2020 SEAT Leon FR TSI EVO 1.5L Petrol · SP51 LNG

The defining mechanical note across this SEAT Leon's recent testing is the emergence of damping component wear, flagged in the form of light oil misting on three separate shock absorbers at the September 2025 MOT. Both rear units and the nearside front were called out as advisory items at that test, while the most recent assessment on 2 September 2026 returned a clean pass with no defects recorded at all. Four tests are on file, all of which resulted in passes, so the vehicle has not failed an MOT, but the 2025 advisories are not isolated notes. Three shocks misting oil at the same test points to a fleet-wide deterioration rather than a single worn damper, and on a six-year-old car this is the typical age-related pattern one would expect as gas-pressure units begin to weep internally. The fact that no further advisories appeared in 2026 is positive but does not negate what was observed twelve months earlier, as dampers that have started to mist generally continue to degrade. With 46,206 miles recorded over approximately six years, the vehicle is averaging around 7,700 miles annually, which sits broadly in line with typical private use for this class of car. There are no unusual gaps between tests or implausible jumps in odometer readings, so the mileage progression is consistent and there are no signs of extended standing periods that would raise separate concerns. At this annual rate, consumable wear should be moderate, but the suspension, braking, and drivetrain components have still seen meaningful real-world use rather than being preserved by low mileage. The combined effect is a car that has been driven regularly enough to keep seals and joints active, while accumulating the kind of mileage at which original shock absorbers and bushings begin to approach the end of their service life. For a buyer evaluating this Leon, the priority on any inspection should be the suspension system, given the three oil-misting advisories from 2025. On a test drive, pay close attention to ride quality over uneven roads, undulating surfaces, and sharp urban imperfections such as sunken manhole covers or speed humps taken at a normal pace. Audible knocks, a slightly harsh or unsettled ride, excessive bouncing after a single bump, or prolonged oscillation after a speed hump are all classic indicators that the dampers have further deteriorated since they were first noted. Listen for clonking or creaking from the front when pressing the wheel arch down by hand, and feel whether the body settles quickly or continues to oscillate, as a healthy unit should control movement within one or two cycles. Uneven tyre wear, particularly cupped or scalloped patterns on the front pair, can also point to reduced damping efficiency. Beyond the dampers, carry out a thorough walkaround looking for any fresh oil staining on the bodywork or on the shock bodies themselves visible through the wheel apertures, as continued weeping will leave residue. Inspect the front suspension arms, drop links, and anti-roll bar bushes for perished rubber or cracking, and check that the car sits level at both ends when parked on flat ground, since a sagging corner is a strong indicator of a failed damper. Given the clean 2026 result, there is no recorded evidence of brake, exhaust, or structural issues to investigate, but the test drive should still include firm pedal braking from around 30 mph to confirm there is no pull to either side, no vibration through the steering wheel, and no judder that might suggest warped discs. A steady speed test over a winding road will confirm tracking and steering precision, while a brief low-speed manoeuvre will reveal any binding calipers through uneven response or a dragging sensation.
