2008 Toyota Yaris 1.3L Petrol · WM08 AOB

The vehicle passed its most recent DVSA MOT test on 17 March 2026, although four advisories were noted covering corroded front coil spring mountings, slight corrosion to the ferrules on both front and rear brake hoses, and an insecure offside rear exhaust heat shield. Looking at the broader test history, the maintenance trend is best described as stable rather than deteriorating, but with a clear age-related pattern now emerging. From a clean pass in mid-2023, the subsequent tests have progressively accumulated advisories relating to corrosion, suspension component wear, and exhaust deterioration, which is entirely consistent with an eighteen-year-old car reaching the stage where its structural and underbody components are subject to natural oxidisation. The only outright failures recorded are repeat presentations for ineffective windscreen wiper operation in 2021 and 2023, which were rectified at the time and have not recurred, indicating no ongoing mechanical concern in that area. At 69,162 miles against an eighteen-year registration, the recorded annual mileage of roughly 3,800 miles is notably low for the vehicle's age and points towards extended periods of standing or only occasional light use rather than consistent daily driving. While this can preserve major drivetrain components such as the engine, clutch, and transmission, low annual mileage introduces its own set of age-related issues that high-mileage examples would not necessarily suffer to the same degree. Long standing periods allow brake calipers to bind due to corrosion on the slider pins and piston seals, brake discs to develop significant surface corrosion that may cause judder on the first applications, and the 12V battery to sulphate and lose capacity despite the relatively modest mileage. Coolant, brake fluid, and automatic or manual transmission fluid also degrade on a calendar basis regardless of use, so a low-mileage car should not be assumed to have recently serviced fluids purely on odometer evidence. Given the advisories recorded across the most recent tests, particular attention should be paid to the front suspension during any inspection. The advisories for corroded front coil spring mountings and corroded front lower suspension arms point towards the early stages of structural corrosion in a critical load-bearing area, which on a Yaris of this vintage should be monitored closely at each annual test. On a test drive, listen for any clunking or knocking from the front end over speed humps, uneven road surfaces, or during sharp direction changes, as this would suggest the rear bushes on the lower arms, noted as worn in the 2024 advisory, have deteriorated further. The brake hose ferrule corrosion advisories on all four corners warrant a physical inspection of the flexible hoses for any surface cracking, blistering, or weeping of fluid under load, and a firm brake pedal application from speed will reveal any sponginess or excessive travel that could indicate the hoses are nearing the end of their service life. Beyond the specific advisories, the general pattern of exhaust corrosion flagged in 2021 and the rear underside corrosion noted in 2024 suggest that the exhaust system and rear underbody should be physically examined for advanced rusting, particularly around mounting brackets, the heat shield fixings flagged as insecure in the latest test, and any visible perforation of the silencer or rear box. The tyres should be carefully inspected for perishing or cracking of the sidewalls and tread face, as tyres older than around six years degrade from age regardless of remaining tread depth, and the date codes on the sidewalls should be checked and dated. Given the low annual mileage, the battery should be load-tested, all fluid levels and their respective service histories should be verified against the book stamps, and the brake calipers should be checked for free movement by ensuring the vehicle rolls smoothly on a level surface without the brakes binding. Finally, confirming the completeness and regularity of the service book stamps will be especially important on a car of this age and usage profile, as it will establish whether the calendar-based servicing requirements such as cambelt, water pump, and coolant renewal have been carried out at the correct intervals.
