Toyota Auris E140

Compact common-rail diesel with a timing chain instead of a belt, which cuts maintenance effort. Economical and fundamentally solid, but at the limit of its performance in larger bodies and accordingly strained. Typical issues are coking EGR valves and boost/swirl-flap problems from around 150,000 km. Pure short-run use risks a clogged DPF regeneration, so plan regular motorway trips. When buying, check injectors and EGR and watch for black smoke and limp mode. Change the oil consistently every 10,000–15,000 km to the correct specification.

• !! Oil dilution from DPF regeneration from 120,000 km

  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

• !! Faulty fuel pressure regulator valve from 100,000 km

  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

+ 4 more engine weaknesses + vehicle weaknesses

2.0-litre common-rail diesel with a timing chain instead of a belt — the chain is maintenance-free and a clear step up from the belt-driven predecessor. Noticeably more reliable, with more durable injectors. The main issue is still the particulate filter: on pure short-trip use it regenerates poorly, clogs up and causes oil dilution — so check oil level and smell. From around 150,000 km watch for swirl-flap and EGR coking. With regular motorway runs and clean oil, a long-lived compression engine.

• !! Blown head gasket from 120,000 km

  The 1AD-FTV 2.0 D-4D is known for frequent head gasket failures. Despite Toyota recall campaigns for piston replacement, the oil loss problem persisted in many cases.

  Symptoms: Coolant loss, bubbling in the expansion tank, white smoke from the exhaust, milky-coloured engine oil

• !! Elevated oil consumption (despite recall) from 100,000 km

  Progressive oil consumption is a recognised problem on the 1AD-FTV. Toyota carried out piston replacement recalls, but the oil consumption issue often did not disappear completely.

+ 5 more engine weaknesses + vehicle weaknesses

Modern successor to the 2NZ-FE with Dual VVT-i on both intake and exhaust. Economical and reliable; the timing chain normally lasts the life of the engine and needs no fixed replacement. Eager to rev but a touch lethargic low down. The weak spot is slightly raised oil consumption from around 150,000 km, so check the level regularly and keep to a 15,000 km or annual service. When buying, listen for a rattly cold start (chain tensioner) and look for service records. Overall a long-lived, undemanding everyday engine.

• !! Timing chain rattle on cold start from 130,000 km

  The 1NR-FE rattles briefly on a cold start because the hydraulic chain tensioner only works once oil pressure has built up. With neglected oil changes the tensioner valve can block and the chain stretches permanently.

  Symptoms: Metallic rattling immediately after cold start for 1–3 seconds, sounds like a loose metal chain; also audible when warm if the chain is worn

• !! Oil consumption on short-trip use from 120,000 km

  The 1.33 valvetrain shows elevated oil consumption with frequent short-trip use. The oil level should be checked regularly, as the engine can consume up to 0.5 litres per 1,000 km with a poor driving profile.

  Symptoms: Dropping oil level between service intervals without blue smoke; engine runs normally otherwise

  The VVT-i actuator on the 1NR-FE can become blocked by oil deposits with neglected oil changes, causing a phase error and increased fuel consumption.

  Symptoms: Engine warning light with VVT fault code, rough idle after cold start, slight power loss

+ 4 more engine weaknesses + vehicle weaknesses

Solid four-cylinder with VVT-i on the intake side and a timing chain, the predecessor to the fully variable valve-timing variant (1ZR-FAE). Reliable, low-maintenance and economical, eager to rev with adequate if not abundant pull. The timing chain lasts the life of the engine with regular oil changes. Known weak spots are rare — occasionally slightly raised oil consumption and age-related seals at high mileage. When buying, listen for a rattly cold start and look for unbroken servicing. Service every 15,000 km or annually, then an undemanding, long-lived everyday engine.

• !! Accelerator pedal sticking due to condensation (recall) from 50,000 km

  On early Auris models (E150, 2007–2009) condensation on the throttle linkage could cause the accelerator pedal to stick. Toyota issued a recall.

  Symptoms: Noticeably dropping oil level between services, blue smoke from the exhaust on cold start or under acceleration, oil smell after a run

+ 4 more engine weaknesses + vehicle weaknesses

1.6-litre four-cylinder with continuously variable valve lift (Valvematic) that delivers crisp throttle response and low consumption. Economical and responsive enough for daily use, and it revs more willingly than the plain VVT-i version. Timing chain instead of a belt, so no costly interval change. On occasion oil consumption rises from around 120,000 km due to worn valve stem seals, shown by bluish smoke on load changes. The Valvematic actuator can fail and should be checked via the fault memory when buying. With regular oil changes it is a durable, undemanding engine.

+ 4 more engine weaknesses + vehicle weaknesses

Evolution with Valvematic variable valve lift, more economical and refined than the older 1ZZ-FE. Runs a timing chain and is generally regarded as reliable. Oil consumption occasionally rises from 150,000 km as the valve stem seals wear, so watch for bluish smoke on throttle changes when buying. The Valvematic actuator needs clean maintenance and the correct oil at the right interval, otherwise the adjustment can become sluggish. Otherwise a robust, long-lived petrol unit.

• !! Faulty Valvematic control unit from 100,000 km

  The Valvematic actuator on the 2ZR-FAE develops faults, triggers error codes and can stall the engine. Carbon deposits on the intake valves from direct oil contact make the problem worse.

  Symptoms: Rough or stumbling idle, warning light, engine stalling; partial power loss at higher revs

  The timing chain tensioner on the 2ZR-FAE can wear prematurely from around 150,000 km when oil change intervals are neglected. Timely oil changes are critical for the longevity of this component.

  Symptoms: Rattling from the timing chain area on cold start that disappears after a few seconds. With greater wear the noise becomes permanent.
