When buying a used 2013 Renault Laguna 2.0 d, the most frequently mentioned issue is DPF clogging and related sensor pipe problems. EGR valve and intake manifold clogging are also commonly reported.
Engine: M9R
M9R · turbo petrol · 2.0 d · Used in this car from 2007-2015
Strengths
Low fuel consumption
High engine lifespan with proper maintenance
Watch-outs
Demanding fuel system with piezo injectors
Relatively modest timing chain lifespan
Oil separator not always effective
Known engine issues
Fuel systemBosch piezo injectors are demanding on diesel quality and have poor repairability, but the main issues are caused by unreliable fuel pressure regulators. Diagnosis of poor starting or floating idle should start with them.
Timing chainThis engine was developed jointly with Nissan engineers, so the timing drive is chain-based. Opinions on its lifespan vary greatly: some claim 400,000 km on the original chain, while others needed replacement at 150,000 km.
TurbochargerAll versions of these diesel engines are equipped with reliable Garrett turbochargers, but boost errors appear regularly. Usually the vacuum system, boost sensor, or sticking variable geometry mechanism is at fault.
Listed from most frequently reported, each with its source.
DPF clogging and related sensor pipe problems
Often reported
The DPF can clog if the vehicle is predominantly used in city or short-distance driving because regeneration cannot occur. Additionally, the DPF differential pressure sensor pipe may crack or become dislodged, causing warning lights and abnormal behavior.
Exhaust Emissions
EGR valve and intake manifold clogging
Often reported
In the M9R engine family, carbon buildup in the EGR valve and intake manifold is common; this can cause idle fluctuation, power loss, and the check engine light to come on.
Exhaust Emissions
Injection system / injector problems
Often reported
Some 2.0 dCi M9R engines have reported failures in injectors or other common rail injection system components.
Fuel System
Turbo / Wastegate wear or failure
Often reported
Turbo or wastegate failure has been reported in the M9R family; symptoms may include power loss, abnormal noises, smoke, or the engine warning light. The wastegate mechanism can stick, or the turbo may wear due to poor maintenance or heavy use.
