2008 SEAT Altea 1.9L Diesel · OV08 AAU

The 2008 SEAT Altea’s latest MOT test on 2025-10-02 resulted in a passing grade, though it was accompanied by three persistent advisories that suggest a pattern of wear and minor mechanical concerns rather than outright failure. The front tyre wear advisories—both the offside front outer tyre and the nearside front outer tyre showing edge wear and proximity to the legal limit—indicate prolonged exposure to uneven loading or alignment issues, which could stem from misaligned suspension geometry, camber or toe-in faults, or excessive camber angles from worn suspension components. The central front upper oil leak advisory, though not excessive, signals a potential weakness in the engine or transmission oil seal system, particularly around the valve cover or oil pan gasket, which may require closer inspection if the vehicle is driven regularly. The absence of failures in the intervening three MOTs suggests stability in overall roadworthiness, but the recurring advisories warrant attention to prevent further degradation or potential long-term issues. The vehicle’s recorded mileage of 111,320 miles over approximately 18 years represents a moderate annual usage rate of around 6,184 miles per annum, which is within the expected range for a car of this age and model, particularly if it has been used primarily for commuting or light road travel rather than high-mileage driving. However, the consistent oil leak advisories and tyre wear patterns could imply either prolonged periods of inactivity with the engine running, leading to oil degradation and seal wear, or more active use that accelerates component fatigue. The absence of significant mileage spikes in the MOT history does not necessarily rule out rapid wear in specific systems, such as the suspension or drivetrain, where high-frequency use could exacerbate wear on bushings, bushings, or seals. The low annual mileage might also suggest that the vehicle has spent considerable time stationary, which can exacerbate issues like brake disc corrosion, caliper binding, or fluid degradation due to stagnation. For a prospective buyer, the tyre advisories should prompt a thorough inspection of the front tyres for signs of uneven wear patterns beyond just the edge wear noted in the MOT. Check for lateral grooves, tread depth uniformity, and any signs of hydroplaning susceptibility, as edge wear can indicate alignment or camber issues that may worsen with further use. Listen for any clunking noises from the front suspension during cornering or over bumps, which could signal worn suspension bushes, coil spring damage, or misaligned struts. The oil leak advisories necessitate a visual inspection of the engine bay for signs of oil pooling around the valve cover, oil pan, or transmission area, and a check for oil consumption or smoke during cold starts. If the leak persists, consider testing for oil pressure under load to rule out a failing oil pump or damaged crankshaft seals. Beyond the mechanical checks, the age and mileage of the vehicle make it prudent to address several age-related wear and tear issues that may not have been flagged in the MOT but are critical for long-term reliability. Begin with a visual inspection of the tyres for sidewall cracking or perishing, which can compromise structural integrity and safety, particularly if the vehicle has been stored in a warm or humid environment. Check the 12V battery for signs of corrosion on terminals, bulging or swelling, or difficulty cranking, as the battery in a high-mileage vehicle may be approaching the end of its service life. Inspect the brake system for signs of corrosion on discs or binding calipers, especially if the vehicle has been stationary for extended periods, as moisture can cause rust buildup that interferes with braking performance. Finally, given the vehicle’s age, consider servicing the engine and transmission fluids according to manufacturer recommendations, even if the last service was not recorded in the MOT history, as fluids degrade over time regardless of mileage. A comprehensive fluid check—including coolant, brake fluid, and transmission fluid—should be performed, with particular attention to the brake fluid for hygroscopic absorption, which can lead to brake system failure. Additionally, verify that all service book stamps are up to date, as the lack of recorded services in the MOT history does not guarantee that maintenance has been completed.
