The most recent MOT was on 2025-08-13 — just over 10 months ago — and the vehicle passed with a serious defect: the offside front outer CV boot is severely deteriorated. This is not a minor advisory; it’s a failure-level issue under MOT regulation 6.1.7(g)(i), meaning it poses a real risk of grease loss, contamination, and eventual CV joint failure. This same defect appeared identically on the 2024-08-01 MOT at 52,904 miles — so it has persisted for at least two full annual tests, across 13,220 miles of driving. That indicates the boot has not been replaced or repaired in that time, and the condition is stable only in the sense that it hasn’t yet caused a failure — but it is actively worsening with use. A severely deteriorated CV boot will continue to degrade, increasing the chance of sudden joint seizure or axle lock-up, especially under load or cornering. The 2023 MOT history shows a clean pass followed by an immediate fail on the same day — due solely to ineffective wipers on both sides. That’s a trivial, low-risk issue easily fixed, and it doesn’t recur. Otherwise, the record is sparse: only four MOTs since registration, with no other defects logged beyond the CV boot and wipers. At 66,124 miles and just under six years old, the average is ~11,021 miles per year — broadly typical for a light commercial vehicle. It doesn’t suggest excessive hard use, nor unusually low mileage that might hint at long periods of inactivity (which can cause rubber perishing, brake seizing, or fluid stagnation).
