2N uses DOHC with 32 valves and VCT; 20 H(EFI) is OHV with 16 valves. Service parts require production date verification—VCT solenoids before 06/2008 are incompatible with later units due to internal filter upgrade (Land Rover SIB LTB00245(08)).
The 20 T2N's primary reliability risk is VCT solenoid failure on early builds, with elevated incidence in high-mileage vehicles and those with infrequent oil changes. Land Rover internal quality data from 2009 indicated a measurable uptick in cam timing fault codes before 100,000 km, while UK DVSA records show no significant emissions-related MOT failures linked to this engine. Oil degradation and sludge formation accelerate solenoid clogging, making oil quality and interval adherence critical.
Analysis derived from Land Rover technical bulletins (2006–2009) and UK DVSA failure statistics (2009–2025). Repair procedures should follow manufacturer guidelines.
