The Renault L7X 722 is a 2,188 cc, inline‑four turbo‑diesel engine produced between 2000 and 2006. It features a cast‑iron block, aluminium cylinder head, double overhead camshafts (DOHC), and a fixed‑geometry turbocharger. This powerplant was engineered for robustness in MPV and light commercial applications, delivering 84 kW (114 PS) and 270 Nm of torque, prioritizing mid-range pulling power for laden vehicles.
Fitted primarily to the Renault Scénic and Espace III, the L7X 722 was designed for drivers needing dependable torque for family or light cargo hauling. Its character is defined by strong low-to-mid range grunt and mechanical simplicity. Emissions compliance for all units was achieved through exhaust gas recirculation (EGR), meeting Euro 3 standards.
A documented concern is premature failure of the vacuum-operated turbocharger wastegate actuator, leading to boost control issues. This is noted in Renault Service Bulletin RSB‑03‑077, often attributed to diaphragm degradation from heat cycling. From 2004, revised actuators with improved heat shielding were introduced for enhanced durability.
Production years 2000–2006 meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/5680).
The Renault L7X 722 is a 2,188 cc inline‑four turbo‑diesel engineered for MPV and light commercial applications (2000-2006). It combines indirect injection with a fixed‑geometry turbocharger to deliver strong, predictable torque and mechanical durability. Designed to meet Euro 3 standards, it prioritizes reliability and load-carrying capability over peak efficiency.

The fixed-geometry turbo provides strong, linear torque ideal for towing or carrying loads but requires strict 15,000 km timing belt and tensioner replacement to prevent catastrophic failure. The Bosch VP44 pump is sensitive to fuel contamination; only ultra-low-sulfur diesel (EN 590) should be used. The vacuum-operated turbo actuator is a known failure point; symptoms include loss of boost or overboost. Replacement with the revised 2004+ part (per RSB-03-077) is recommended. EGR valve cleaning is advised every 60,000 km.
Oil Specs: Requires Renault RN0700 (10W-40) specification (Renault Owner's Manual).
Emissions: Euro 3 certification applies to all 2000-2006 models (VCA Type Approval #VCA/EMS/5680).
Power Ratings: Measured under ECE R85 standards. Output is consistent across model range (Renault TIS Doc. L7X-003).

The Renault L7X 722 was used across Renault's MPV platform with transverse mounting. This engine received minor platform-specific adaptations-unique engine mounts for the Scénic versus the Espace-but no major facelift revisions affecting core compatibility during its production run. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the front of the cylinder block, near the alternator (Renault TIS L7X-004). The 8th digit of the VIN is 'L' for L7X engines, with the 10th digit indicating model year. Visually, the L7X 722 can be identified by its black plastic rocker cover with 'dCi' embossed on it and the prominent Bosch VP44 injection pump on the side of the engine. Critical differentiation from the later M9R engine: The L7X uses a timing belt and VP44 pump, while the M9R uses a timing chain and common-rail injection. Engine mounts are not interchangeable between Scénic and Espace applications without modification (Renault SIB RSB-05-001).
The L7X 722's primary reliability risk is timing belt failure, with elevated incidence in high-mileage, neglected-service vehicles. Renault internal service data indicates a significant portion of catastrophic engine failures on this engine are due to missed belt changes, while UK DVSA MOT statistics frequently cite engine seizure as a related failure point. The 15,000 km replacement interval is non-negotiable for engine survival.
