2016 SEAT Leon 2.0L Petrol · NJ66 AAU

The most recent DVSA examination on 6 February 2026 returned a PASS, although two advisories were issued against the rear suspension arms, noting corrosion on both the nearside and offside components that was not deemed serious enough to cause failure at the time of test. Reviewing the broader history, the vehicle has demonstrated a broadly stable maintenance trend, with successful passes recorded at each annual test since 2023 and no major structural or safety-related failures across the documented period. The single failure event dated 28 June 2024 was tyre related rather than mechanical, relating to a nearside front tyre worn close to the legal limit and a dangerous offside front tyre exhibiting a structural bulge in the outer wall. Because advisories on suspension components have only just emerged, this may represent the early stages of a wear pattern that warrants close attention rather than an entrenched problem. The recorded mileage of 67,631 miles on a ten-year-old SEAT Leon equates to approximately 6,763 miles per annum, which sits squarely within typical usage parameters for a vehicle of this age and type. The mileage progression across the MOT records appears consistent and incremental, with no evidence of rapid accumulation that would suggest hard use, nor any significant gaps implying prolonged periods of standing. This steady annual mileage is generally favourable from a mechanical longevity standpoint, as it suggests regular operation and therefore reduced likelihood of issues associated with long-term static storage such as seized brake calipers, perished rubber components, or battery deterioration. Despite the clean overall record, the rear suspension arm corrosion advisories issued at the latest test deserve careful scrutiny during any pre-purchase inspection. Corrosion of multi-link or trailing arm components is a known concern on MQB-platform vehicles of this era, particularly those exposed to winter road salts, and progression from advisory to failure category can occur within one or two test cycles once the corrosion advances through the material thickness. On a road test, listen for clonking or knocking noises from the rear axle over uneven surfaces, speed humps, or when load is transferred during direction changes, as these are classic indicators of compromised bushes or weakened arm material. Visually inspect the arms for advanced surface scaling, flaking, or any signs of thinning around bush housings, and consider a borescope examination of internal box sections if visible corrosion is present, as it can mask more significant internal degradation. Given the age of the vehicle, attention should also be directed towards age-related service items that may not be captured in MOT testing. Tyres should be examined for sidewall perishing and cracking regardless of tread depth, as ten-year-old rubber compounds harden and lose flexibility even with adequate tread remaining, increasing risk in wet conditions. The brake discs should be inspected for lipping, surface corrosion, and any binding caliper stiction, particularly given that the front tyres were replaced in 2024 suggesting active attention to that axle. Verify the age and condition of the 12-volt battery, as original or long-standing units will be approaching end of life, and confirm when the brake fluid, coolant, and timing belt or cam belt were last replaced according to the manufacturer's schedule, as these time-sensitive services are critical on a decade-old vehicle irrespective of its modest mileage accumulation.
