"Is the L200 2.5 d reliable, and what should you check?"
When buying a used Mitsubishi L200 2.5 d 2011 (2nd generation / facelift), the most commonly reported issues are: Turbo / VGT failures and intercooler hose problems. Also, Instrument Cluster / ECU faults (speed/gauges) are frequently reported.
Engine: 4D56
4D56 · 2.5 d · Used in this car from 2010-2015
Strengths
Good service life with proper maintenance
Many different modifications available
Watch-outs
This engine is very afraid of overheating
Too many weak points in the design
Constant oil or coolant leaks
Known engine issues
Cracks in the cylinder headThis diesel unit is afraid of overheating and the cylinder head gasket blows regularly. But replacing the gasket is not enough; you have to grind the mating surfaces. After a couple of blowouts, cracks are often found near the valves or prechambers.
Crankshaft breakageAnother serious problem of this engine is crankshaft breakage, and this often happens during prolonged driving at low engine speeds. In engines with Common Rail, the crankshaft journals are thicker and breakage is less common.
Fuel system issuesFor obvious reasons, the fuel system causes the most trouble for owners of such diesels, both for swirl chamber and Common Rail versions. Listing all the problems is pointless; this is a topic for a separate and very large article.
Listed from most frequently reported, each with its source.
Turbo / VGT failures and intercooler hose problems
Often reported
In the L200's turbodiesel engines like the 4D56, turbocharger (including variable geometry actuators / wastegate or oil lines) failures or malfunctions, and turbo/intercooler hoses frequently coming loose or cracking are common.
Turbo
Instrument Cluster / ECU faults (speed/gauges)
Often reported
Owners report instrument cluster failures or abnormal ECU communications; for example, the speedometer not working, odometer not updating, and the engine warning light coming on without entering limp mode.
Electrical
DPF (Diesel Particulate Filter) problems and regeneration issues
Often reported
Owners report difficulties with the DPF: incomplete or faulty regenerations, pressure/exhaust temperature sensor anomalies, increased smoke and power loss due to filter clogging.
Exhaust Emissions
EGR valve clogging and carbon buildup
Often reported
The EGR valve tends to clog with carbon deposits over time in common rail diesel engines; for the 2.5 DID, this can cause rough idle, torque loss, jerky throttle response, and the check engine light coming on.
