The Renault L7X 713 is a 2,188 cc, V6 turbo‑diesel engine produced between 1998 and 2002. It was Renault’s first mass — produced V6 diesel, featuring a 60° bank angle, dual overhead camshafts (DOHC), and a Garrett variable geometry turbocharger. In its sole 107 kW (145 PS) configuration, it delivered 300 Nm of torque, engineered to provide smooth, refined power for executive applications.

The Renault L7X 713 is a 2,188 cc V6 turbo‑diesel engineered for executive sedans (1998-2002). It combines Bosch VP44 rotary injection with a variable‑geometry turbocharger to deliver refined, linear power and strong mid-range torque. Designed to meet Euro 3 standards, it prioritizes smoothness and drivability over ultimate efficiency.

The Renault L7X 713 was used exclusively in Renault's front-wheel-drive executive platforms with transverse mounting. This engine received no significant platform-specific adaptations, as it was fitted only to the Laguna I (Phase 2) and Safrane. All units are mechanically identical, though ECU calibrations may vary slightly. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The L7X 713's primary reliability risk is dual-mass flywheel (DMF) failure, with elevated incidence in vehicles subjected to high-torque loads or aggressive driving. Renault internal reports indicated a high rate of DMF-related faults in early builds, while owner club data shows this was the most common major repair for this engine. The high torque output makes proactive DMF inspection and using the revised part critical.
Analysis derived from Renault technical bulletins (1998-2002) and aggregated owner club repair data (2005-2020). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The L7X 713 is a robust and smooth engine with a chain-driven design, but its main weakness is the dual-mass flywheel, especially in early builds. Vehicles from late 1999 onwards with the revised DMF are significantly more reliable. Longevity depends heavily on using high-quality fuel to protect the VP44 pump and addressing any DMF symptoms immediately to prevent further damage.
The most frequent issues are dual-mass flywheel failure, Bosch VP44 injection pump failure due to contaminated fuel, EGR valve clogging, and oil leaks from the valve covers or rear main seal. These are well-documented in Renault service bulletins and owner reports, with the DMF being the most prevalent major repair.
This unique 2.2L V6 diesel was fitted exclusively to the Renault Laguna I (Phase 2, 1998-2001) and the Renault Safrane (1998-2000). It was marketed as the '2.2 dT' and was Renault’s flagship diesel engine at the time, offering a smooth and powerful alternative to four-cylinder diesels.
Aftermarket ECU tuning is common on the L7X-713 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Moderate for its size and performance. In a Laguna I 2.2 dT, expect around 7.5-8.5 L/100km (38-33 mpg UK) on a combined cycle. The Safrane, being heavier, might return 8.0-9.0 L/100km (35-31 mpg UK). Real-world economy is highly dependent on driving style, as the V6 encourages a more relaxed, higher-speed cruising style.
Yes. The L7X 713 is an interference engine. If either of the timing chains were to fail, the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the chains are very durable with proper oil maintenance and rarely fail if serviced correctly.
Renault specifies RN0700 specification oil, typically 10W-40. This is a conventional high-detergent oil suitable for the Bosch VP44 injection pump. Using a lower viscosity oil can lead to pump failure. Change intervals should not exceed 15,000 km or 1 year to ensure optimal engine and pump protection.
