2010 BMW Z4 2.5L Petrol · GL10 OKT

The 2010 BMW Z4 passed its most recent MOT on 4 September 2025 at 108,425 miles, but the record reveals a mixed maintenance picture rather than a clean bill of health. The car failed the previous day on 3 September 2025 with four defects, including brake pads worn below 1.5 mm on both rear sides, an inoperative headlamp levelling device, and a slightly distorted offside front wheel. That wheel distortion advisory carried over into the pass, meaning it was noted but not severe enough to cause a failure. The trend here is one of reactive rather than preventive upkeep. Critical safety items like brake pads were allowed to wear to the minimum legal thickness before replacement, and a headlamp levelling fault suggests electrical or suspension-height sensor issues were left unresolved for at least a day before retest. The maintenance pattern is neither clearly worsening nor improving. It sits in an inconsistent middle ground where faults are addressed just enough to pass rather than being caught early. The mileage accumulation tells a coherent story. Between the August 2023 test at 94,484 miles and the September 2024 test at 102,072 miles, the car covered 7,588 miles in roughly thirteen months. The following year, from September 2024 to September 2025, it added only 6,353 miles. This is broadly consistent with the vehicle's lifetime average of approximately 6,777 miles per year across sixteen years of use. There are no alarming gaps or sudden spikes in the recorded data. The annual intervals between tests appear regular, and the mileage progression supports a pattern of steady, moderate use rather than prolonged standing or aggressive high-mileage driving. A buyer inspecting this Z4 in person should focus on the rear braking system and front wheel integrity. The September 2025 failure recorded both rear brake pads below 1.5 mm, which indicates the rear calipers, discs, and pads need careful measurement for remaining life. Binding rear calipers or uneven disc wear could explain why the rear pads degraded faster than fronts. The persistent advisory for a slightly distorted offside front wheel warrants a close look at the rim for kerb damage or cracks, along with checking the tyre for uneven wear patterns. The inoperative headlamp levelling device, while resolved for the pass, points to a potential fault in the self-levelling suspension sensors or control module, so a static headlamp aim check and a test of the ride-height function are advisable. The 2024 failure flagged structural tyre damage including a bulge from internal separation on the nearside front, which raises questions about whether suspension components like bushes, coil springs, or dampers are contributing to abnormal tyre loading. A thorough underbody inspection for corrosion, particularly around suspension mounting points and subframes, is essential given the car's age. The tyre-related failures in 2024 suggest basic consumable checks were neglected, so verifying the condition of all four tyres, including sidewalls and tread depth, should be a priority before purchase.
