2009 SEAT Altea 2.0L Diesel · OY09 LLD

The vehicle was presented for its most recent MOT on 25 June 2026 and passed, though five advisory items were recorded against it. Reviewing the trend across the recorded tests, the maintenance picture is one of slow but progressive decline. The earlier tests in 2020, 2021, 2022 and 2023 were all passed with no defects, indicating a period of sound condition, but from 2024 onwards a steady stream of advisories has emerged, and by 2025 a failure was recorded for headlamp aim and a registration plate lamp defect, alongside further brake disc, tyre wear and anti-roll bar advisories. The 2026 test subsequently returned a pass but retained advisories relating to headlamp lens film, brake disc condition, undertray obscuration and exhaust corrosion. This pattern is consistent with an older vehicle entering a phase where wear-related items are accumulating, even though nothing has yet reached the threshold for failure. With 65,169 miles recorded over approximately seventeen years, the vehicle is running at around 3,833 miles per year, which is notably low for its age and suggests either light usage or extended periods of standing between infrequent journeys. Low annual mileage is generally kinder to engines, transmissions and clutches, but it can be punishing on items that suffer from inactivity. Brake discs and calipers can corrode or seize from lack of use, tyres can perish from age rather than wear, coolant and brake fluid degrade by calendar rather than mileage, and the 12V battery is prone to premature failure on cars that are not regularly driven. The MOT history supports this picture, as brake disc corrosion and pitting have been flagged repeatedly on both front and rear units across several consecutive tests, which is a classic indicator of low-use corrosion rather than friction wear. Given the recurring advisory items, a prospective buyer should focus their physical inspection on the braking system first, as front disc wear and pitting was noted in both 2025 and 2026, and rear disc corrosion was recorded in 2024. On a test drive, listen for any clonk or shudder through the steering wheel under braking, which would suggest the discs have worn beyond their serviceable limit and may require replacement rather than skimming. The nearside rear anti-roll bar linkage ball joint play flagged in 2024 should also be rechecked, as worn anti-roll bar links typically produce a characteristic knocking over uneven roads and during direction changes, and replacement bushes or drop links are relatively inexpensive. The exhaust centre sleeve and clamp corrosion noted in 2024 and 2026 should be inspected for any hissing under load or visible blowing at the joint, as corroded sleeves can allow exhaust gases to escape before the catalytic converter. The headlamp lens film advisories, particularly the headlamp aim failure recorded in March 2025, should prompt a check that both units are securely mounted and that the beam pattern sits below the headlight reference line, as any movement of the adjusters can reintroduce that defect. Because mileage has been low, a physical inspection should also cover the items most vulnerable to age and standing. Tyres should be examined closely for sidewall cracking and perishing regardless of tread depth, as rubber compounds degrade with time and MOT advisory records have already shown rear and nearside front tyres wearing close to the legal limit and on the inner edge, which can indicate either alignment irregularities or simply age-hardened rubber. The undertrays noted as fitted in 2026 will need to be removed for a proper inspection underneath, so any corrosion on subframe, suspension arms or brake lines should be checked directly. Brake fluid should ideally be replaced every two years regardless of mileage, and given the vehicle's age the cooling system, power steering fluid and timing belt or chain service history should be verified through the service book, as calendar-based intervals rather than odometer readings are the more relevant measure on a low-mileage car. Finally, a 12V battery load test is strongly advised, as batteries on infrequently driven vehicles frequently fail without warning and can mask underlying electrical faults during a brief test drive.
