Toyota Auris
Evolution of the 1CD-FTV with a timing chain instead of a timing belt. Considerably more reliable than its predecessor — watch DPF regeneration on short runs. Injectors more durable than on the 1CD.
Diesel Auris without appeal
93 kW 2.0 D-4D in the E140 — torque-rich long-distance engine with zero fun ambitions.
Engine Weaknesses 7
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
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.
Symptoms: Oil level drops rapidly between changes, oil warning light illuminates; blue smoke from a warm engine is possible
Engine damage on the T25 2.0 D-4D caused by cooling system failure has been documented in toyota-forum.de. When the engine overheats, the remaining coolant escapes and the engine loses its thermal protection.
Symptoms: Coolant temperature gauge spikes suddenly, coolant loss, steam from the engine bay
The copper washers under the piezo injectors should be replaced every 60,000 km. If neglected they can burn through and allow hot combustion gas to escape.
Symptoms: Ticking noise from the engine area, rough running, power loss
The EGR valve on the 1AD-FTV tends to heavy soot fouling, especially with short-trip use. From around 100,000 km a clean or replacement is often necessary.
Symptoms: Hesitation, power loss, increased consumption, check engine light (P2002, P0401), engine limp mode.
The DPF on the 1AD-FTV clogs with frequent short-trip use because regeneration temperature is never reached. Fault code P2002 is typical. A motorway run is often sufficient for regeneration.
Symptoms: DPF warning symbol, increased fuel consumption, power loss, vehicle enters limp mode.
The VGT turbo on the 1AD-FTV has a known actuator issue. A case documented in avensis-forum.de describes a turbo failing just after warranty expiry, with Toyota refusing to cover the repair costs.
Symptoms: Power loss, limp mode, black or white smoke, whistling noise from turbo area
Vehicle Weaknesses 10
On models from 2007–2010 the accelerator pedal module can jam due to condensation moisture and stick in the wide-open-throttle position. Toyota carried out a worldwide recall.
Rear brake discs see minimal load and consequently rust through particularly quickly. Early replacement is often necessary.
Headlights and tail lights are flagged above average at MOT. Reflectors become cloudy.
The centre exhaust section corrodes particularly at joints and mounting brackets.
Individual pencil coils fail and cause misfires on a single cylinder.
The rear brake discs corrode excessively when the rear brakes see little use.
A widespread problem on the E150: the electric power steering clicks when turning towards full lock. The cause is overly tight universal joints on the steering column. A recall was issued with steering column reinforcement and damper.
Leak points develop in the A/C condenser of the E150, leading to refrigerant loss. In one documented case only 60 g of refrigerant remained in the system — insufficient for adequate cooling and compressor lubrication.
The window regulator switches on the E150 can be damaged by wear and insufficient lubrication. In individual cases thermal damage from overheating of the switch unit has been documented.
Leaking rubber seals on the tailgate of the E150 allow water ingress into the boot on hatchback variants. Particularly affects older vehicles with worn seals.
