Engine: M9T
M9T · turbo petrol · 2.3 d · Used in this car from 2014-2018
Strengths
Large variety of modifications
Fairly moderate fuel consumption
Watch-outs
Injectors often seize in the cylinder head
EGR valve and DPF clogging
Timing chain stretches at low mileage
Known engine issues
Injector SeizingDue to design features, water often gets onto the cylinder head and injectors, causing them to seize. When removing injectors, rust often falls directly into the engine cylinder block, acting as an abrasive. This often leads to scoring and increased oil consumption.
Timing Chain StretchingOne of the most well-known problems of this engine is the modest service life of the timing chain; it sometimes stretches and requires replacement already at 100-150 thousand kilometers.
Typical ProblemsThis is a modern diesel and it has an EGR valve that tends to coke up, and most versions also have a diesel particulate filter with limited service life.
Listed from most frequently reported, each with its source.
Clogged DPF/FAP
Often reported
The DPF/FAP may experience incomplete regeneration or clogging, especially during short trips or light loads, preventing effective regeneration.
Exhaust Emissions
Clogged/Faulty EGR Valve
Often reported
Commonly reported EGR valve clogging or failure on 2.3 dCi engines: carbon and deposit buildup can cause idle fluctuation, power loss, check engine light, and sometimes error messages; in some cases the issue is also linked to the cooling circuit.
Exhaust Emissions
Injection System and Sensor Issues (Injectors, MAF Sensor)
Often reported
Faults in the common-rail injection system and sensors such as the MAF sensor are reported. Typical symptoms include hard starting, rough idle, and power loss. Some users report temporary improvement after cleaning.
Fuel System
Turbocharger Failures (Boost Loss)
Often reported
Numerous reports point to turbocharger issues: boost loss (lack of boost), intermittent turbo intervention, or power loss above certain revs due to component failure, sometimes without immediate warning light.
