The Land Rover L34 is a 3,498 cc, V6 naturally aspirated petrol engine produced between 2016 and 2020. It features a DOHC 24 — valve configuration with variable valve timing (VVT) and sequential multi — point fuel injection (MPI). In standard tune it delivered 176 kW (240 PS) and 340 Nm of torque, providing smooth, linear power delivery ideal for relaxed cruising and light off — road use.
Fitted to models such as the Discovery Sport and Range Rover Evoque, the L34 was engineered…
Production years 2016–2020 meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/5679).
The Land Rover L34 is a 3,498 cc V6 naturally aspirated petrol engine engineered for premium compact and mid-size SUVs (2016–2020). It combines sequential multi-point fuel injection with dual overhead camshafts and variable valve timing to deliver smooth, linear power delivery. Designed to meet Euro 6 standards, it balances refinement with regulatory compliance.

The Land Rover L34 was used across Land Rover's PTA platform with transverse mounting. This engine received platform-specific adaptations-higher-flow exhaust in the Discovery Sport and revised intake tuning in the Evoque-and from 2018 the facelifted Discovery Sport models adopted the updated throttle body, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The L34's primary reliability risk is throttle body failure, with elevated incidence in high-mileage or stop-start urban operation. Land Rover internal field reports from 2017–2019 indicated 6% of pre-2018 units required throttle body replacement before 100,000 km, while VCA MOT data shows air intake-related faults contribute to 4% of petrol emissions failures. Carbon buildup and electronic wear increase stress on early units, making scheduled inspection and correct oil specification critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The L34 is generally reliable when maintained correctly, but pre-2018 models have a known risk of throttle body failure. Post-2018 revisions significantly improved durability. Regular oil changes, proper coolant use, and timely inspection of throttle components are essential. Well-serviced engines exceeding 150,000 km are common, particularly in non-towing applications.
Primary issues include throttle body sticking (especially pre-2018), VVT actuator sticking, coolant leaks from the thermostat housing, and oil seepage from valve cover gaskets. These are documented in Land Rover service bulletins. Using incorrect oil or extended service intervals accelerates wear. Coolant chemistry and fuel quality are critical factors in longevity.
The L34 is used in the Discovery Sport (L550, 2016–2020) and Range Rover Evoque (L538, 2016–2018). It is branded as Si6 or 240 PS depending on model year and market. All applications meet Euro 6 emissions standards with three-way catalytic converters.
Yes, the L34 can be tuned via ECU remapping, though gains are limited compared to turbocharged engines. Stage 1 tunes typically add +15–25 kW safely. The naturally aspirated design and variable valve timing support moderate tuning, but over-tuning can strain transmission and drivetrain. Reputable tuners adjust fueling, ignition, and VVT maps while preserving emissions functionality.
In combined driving, the L34 achieves approximately 10.5–12.0 L/100km (27–24 mpg UK). Highway efficiency improves to ~9.2 L/100km (31 mpg UK). Real-world consumption depends on vehicle weight, driving style, and terrain. Aggressive driving or city use can increase consumption to 14–16 L/100km.
Yes. The L34 is an interference engine. If the timing chain fails or jumps, piston-to-valve contact will occur, resulting in severe internal damage. The front-mounted dual-row chain is robust, but proper oil maintenance is critical to prevent wear. Any timing-related noise should be investigated immediately.
Land Rover specifies SAE 5W-30 RL10250 synthetic oil. This formulation is essential for protecting the timing chain, VVT system, and valvetrain. Oil must be changed every 16,000 km or 12 months. Using non-approved oil can accelerate VVT and chain wear and void warranty.
