2018 BMW X4 2.0L Diesel · PL67 JOJ

High annual mileage defines the mechanical picture on this 2018 BMW X4, with the odometer having already climbed past 139,440 miles and the MOT history showing only tyre-related advisories across eight recorded tests. Seven of those tests passed without any defects being recorded at all, including four consecutive passes in 2022, 2023, 2024 and 2025, while the only flagged items were edge-wear advisories on the nearside and offside rear tyres in early 2021 and then on the nearside front and nearside rear tyres at the most recent test on 7 August 2026. There are no recorded failures, no brake, suspension, exhaust or corrosion advisories, and no advisory concerning oil leaks, lighting, wipers or structural components across the entire documented history. Taken at face value, the MOT record shows a vehicle that has stayed within the legal pass thresholds on every occasion it has been presented, with the only repeat theme being front and rear tyre edge wear. Against an age of roughly eight years, the recorded annual mileage works out at approximately 17,430 miles per year, which is materially above average for a car of this type and age. The testing frequency has been fairly consistent, with passes logged in 2021, 2022, 2023 (twice), 2024, 2025 and 2026, suggesting the vehicle has been in regular rather than sporadic use, with no obvious long stationary periods during which corrosion, brake seizure or battery degradation would typically develop unseen. However, the elevated mileage means that mechanical wear items beyond tyres — particularly the suspension, braking and drivetrain consumables — will have accumulated significantly more stress than the MOT history alone can reveal, as the test only samples condition at a single point in time. Given the advisory history, a prospective buyer should pay particular attention to the tyres and the geometry that is producing the edge wear. On a test drive, listen for any humming or drone that changes with speed, which can indicate uneven carcass wear rather than simple tread depletion, and feel for steering pull to one side or a steering wheel that is not centred straight ahead, both of which point to misalignment of the front or rear axle. Inspect all four tyres for feathering on the tread blocks and check that the wear pattern is symmetrical across each axle, as repeated nearside edge wear on a BMW X4 can also be linked to worn front suspension bushes or weak top mount bearings allowing geometry to drift under load. Because the MOT does not measure remaining tread depth once a tyre is above the legal limit, the nearside front and nearside rear items noted as close to the legal limit in August 2026 may already require replacement. The braking system and underbody deserve close physical scrutiny given the high mileage even though no related advisories have been recorded. On a test drive from a cold start, apply the brakes firmly at low speed to feel for any judder through the pedal, which would suggest warped front or rear discs, and listen for any grinding, scraping or metallic squeal that points to pads running low or worn caliper guide pins. At walking pace with the windows down, pass each wheel in turn and listen for any scraping, clicking or rumbling from the hubs, which can indicate worn wheel bearings. With the vehicle raised on a ramp if possible, inspect the front lower control arms, tension struts and anti-roll bar drop links for perished or split bushes, check the rear trailing arms and subframe mounting points for any surface corrosion, and examine the flexible brake hoses and rigid brake pipes along their full length for corrosion, swelling or chafing. The diesel or petrol engine should also be checked for any signs of oil misting around the cam cover, valve cover gasket, and turbo oil feed pipes, and the coolant expansion tank and radiator should be inspected for staining that could indicate a slow leak, all of which are common wear points on a BMW X4 that has covered this level of distance.
