Toyota Avensis
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.

The 1AD-FTV remains a problem diesel — regardless of body style. Avoid if you're looking for driving fun.
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 11
Faulty airbag control units can store faults and keep the airbag warning light permanently illuminated. In the worst case a malfunction of the restraint system is possible.
The Avensis T270 suffers from insufficient underbody corrosion protection.
Surface rust on axles and floorpan appears as early as 4–5 years. Rust pockets form on suspension components and underbody cross-members, appearing earlier on vehicles from salt-treated roads.
The A/C compressor can fail with age, noticeable by a rattling noise at idle. Refrigerant loss through leaking hoses is also documented.
At higher mileage alternator failure occurs, leading to battery discharge and starting problems. The alternator is one of the most common breakdown points on this model.
Brakes wear above average, especially with frequent motorway use.
Shock absorbers and springs wear faster, especially on high-mileage estate examples.
Number plate lights and sidelights frequently fail at MOT. Headlights drift out of adjustment over time and illuminate unevenly.
Door seals become porous over time and cause pronounced wind noise above 90 km/h. Replacing the outer window seal resolves the problem permanently.
A metallic clicking from the steering shaft when turning is common on the T270. The cause is the steering shaft universal joint. Replacement costs approximately €305 plus labour; cheaper solutions using a modified shaft are available from around €55.
As on the T250, seat heaters and small interior electrical units can fail on the T270. Broken wiring in the movable driver's seat is a known cause. Repair requires seat removal and cable inspection.
