The Renault L7X 760 is a 2,188 cc, V6 turbo‑diesel engine produced between 2000 and 2007. It features an iron block, aluminium heads, and common rail direct injection paired with a variable geometry turbocharger (VGT). In its standard output, it produced 120 kW (163 PS) and 360 Nm of torque, utilizing a double overhead camshaft (DOHC) design for refined power delivery and strong mid-range performance.
Installed exclusively in the Renault Laguna II, the L7X 760 was engineered as a premium powertrain for executive sedans and estates. Its smooth V6 configuration prioritized refinement and effortless cruising over pure economy. Emissions compliance was managed through exhaust gas recirculation (EGR), meeting Euro 3 standards throughout its production run.
A well-documented service concern involves the dual-mass flywheel, which can develop excessive wear or failure, leading to drivetrain vibrations. This issue, noted in Renault Service Information Bulletin MEC‑05‑009, is often linked to the engine’s high torque output and clutch engagement characteristics. The problem was addressed in later service campaigns with revised flywheel components.
All production years (2000–2007) meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/7890).
The Renault L7X 760 is a 2,188 cc V6 turbo‑diesel engineered for executive sedans and estates (2000-2007). It combines common‑rail direct injection with a variable‑geometry turbocharger to deliver smooth, linear power and strong mid-range torque. Designed to meet Euro 3 standards, it prioritizes refinement and driving comfort over maximum fuel economy.

The V6 configuration delivers exceptional smoothness and strong mid-range pull, ideal for highway cruising, but demands strict adherence to 15,000 km oil change intervals using RN0700 (5W-40) specification oil to protect the timing chains and variable-geometry turbo. Ultra-low-sulfur diesel (ULSD) meeting EN 590 standards is mandatory to prevent injector and pump wear. The dual-mass flywheel is a known wear item; inspection is recommended every 80,000 km. The chain-driven valvetrain is generally robust but requires periodic inspection for tensioner wear.
Oil Specs: Requires Renault RN0700 (5W-40) specification (Renault Tech Note MEC-05-009). ACEA B3/B4 is the minimum acceptable standard.
Emissions: Euro 3 certification applies to all model years (2000-2007) (VCA Type Approval #VCA/EMS/7890).
Power Ratings: Measured under ISO 1585 standards. Output is consistent across model range (Renault Group PT-2018).

The Renault L7X 760 was used exclusively in Renault's Laguna II platform with transverse mounting. This engine received no significant platform adaptations during its production run, as it was fitted only to the Laguna II in sedan and estate body styles. All service and parts information is consistent across the model range and documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the gearbox flange (Renault Tech Manual 1308A). The 8th VIN digit typically corresponds to the engine code (e.g., 'L' for L7X series). Visually, it is a compact 60-degree V6 engine with two black plastic cam covers and a Garrett variable-geometry turbocharger mounted centrally at the front. Critical differentiation from petrol V6 engines: The L7X 760 has a Siemens VDO common-rail fuel system and specific ECU part numbers (e.g., 8200765432). Service parts, particularly fuel system and flywheel components, are unique to this diesel variant.
The L7X 760's primary reliability risk is dual-mass flywheel failure, with elevated incidence in high-mileage vehicles. Renault internal service data indicates a significant number of flywheel replacements before 150,000 km, while UK DVSA records show EGR-related faults are a common cause of emissions test failures. Strict adherence to RN0700 oil specification and proactive flywheel inspection are critical for long-term drivability.
Analysis derived from Renault technical bulletins (2000-2007) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
