Toyota Yaris
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 without spirit
The 1.4 D-4D is economical and long-lived, but in a small car there's no room for driving fun. A pure rationality choice.
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
Vehicle Weaknesses 9
Rear brake discs rust quickly with infrequent use or short-trip driving. Brake pads bond to the disc, resulting in dragging brakes.
Strut top mounts wear at an above-average rate at higher mileages. Results in creaking noises when turning and degraded ride behaviour.
Starter batteries on 2012–2013 build years fail prematurely at a noticeably high rate. Particularly with short-trip use.
The rear wheel arch edges are prone to corrosion, particularly at the fold seam where moisture collects.
The front-mounted A/C condenser is damaged by stone chips and loses refrigerant.
The blower resistor in the heating/A/C system fails, leaving the cabin fan working on only one speed or not at all. Typical wear item from around 80,000 km.
The hose leading to the A/C condenser can develop leaks causing slow refrigerant loss. According to forum reports Toyota was aware of the issue; repair costs approx. €1,000–1,200.
The electric power steering (EPS) of the XP130 can feel too heavy or too indirect. ECU update or steering replacement required. The steering wheel sometimes fails to self-centre fully after cornering.
Hard plastics in the interior, especially the dashboard and door panels, tend to creak with age. At higher mileages wind noise from poorly fitting trim panels occurs.
