The Renault M9R 724 was used in Renault's premium passenger platforms with transverse mounting. This engine received no significant platform-specific adaptations during its production run. All applications 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.
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 M9R 724 is a powerful and refined engine, but early models (pre-2008) have a known issue with the timing chain tensioner. Addressing this with the updated part and adhering to strict oil change intervals (20,000 km) is crucial. With proper maintenance, including regular DPF regeneration, it can be very reliable long-term.
The most frequent issues are premature wear of the timing chain tensioner (pre-2008), DPF clogging due to driving habits, EGR valve/cooler clogging, and turbocharger actuator failure. These are well-documented in Renault service notes and owner reports.
This engine was primarily used in the Renault Laguna III (2007-2010) and Renault Espace IV (2006-2010), badged as the 2.5 dCi 175. It was also used in certain European Nissan Navara (D40) and Samsung SM5 (L43) models during the same period.
Aftermarket ECU tuning is common on the M9R-724 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.
In a Renault Laguna III, expect real-world fuel economy of approximately 7.5 L/100km (38 mpg UK) combined. The heavier Espace IV will consume slightly more, typically around 8.5 L/100km (33 mpg UK). Fuel economy is highly dependent on driving style and DPF regeneration cycles.
Yes. The M9R 724 is an interference engine. If the timing chain fails or jumps due to tensioner wear, the pistons will collide with the valves, causing catastrophic internal engine damage. Addressing tensioner noise immediately is critical.
Renault specifies an oil meeting the ACEA B4 standard, typically a 5W-40 viscosity for this engine. Using the correct specification is essential for protecting the timing chain and turbocharger, especially under high load and temperature conditions.
