2017 BMW X4 2.0L Diesel · YJ17 PEF

The most recent MOT was on 2025-08-27 — just under 10 months ago — and it passed cleanly at 45,391 miles. That’s reassuring, but it followed a failure only four days earlier for a serious tyre defect: a deep cut on the offside rear that exposed the ply or cords. That failure was not a minor advisory — it was an outright fail under category 5.2.3(d)(i), meaning the tyre was unsafe to drive on. There is no recurring mechanical pattern in this MOT history. All previous tests from 2022 to 2024 passed with zero defects recorded. The sole failure was isolated to a single tyre — no suspension, brake, steering, or lighting issues appear anywhere in the record. The condition trend is stable overall, with one clear exception: the tyre failure suggests either sudden damage (e.g., road hazard) or delayed attention after wear progressed unnoticed. Since the pass four days later confirms the issue was resolved — almost certainly by replacing the tyre — there’s no evidence of worsening mechanical health. But the gap between the fail and pass hints the problem may have been present for some time before detection. At 45,391 miles over nine years, the car averages just over 5,000 miles per year — well below typical UK usage.
