Strengths
Very economical engine
Installed in many European models
Watch-outs
Many problems in early years
Not common on used market
Frequent oil consumption
Known engine issues
Recall campaignEarly diesel engines suffered from loss of tightness at the cylinder head and block joint. A large-scale recall campaign was conducted, and many of these engines were replaced under warranty.
Oil consumptionThe most common problem is oil consumption, usually caused not by wear of oil scraper rings or valve stem seals, but by turbocharger failure.
Oil leaksAnother weak point is the crankcase ventilation system, which quickly clogs, causing oil to enter the intake and leak from seals.
Listed from most frequently reported, each with its source.
Clogged EGR Valve
Often reported
Many Toyota diesel engines (including the D4D in the E140/E150 family) can experience carbon buildup in the EGR valve; this can cause idle fluctuation, intermittent check engine light, torque loss, and DPF regeneration issues.
Exhaust Emissions
Expensive Injectors / Piezo Switchover
Often reported
Toyota diesel engines reportedly switched from repairable electromagnetic injectors to more expensive and less repairable piezo injectors after 2008, making injector repairs more costly.
Fuel System
MMT Transmission Behaviour (MMT versions)
Often reported
On 1.4 D4D versions with MMT transmission, less smooth gear changes, jerky city driving, robotic behaviour, and a more sensitive driving feel are reported compared to traditional manual transmission.
Transmission
Turbo Issues at High Mileage
Often reported
The 1.4 D4D turbo is generally reliable, but failures can occur at high mileage (pressure loss, compressor play, worn wastegate) and significantly reduce performance.
