2006 SEAT Ibiza 1.9L Diesel · WD55 UOS

A twenty-year-old SEAT Ibiza carrying 170,934 miles presents a roadworthiness picture defined less by outright component failure and more by a slow, multi-year accumulation of advisories centred on structural corrosion and brake wear. The most recent test on 25 July 2026 was recorded as a pass, but only after flagging a front wiper blade defect, a deteriorated headlamp lens, and an oil leak from the front of the engine. Looking further back, the test on 7 March 2024 resulted in a failure due to a serious fluid leak from the nearside front shock absorber, an item that warrants close attention given its direct bearing on damping and wheel control. Across the 2023, 2024 and 2025 tests, advisories for pitted and scored brake discs at all four corners have reappeared year after year, suggesting the discs have been on the limit of serviceability for some time and may now require replacement. Most concerning from a structural standpoint are the recurring advisories for corroded and fractured underbody and wheel arch metal recorded in 2023 and 2024, indicating that rust is an active and ongoing process on this chassis. Against a vehicle age of around twenty years, the recorded annual mileage of roughly 8,547 miles is broadly in line with average usage, although the spread between MOT dates (with intervals of fourteen months at one point) suggests the car may have had periods of lighter use or short gaps in annual testing. Mileage has therefore accumulated steadily rather than aggressively, which limits the risk of high-speed drivetrain wear but does nothing to mitigate the slow oxidative damage that age alone brings to a unibody structure. The presence of several multi-year advisories for the same areas, particularly brakes, suspension links and underbody corrosion, indicates that wear and corrosion are progressing gradually rather than catastrophically, and the buyer should treat each recurring advisory as an item that has likely worsened since it was last noted. For a prospective buyer, the priority on any inspection should be the underbody and wheel arches. The advisories referring to rusty wheel arches, corroded inner wings and general suspension corrosion in 2021, 2023 and 2024 imply that structural metalwork may now be thinning, and a thorough examination from beneath the car with a torch is essential, paying particular attention to suspension mounting points, the front subframe and the seam where the wheel arch meets the sill. On a test drive, listen for clonks or knocks from the front suspension over uneven roads, as the offside front anti-roll bar linkage ball joint flagged with slight play in 2025 and the nearside front shock absorber fluid leak from 2024 are both areas where deterioration would manifest as poor wheel control, vibration through the steering or unusual body movement under braking. The brake pedal should be checked for any judder or pulse under firm application, given the repeated pitted and scored disc advisories on all four corners, and a visual check of the disc faces through the wheels will reveal whether the wear has progressed beyond what was recorded. Further checks should focus on the engine bay and steering geometry. The front oil leak recorded in the most recent test should be traced to identify whether it originates from the cam cover, sump or oil filter housing, and the buyer should look for fresh oil residue on the lower crankcase and on any undertray that remains fitted. With track rod end dust covers noted as deteriorated in 2022 and constant velocity boots flagged as severely deteriorated in 2021, the steering and front driveshafts deserve particular attention; on a test drive, listen for clicking from the front hubs on full lock and check for any excess play in the steering or uneven tyre wear across the front axle. Finally, given that headlamp lens deterioration, wiper blade defects and inoperative fog lamps have all been noted at various points, a simple functional check of all exterior lights and wipers should be carried out, as these minor items have a habit of accumulating on older vehicles and can quickly add to remedial costs.
