2016 Ford Grand C-MAX 1.5L Diesel · AC05 KOO

A recurring pattern of oil leakage and lighting irregularities defines the recent mechanical profile of this Ford Grand C-Max, with the most recent test on 11 March 2026 confirming a continued advisory for an oil leak. While the vehicle passed its latest inspection, it required significant remedial work just one day prior on 10 March 2026 following a failure due to incorrect headlamp aim on both sides and incompatible light sources. This recent failure suggests recent bulb or headlight unit replacements that were not correctly calibrated or fitted, marking a shift from the clean records seen in 2021, 2022, and 2023 towards a more frequent requirement for component attention. The vehicle has covered 134,647 miles over its ten-year lifespan, representing an average annual usage of approximately 13,465 miles. This level of mileage is relatively high for a vehicle of this age and implies a consistent usage pattern that subjects mechanical components to regular wear. In the context of the MOT history, this higher mileage correlates with the increased frequency of advisories regarding consumable items such as tyres and brake pads appearing in the 2024, 2025, and 2026 records. Such usage typically accelerates the degradation of suspension bushes, braking systems, and sealing components. Prospective buyers should pay close attention to the persistent oil leak advisories that have been noted since at least 2024. During a test drive, it is necessary to observe the engine bay for signs of fresh weeping and to check under the vehicle for any active dripping that could indicate a worsening seal or gasket failure. Given the history of headlamp failures regarding aim and compatibility, the lighting system should be thoroughly inspected to ensure the beams are correctly levelled and that no flickering or uneven illumination occurs, which could indicate electrical issues or poorly seated components. The recorded advisories for tyres worn close to the legal limit and brake pads wearing thin in 2025 indicate that the vehicle is approaching or has recently passed through several maintenance intervals for consumables. On a test drive, listen for any rhythmic knocking or clunking over bumps which might suggest worn suspension components, and feel for any pulsation through the brake pedal or pulling to one side when braking, which could indicate uneven pad wear or binding calipers. The history of tyre wear on the edges also warrants an inspection of the wheel alignment to ensure the steering geometry is within specification.
