Toyota 1.4 D-4D
Compact diesel with timing chain and common-rail injection. Economical and long-lived, but at the limit of its performance in larger vehicles. DPF issues possible in pure short-run use.
Economy diesel in miniature
The 1.4 D-4D in the Yaris Verso is tuned purely for economy. With 75 PS and the higher weight of the Verso, overtaking becomes an exercise in patience.
Engine Weaknesses 6
The 1ND-TV injects extra diesel during DPF regeneration cycles, which finds its way into the engine oil via the piston rings. The oil level rises above the maximum. On short trips the DPF regenerates every 100 km with significantly increased fuel consumption.
Symptoms: Oil level rises above maximum, diesel smell in the engine oil, significantly increased fuel consumption on short trips, frequent DPF regeneration cycles
The fuel pressure regulator valve is the most commonly failed component on the 1ND-TV. Clogged screens from poor quality fuel block the valve. Result: hard starting and power loss above 3,000 rpm.
Symptoms: Hard starting, noticeable power loss above 3,000 rpm, engine warning light, sometimes limp mode
The dual mass flywheel on the 1ND-TV is considered prone to wear and can in the worst case cause a gearbox failure. Typically the DMF and clutch need to be renewed together.
Symptoms: Strong vibrations when pulling away and in the 1,200–2,600 rpm range, rattling and banging from the gearbox area
The EGR valve on the 1ND-TV is the most frequently blocked component on this diesel. Deposited soot particles restrict valve movement; cleaning is often sufficient, but heavy fouling requires replacement.
Symptoms: Power loss above 3,000 rpm, engine warning light, EGR fault code, black smoke on load changes
Early versions of the 1ND-TV were recalled due to turbo issues. The turbo actuator diaphragm can fail. Motorinspektion.de confirms turbo failures as a known weakness of the 1.4 D-4D.
Symptoms: Power loss, black smoke, limp mode, whistling or howling from the turbo area
Excess crankcase pressure on the 1ND-TV forces oil into the intake and exhaust, causing long-term turbo damage. A faulty crankcase ventilation system is cited as a known weakness at motorinspektion.de.
Symptoms: Oil consumption, blue oil deposits in the intake area, power loss, oil mist from the exhaust
