2015 Ford Mondeo 2.0L Diesel · FN15 XGF

The most recent DVSA examination on 11 September 2025 resulted in a Pass, although a single advisory was issued for wear to the front suspension arm rear bushes on both sides, noted as not resulting in excessive movement at the time of test. Reviewing the broader history, this vehicle has achieved a Pass at every MOT since first registration, which is a positive baseline, but the advisory pattern warrants close attention. Front suspension bushes were first flagged in October 2023 and have reappeared on the most recent test, indicating a progressive wear trend rather than a one-off observation. Tyre edge wear advisories appeared in March 2020 and again in October 2023, suggesting recurring rear axle geometry or alignment concerns, while rear brake disc surface deterioration was noted as far back as March 2018. Taken together, the trend is not deteriorating rapidly but is steadily accumulating suspension and chassis-related advisories, which is consistent with a high-mileage vehicle of this age. The recorded mileage of 137,624 miles over approximately eleven years equates to an annual average of around 12,500 miles, which is above the typical UK driving average of 7,000 to 9,000 miles per year. There are no significant gaps in the MOT record and no extended intervals between tests that would suggest long periods of standing unused, meaning the wear profile is genuinely reflective of regular, sustained use rather than calendar-driven degradation. Higher-than-average mileage typically accelerates consumption of brake components, tyres, suspension bushes, anti-roll bar links, and drivetrain fluids, and also increases the likelihood of wear in internal engine components, clutch actuation, and automatic transmission servos if applicable. The absence of any advisories relating to emissions, exhaust integrity, or structural corrosion is reassuring given the mileage, suggesting the powertrain and underbody remain sound, but the chassis consumables are clearly approaching the point at which proactive replacement will be required. Given the recurring front suspension arm rear bush advisory, a prospective buyer should arrange for the vehicle to be inspected on a lift, paying particular attention to any play or movement in the lower control arm bushes when loaded, and listening for clonking or knocking noises from the front end when driving over speed humps, rough surfaces, or during full-lock manoeuvres at low speed. The 2023 advisory also noted both rear tyres worn close to the legal limit and on the edge, which combined with the 2020 identical observation raises the possibility of persistent rear wheel alignment deviation or uneven camber; a four-wheel alignment check would be prudent, and any new tyres fitted should be monitored closely for inner or outer shoulder wear patterns. The 2018 advisory concerning pitted and scored rear brake discs suggests surface corrosion and prolonged light braking use, and a buyer should expect that the rear discs and pads may now be due for renewal, with attention to the condition of the caliper slide pins and guide bushes which can seize on vehicles of this age and mileage. Beyond the documented advisories, a high-mileage 2015 Mondeo warrants a thorough inspection of age and use-related items not always visible during an MOT. Brake fluid should be renewed regardless of current condition, as it is hygroscopic and degrades over time, and the engine coolant, which on later Mondeo diesels or petrol units is often long-life, should be checked for specification and age. The 12V battery is likely on its second or third unit and should be load-tested, particularly if the vehicle is used for short journeys. Inspect the tyres not only for tread depth but for sidewall perishing and cracking, as rubber compounds harden with age irrespective of mileage, and verify that all four tyres are of matching size and compatible speed and load ratings. Check for oil leaks around the cam cover, sump, and turbocharger area if diesel, inspect the condition of the auxiliary drive belt and tensioner, and confirm that the service book or digital service history shows regular maintenance at appropriate intervals. Finally, ensure that any warning lights illuminate and extinguish correctly, that the dual-clutch or automatic transmission changes smoothly through all gears, and that the clutch bite point is consistent and not slipping under load.
