2015 BMW X4 3.0L Diesel · MH65 GKG

The 2015 BMW X4 presents a generally stable maintenance profile, passing every recorded MOT since at least December 2021. The most recent test on 12 December 2025 at 76,517 miles recorded no failures, though both front brake discs were flagged as worn, pitted, or scored. While this advisory has appeared in three consecutive tests, the condition has not deteriorated to a dangerous level, suggesting the discs have been in gradual decline rather than suffering a sudden mechanical failure. The vehicle appears to have been kept in a roadworthy state, with no dangerous or major defects recorded across the five-year window. The mileage progression tells a consistent story. Between December 2021 at 41,230 miles and December 2025 at 76,517 miles, the car covered roughly 35,287 miles in four years, averaging around 8,800 miles annually. That is slightly above the car's lifetime average of approximately 6,956 miles per year, indicating the current or most recent keeper has been using the vehicle more intensively. There are no suspicious gaps in the annual test record, and the mileage increments between tests align with regular use rather than long periods of dormancy or sudden high-mileage jumps. The recurring theme across the MOT history is front brake disc wear. Both nearside and offside front discs have been flagged in 2024 and 2025, and the 2022 test noted all four discs as worn. A buyer should inspect the front disc thickness and condition in person, checking for lipping, scoring depth, and whether the pads have been replaced more recently than the discs. The 2022 advisory regarding deteriorated front lower arm inner bushes on the nearside also warrants a close visual check, as worn suspension bushes can cause uneven tyre wear and vague steering. The front tyres were flagged as worn on both inner and outer edges in 2023, which is consistent with bush wear or misalignment, so any buyer should examine current tyre wear patterns carefully. Beyond the flagged items, the windscreen chips noted in 2023 and 2024 should be inspected to confirm they have not spread or been repaired, as stone chips on BMWs with advanced driver assistance systems can affect camera calibration. Given the car's age and mileage, a thorough underbody inspection for corrosion, particularly around suspension mounting points and subframes, would be prudent. The exhaust and DPF system should also be checked for smoke or fault codes, as no emissions-related advisories have appeared but the vehicle's age makes carbon buildup and sensor degradation realistic concerns.
