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.

All production years (2000–2007) meet Euro 3 standards .
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 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.
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.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The L7X 760 is a robust and smooth engine, but its longevity is heavily dependent on proactive maintenance. The main weakness is the dual-mass flywheel, which is prone to failure at high mileage. Using the correct RN0700 oil and addressing the flywheel issue promptly can result in a very reliable powertrain capable of exceeding 250,000 km.
The most frequent issues are dual-mass flywheel failure causing drivetrain vibrations, EGR valve/carbon buildup, variable-geometry turbo actuator faults, and leaking fuel injector seals. These are well-documented in Renault service bulletins and are common for diesel engines of this era.
The L7X 760 was used exclusively in the second-generation Renault Laguna (Laguna II), produced from 2000 to 2007. It was available in both sedan and estate body styles, badged as the 2.2 dCi 16V.
Aftermarket ECU tuning is common on the L7X-760 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 Renault Laguna II 2.2 dCi, expect real-world figures of around 7.5 L/100km (38 mpg UK) on a mixed run. Highway driving can see figures as low as 6.0 L/100km (47 mpg UK), while city driving might be closer to 9.0 L/100km (31 mpg UK).
Yes. The L7X 760 is an interference engine. If either of the timing chains were to fail or jump, the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the chains are very durable with proper oil changes.
Renault mandates oil meeting the RN0700 specification, typically a 5W-40 synthetic. Using ACEA B3/B4-compliant oil is the absolute minimum. Never use generic or incorrect oil, as it is critical for protecting the timing chains and turbocharger.
