2016 SEAT Leon 1.2L Petrol · BD66 VLE

The 2016 SEAT Leon passed its most recent MOT on 8 July 2025 at 49,425 miles, but the maintenance trend is not improving. A recurring advisory for light oil misting on both rear shock absorbers has now appeared in every test since 2022. The condition persisted through the June 2023 test at 33,152 miles and the July 2024 test at 40,175 miles, and it remains present today. Light misting indicates early internal seal wear rather than an active leak, yet five consecutive years of the same advisory suggests the units are gradually degrading. The vehicle has not been rectifying this fault, and the shocks are likely approaching the end of their service life. The mileage profile is notably low. Covering roughly 4,942 miles per year over a decade, the Leon has done far less than the UK average of 7,000 to 8,000 miles annually. The 2022 to 2025 records show incremental accumulation of about 5,000 to 9,000 miles per year, which is consistent but modest. Such light use can reduce wear on consumables and drivetrain components, yet prolonged periods of standing may have allowed suspension seals to dry and perish, potentially contributing to the persistent shock absorber misting. A buyer should prioritise a close physical inspection of the rear suspension. Both rear shock absorbers need checking for worsening oil dampness, reduced damping response, and any knocking or clunking over uneven surfaces. The rear coil springs and top mounts should be examined for corrosion or cracking, common on low-mileage vehicles that spend extended periods stationary. The rear brake calipers and discs deserve attention too, as infrequent use can lead to binding calipers and uneven disc corrosion. The front tyre advisories in 2022 and 2024, a structural bulge and a sidewall cut, were addressed before the following tests, suggesting at least some basic upkeep was performed. Still, a fresh inspection of all four tyres for age-related sidewall deterioration is prudent on a ten-year-old car. The exhaust system and underbody should be checked for surface corrosion, particularly around mounting points and suspension arms, where low-mileage vehicles can trap moisture and develop hidden rust despite clean bodywork.
