2017 Ford Mondeo 2.0L Diesel · BL66 AAZ

A pattern of late-life advisory wear is now beginning to show on this 2017 Ford Mondeo, with the 2026 test cycle marking a clear departure from the clean run of passes recorded between 2023 and 2025. On 27 August 2026 the vehicle was initially failed on a minor defect for an inoperative nearside rear registration plate lamp, before being re-presented and passing the same day. Alongside that lamp issue, the inspector logged advisories for an oil leak described as not excessive, a nail in the offside rear tyre, and front and rear brake discs noted as worn, pitted or scored but not seriously weakened. A fitted under-tray was also recorded. While none of these items individually constitute a failure, their simultaneous appearance after several years of defect-free tests indicates that the consumable braking components and engine sealing are entering a phase where closer monitoring, and likely near-term replacement, will be required. Recorded mileage stands at 85,116 miles across nine years of age, equating to an annual accumulation of roughly 9,400 miles, which sits comfortably within the expected range for a vehicle of this vintage and type. There are no significant gaps in the MOT testing history, with annual entries recorded from 2023 through to August 2026, suggesting continuous use rather than extended periods off the road. There is no evidence in the record of any dramatic mileage spikes between tests, so drivetrain wear is likely to be broadly proportionate to the odometer reading rather than skewed by inconsistent usage. This consistent accumulation supports a mechanical profile in line with a regularly driven family saloon. For a prospective buyer, the most pressing items to verify on a physical inspection are the brake discs flagged at the last test. Pitting and scoring on the friction surfaces will, as they progress, manifest as vibration through the steering wheel or brake pedal under firm deceleration, accompanied by reduced initial bite and a tendency for the brakes to feel less progressive in wet conditions. It is worth asking whether the discs have since been re-cut or replaced, and inspecting them directly for a sharp lip at the outer edge, visible ridging, and corrosion pitting that has begun to break through the braking surface. The rear discs should be checked with equal care, and the caliper sliders confirmed as moving freely, as a sticking caliper will accelerate the wear already noted by the inspector. The oil leak advisory warrants a visual inspection of the engine bay and undertray, with particular attention to wetness around the cam cover gasket, sump plug, and turbo oil feed lines if fitted, along with any fresh staining on the undertray itself. Given that the advisory specifically states the leak is not excessive, the priority is establishing whether it has progressed since the test. On a road test, listen for any change in engine note on cold start, watch the oil pressure warning light for any prolonged illumination, and monitor exhaust smoke on initial startup for blue tinge that might indicate oil reaching the combustion chamber. The nearside rear number plate lamp should be confirmed as functional across all lighting positions, and the offside rear tyre inspected for any slow pressure loss or repairable damage where the nail was previously identified, with the DOT date code checked to confirm sufficient remaining tread life across all four corners.
