2016 SEAT Leon 1.8L Petrol · LS16 URP

A recurring pattern of shock absorber oil misting across three consecutive MOT tests, coupled with two tyre-related failures on the nearside front, defines the mechanical profile of this SEAT Leon. The shock absorbers have attracted light oil misting advisories at every test since June 2023, appearing first on the nearside front and then spreading to both rear units by 2024. This consistent pattern suggests the dampers are slowly weeping seal fluid and warrant close physical inspection rather than dismissal as cosmetic. The 2026-07-02 test recorded a pass with no defects, which on its own would suggest a clean bill of health, but the failure recorded on the previous day for an excessively cut nearside front tyre deep enough to reach the ply or cords is a salient reminder that tyre condition on this vehicle is an active management issue rather than a settled matter. Two similar nearside front tyre cuts caused failures in both 2024 and 2026, indicating either kerbing susceptibility on that corner or a tendency for the tyres to wear in a manner that exposes sidewall weaknesses. Against an age of roughly ten years, the recorded mileage of 68,770 equates to an annual accumulation of around 6,877 miles, which sits within the expected band for a vehicle of this age and does not point to either long-term storage or exceptionally high use. The testing cadence is consistent year-on-year from 2021 through 2026, with no gaps that would suggest the car was off the road, and mileage progression between tests appears steady. Mechanically, this level of usage is sufficient to have generated normal wear on suspension consumables, brake components, and tyres, but it is not so high as to imply imminent major drivetrain deterioration. The rear brake disc advisory repeated at the 2024 and 2025 tests points to surface corrosion and pitting consistent with regular urban or short-journey use, where discs do not always fully dry and clean themselves under heavy braking. For a prospective buyer, the priority areas on inspection are the dampers and the brake discs, both of which carry documented wear indicators. The shock absorbers should be physically examined for fresh oil residue on the body and around the top mounts, with particular attention to the nearside front and both rear units, and the car should be driven over uneven surfaces and speed bumps to listen for clonking from worn bushes or knocking that would indicate the misting has progressed to a functional failure. The rear brake discs should be checked for runout and a lipped outer edge, and the pedal should feel firm without judder under moderate braking, as pitted discs can produce vibration and reduced efficiency when wet. The nearside front tyres should be inspected closely for sidewall scuffs or cuts near the wheel rim, and the tracking should be verified, since two failures on the same corner across different test cycles may indicate an alignment issue that accelerates shoulder wear and exposes vulnerable areas of the sidewall. The 2022 advisory noting the offside rear inner tyre running out of shape on its inner edge is another alignment-related indicator worth pursuing, as it suggests the geometry has been a longstanding borderline concern rather than a one-off. During a test drive, the steering should be checked for pulling to either side, particularly under braking, and the car should be driven straight and hands-off on a flat road to detect drift. Aside from these specific areas, a thorough underside inspection for corrosion around the rear axle, subframe, and brake pipe runs would be prudent given the age of the vehicle, and the underside of the engine and gearbox should be checked for any oil residue that might suggest the shock absorber misting is part of a broader sealing issue. The pattern of defects recorded is modest but consistent, and addressing the tyres, dampers, and rear discs would represent the most logical maintenance priorities before this Leon is committed to further use.
