2010 Mercedes-Benz B-Class 1.5L Petrol · KP10 TKT

The 2010 Mercedes-Benz B-Class holds a valid MOT certificate issued on 30 May 2026, yet the maintenance trend is worsening. The most recent test at 91,938 miles saw the vehicle initially fail due to an offside front tyre with tread depth below the minimum 1.6mm legal requirement and a severely deteriorated nearside front outer constant velocity boot. The tester also flagged a defective rear wiper blade. Passing the retest on the same day implies the tyre was replaced and the CV boot was renewed, though the severe deterioration of the boot prior to failure suggests previous owners neglected drivetrain servicing. Accumulating 91,938 miles over sixteen years equates to roughly 5,746 miles annually, indicating exceptionally light use. The mileage progression is remarkably consistent, showing steady increments of approximately 5,000 to 5,800 miles between the May tests from 2023 to 2026. No significant gaps or sudden spikes in accumulation appear in the record, ruling out prolonged periods of dormancy or sudden high-mileage runs. Low mileage typically preserves structural components, though infrequent use can lead to perishable items like rubber tyres and boots degrading through age rather than wear. A physical inspection must closely evaluate the undercarriage for corrosion, given the advisory for corroded rear fuel pipes recorded at 86,871 miles in May 2025. The 2024 test at 81,064 miles revealed slight play in the offside front suspension arm ball joint, alongside worn front inner brake pads and scored front discs. These mechanical wear points suggest routine servicing was delayed. The recurring tyre advisories, from perishing in 2025 to tread depth failure in 2026, indicate age-related rubber degradation rather than aggressive driving. Examine the nearside front outer CV joint for any signs of grease ingress or knocking, and verify the structural integrity of the underside, as corrosion and worn suspension components pose greater long-term risks than minor consumable wear.
