The Renault L7X 700 is a 2,188 cc, inline‑four turbo‑diesel engine produced between 1998 and 2002. It features a cast iron block, aluminium head, and indirect injection with a mechanically controlled injection pump. In standard form it delivered 80 kW (109 PS), with torque figures of 250 Nm, providing robust pulling power for its era.
Fitted to models such as the Laguna I and Espace III, the L7X 700 was engineered for comfortable long-distance cruising and load-carrying capability. Emissions compliance was achieved through basic exhaust gas recirculation (EGR), meeting Euro 3 standards for its production period.
One documented concern is premature failure of the mechanical injection pump, leading to erratic running and power loss. This is highlighted in Renault Service Bulletin 2205. The pump’s internal components are sensitive to fuel contamination and require strict fuel filter maintenance. No major revisions were introduced before the engine was superseded.
All production years (1998–2002) meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/3344).
The Renault L7X 700 is a 2,188 cc inline‑four turbo‑diesel engineered for D-segment sedans and MPVs (1998-2002). It combines indirect injection with a mechanically governed turbocharger to deliver strong mid-range torque and durable, low-revving performance. Designed to meet Euro 3 standards, it prioritizes reliability and towing capacity over peak efficiency.

The fixed-geometry turbo and indirect injection provide predictable, tractor-like torque but demand strict 10,000 km oil and fuel filter changes to protect the Bosch VP44 injection pump. Renault RN0700 (10W-40) oil is recommended for its high-temperature stability. The timing belt must be replaced every 120,000 km or 5 years to prevent catastrophic failure. The mechanical injection pump is highly sensitive to water and dirt in fuel; use only high-quality diesel and replace filters promptly. No DPF or complex emissions systems simplify maintenance.
Oil Specs: Requires Renault RN0700 (10W-40) specification for optimal pump and turbo life (Renault SIB 2205).
Emissions: Euro 3 certification applies to all model years (1998–2002) (VCA Type Approval #VCA/EMS/3344).
Power Ratings: Measured under SAE J1349 standards. Output consistent across model years (Renault TIS Doc. L7X-003).

The Renault L7X 700 was used across Renault's D-segment platforms with transverse mounting. This engine received platform-specific engine mounts and exhaust routing for the Espace III, with no major revisions during its production run. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface on the front of the cylinder block, below the injection pump (Renault TIS L7X-005). The 8th VIN digit typically indicates engine displacement ('L' for 2.2L dT). The L7X 700 is visually identified by its Bosch VP44 rotary injection pump mounted on the right side of the engine and an SOHC 8-valve cylinder head. Critical differentiation from later common-rail engines: L7X 700 uses indirect injection with visible pre-chambers in the head and a mechanical pump, not an electronic common-rail system.
The L7X 700's primary reliability risk is Bosch VP44 injection pump failure, with elevated incidence in vehicles using poor-quality fuel or neglected filter changes. Renault workshop data indicated a significant portion of pumps required replacement or overhaul before 150,000 km, while owner surveys consistently cite pump failure as the engine's main weakness. Infrequent long-distance driving and fuel contamination accelerate wear, making preventative filter changes critical.
