2006 Toyota Yaris 1.4L Diesel · FN06 SWZ

The most recent MOT outcome for this 2006 Toyota Yaris was a pass issued on 29 May 2026, but it is worth noting that this pass was recorded on the same date as a prior failure which cited major defects relating to the offside front headlamp, specifically that it was not functioning on dipped beam and that the light source carried a product contamination severely reducing its light output. The advisory issued alongside that test and carried into the pass noted front brake disc wear, though not judged excessive. Looking back across the available history, the 2025 test passed with advisories concerning rear coil spring corrosion on both sides and ongoing brake pad and disc wear at the front, while the 2024 test was a clean pass with no advisories whatsoever. The 2023 test flagged nearside and offside front brake pad wear. Overall, the trend is one of a generally well-maintained vehicle but with a recurring pattern of front brake wear progression and the recent introduction of structural corrosion concerns at the rear suspension. The latest major failure was clearly rectified prior to the recorded pass, but the underlying lighting defect warrants verification. With 73,580 miles accumulated over approximately twenty years, this Yaris has covered a modest 3,679 miles annually, which is well below typical usage rates and suggests either genuinely light driving or extended periods of standing. Such low annual mileage reduces wear on the engine internals, clutch and transmission but increases the likelihood of age-related deterioration in seals, gaskets, brake calipers, coolant, and brake fluid due to calendar-based degradation rather than mechanical exhaustion. Standing periods also tend to promote corrosion on ferrous components and can lead to brake caliper seizure through lack of regular use. The mileage sequence across the recorded MOTs appears consistent, with no signs of rapid accumulation or clock anomalies, which is reassuring for provenance purposes. From the defect history, the front brake system has been a recurring advisory item across three of the four recorded tests. The brake pads have been noted as wearing thin on both sides since 2023, and front brake disc wear was flagged in both 2025 and 2026. On a test drive, the buyer should listen for any brake shudder through the steering wheel under firm application, which would suggest disc run-out or uneven wear, and feel for the pedal becoming soft or travelling further than expected, which could indicate caliper slider issues given the low usage. The discs may now be approaching the point where they require machining or replacement, particularly as pads that were merely wearing thin two years ago could now be closer to minimum material thickness. The rear coil spring corrosion advisory from 2025 is a more serious structural finding, as corroded coil springs can fracture without warning, particularly under load. The buyer should have the vehicle inspected on a ramp to check for any visible cracking, scaling, or flaking of the rear springs, and should listen for any clonking noises from the rear suspension over uneven surfaces. Beyond the recorded advisories, age-appropriate inspections are strongly recommended for a vehicle of this vintage and usage profile. The tyres should be closely examined for sidewall perishing and cracking, as rubber degrades with age regardless of tread depth, and any tyres over six years old should be replaced on safety grounds. The 12-volt battery is likely original or of significant age and should be load tested, as a marginal battery in a low-mileage car can cause starting issues and may not have been cycled sufficiently to maintain its capacity. Brake fluid should be replaced on a calendar basis regardless of mileage, having absorbed moisture over two decades, and the cooling system requires a fresh flush given the age of the original coolant. The exhaust system, being largely ferrous, should be checked for corrosion at joints, mounting rubbers, and the rear silencer, while the underbody should be inspected for any standing corrosion that may compromise structural integrity. Finally, confirm the service book stamps and verify that the timing chain or belt, whichever applies to this Yaris variant, has been replaced at the manufacturer-specified interval, as neglect of this item can result in catastrophic engine failure.
