2009 Mercedes-Benz B-Class 1.5L Petrol · KS58 URE

Persistent mechanical neglect is clearly evident across this Mercedes-Benz B-Class test history, defined by multiple failures that frequently escalated to dangerous or major status before achieving a pass. On 2026-03-18, the vehicle initially failed its examination before securing a pass later the same day, carrying forward a cluster of unresolved defects including a minor exhaust leak, worn brake discs, corroded rear brake pipes masked by grease, and a severely deteriorated nearside front outer constant velocity boot recorded as a minor defect. This recurring pattern of similar advisories spanning multiple consecutive years indicates that underlying structural and braking components have experienced prolonged deterioration without definitive corrective intervention. Accumulating 89,038 miles over its 17-year lifespan equates to a modest average of roughly 5,238 miles per annum, indicating a low-usage profile that has not prevented substantial mechanical wear on consumables and exposed underbody components. The testing log reveals consistent annual sequencing without notable gaps in continuity, demonstrating that the vehicle has remained in regular service despite accumulating recurring structural and braking advisories rather than suffering from prolonged periods of inactivity. When conducting a static inspection and test drive, immediate attention must be directed toward the braking system and front drivetrain. Listen carefully for clicking, ticking, or snapping noises emanating from the front wheels while executing tight turns, which would confirm advanced failure of the nearside front constant velocity boot and its underlying joint. Inspect the rear brake pipes directly where they are coated in grease to evaluate the true extent of the metal corrosion beneath, and test the brake pedal feel for any sponginess or excessive travel that would indicate thinning friction material across the worn discs. Furthermore, examine the exhaust system along the center pipe joints to locate the source of the persistent gas leaks noted in recent tests, checking for rattling or low-frequency humming during acceleration. Verify that all exterior lighting components operate correctly, paying particular attention to headlamp alignment and rear fog lamp functionality, both of which have previously caused test failures. A thorough ramp inspection is strongly advised prior to purchase to assess the structural integrity of the underbody and ensure that no hazardous corrosion or unaddressed wear is concealed beneath protective shields or grease.
