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.

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 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The L7X 722 is fundamentally robust with its simple indirect injection and strong bottom end. Its Achilles' heel is the timing belt; failure is catastrophic. Adhering strictly to the 15,000 km belt replacement schedule is paramount. With this and regular oil changes (10W-40 RN0700), it can easily surpass 300,000 km with minimal issues.
The top issues are timing belt failure (if neglected), turbo actuator diaphragm leaks (causing boost issues), Bosch VP44 injection pump failures (often from bad fuel), and glow plug/relay wear. These are well-documented in Renault service bulletins like RSB-03-077 and RSB-04-055.
This 2.2L dCi 115 engine was primarily used in the Espace III (2000-2003) and Scénic II (2003-2006). It was also fitted to early versions of the Master II van (2003-2006), making it a versatile powertrain for Renault's larger vehicles of that era.
Yes, but gains are limited by the VP44 pump and fixed-geometry turbo. A remap can safely increase power to around 130-140 PS and torque to 300-320 Nm. Beyond that, a hybrid turbo and upgraded intercooler are needed. The engine's internals are strong enough to handle moderate increases.
In a Renault Scénic dCi 115, expect real-world figures of 6.5-7.5 L/100km (43-38 mpg UK) on a mixed run, and up to 5.8 L/100km (49 mpg UK) on steady motorway drives. City driving typically yields around 8.0-9.0 L/100km (35-31 mpg UK), which is respectable for a 2.2L MPV engine.
Yes. It is an interference design. If the timing belt fails or jumps, the pistons will collide with the open valves, causing severe and expensive internal engine damage. This is why the 15,000 km replacement interval is absolutely critical.
Renault specifies a 10W-40 mineral or semi-synthetic oil meeting the RN0700 specification. While not as demanding as modern engines, using the correct viscosity and specification is still important for protecting the turbocharger and ensuring smooth operation. Change intervals should be 15,000 km or annually.
