2006 Daihatsu Terios 1.3L Petrol · WF06 RRY

A pattern of minor and major electrical non-compliances alongside escalating structural and exhaust concerns defines this Terios MOT record. Across four consecutive test cycles, the vehicle has alternated between a clean pass and a failure containing multiple Major defects, with two of those failures involving a Dangerous tyre defect, fractured coil spring, and excessive track rod play in 2022, followed the next year by a cluster of failed emissions readings and MIL illumination, and most recently in 2025 by a corroded rear axle brake pipe. Although a clean pass was recorded on 20 October 2025 following the immediate failure three days earlier, the density and severity of the intervening issues, particularly the brake pipe corrosion and drivetrain/emission faults, signal ongoing mechanical deterioration rather than transient glitches. The 2022 advisories for front tyre wear and perished sidewall cracking further suggest the consumables were already approaching the end of their service life at that point. Against a vehicle age of roughly twenty years, the recorded 90,985 miles equates to an annual accumulation of approximately 4,549 miles, which is notably below typical usage for this class. The MOT history shows consistent year-on-year testing from at least 2022 onwards with no extended gaps in the record, which would normally suggest regular if limited use. However, the mix of low annual mileage and repeated electrical and emissions failures is worth weighing carefully, as short journeys and infrequent running can contribute to moisture accumulation in the exhaust system, catalytic converter under-efficiency, and deteriorated brake pipe surfaces, all of which appear in the recent failure list. The combination of low mileage, a twenty-year-old chassis, and rear axle brake pipe corrosion is particularly relevant, as underused vehicles parked for extended periods often develop surface rust on exposed underbody components that progresses once corrosion initiates. The 2025 failure for a corroded rear axle brake pipe is the most pressing item for any prospective buyer to verify has been properly rectified with a genuine replacement section rather than a temporary repair, and the system should be inspected for any further corrosion on the nearside, offside, and flexible hose unions along the underside. Given the 2022 failures for a fractured offside rear coil spring, excessive play in the offside track rod end ball joint, and structurally torn rear tyres, a close inspection of the remaining coil springs for sagging and any knocking from the rear suspension over bumps is essential, along with a check of the front suspension arms, bushes, and steering rack for renewed play. The 2024 failure for a split nearside front outer CV boot and the constant velocity joint should be confirmed as having been replaced with a proper grease-packed boot and gaiter, with the joint itself checked for clicking on full lock turns during a test drive. The cluster of failed emissions items in 2024, covering hydrocarbon, carbon monoxide, and Lambda readings alongside an illuminated malfunction indicator lamp, points to a possible catalytic converter, oxygen sensor, or engine management fault. A test drive should include observing whether the MIL is functioning correctly when the ignition is switched on and whether it extinguishes once the engine is running, and any hesitation, rough idle, or flat spots under acceleration should be noted. The 2023 failure included non-functioning position and fog lamps and an insecure registration plate lamp, all of which are inexpensive but symptomatic of the general electrical upkeep on the vehicle. Given the Terios is now two decades old, a thorough pre-purchase inspection on a ramp focusing on underbody corrosion, suspension component integrity, brake hydraulic condition, and exhaust system soundness would be prudent before committing to purchase.
