2014 Mercedes-Benz B-Class 2.1L Diesel · ST64 NER

The defining mechanical story of this 2014 Mercedes-Benz B-Class is one of broadly consistent roadworthiness, with the only blemishes on its DVSA record being minor electrical faults related to the registration plate lamps. Across seven recorded MOT tests between 2020 and 2026, the vehicle has passed six times with no defects noted, including the most recent test on 3 April 2026 which returned a clean pass. The two failures that do appear, recorded in October 2021 and November 2024, were both attributed solely to inoperative registration plate lamp bulbs and were resolved quickly, as evidenced by the immediate subsequent passes on 26 November 2024 and the absence of any repeat defect on the 2025 and 2026 tests. There are no recorded advisories for corrosion, suspension wear, brake component degradation, exhaust integrity, tyre condition, or any other mechanical or structural item, which provides a reassuring baseline for the prospective buyer. The recorded mileage of 91,128 miles against a 12-year vehicle age equates to an annual accumulation of roughly 7,594 miles, which sits comfortably within the typical usage bracket for a family-oriented MPV of this era. There are no extended multi-year gaps in the testing history that would suggest prolonged periods off the road, with tests recorded consistently in 2020, twice in 2021, 2022, twice in late 2024, and again in 2025 and 2026. This continuity supports the inference that the vehicle has remained in regular service throughout the recorded period, although the absence of granular mileage figures on the MOT certificate itself means any year-on-year mileage progression cannot be precisely verified from the data provided. From a buyer inspection perspective, the MOT history is notably devoid of advisories, so a prospective purchaser must rely on physical examination rather than the test record to identify developing wear. Given the mileage and age, particular attention should be paid to the suspension system, specifically the front lower wishbones, anti-roll bar drop links, and top mounts, as these are known wear items on the B-Class platform and would not necessarily have been flagged at MOT level until the deterioration became pronounced. On a test drive, listen for clonking noises over speed humps or uneven road surfaces, feel for imprecise steering or wandering at motorway speeds, and check for uneven tyre wear which can betray worn bushes or alignment issues. The braking system and underbody should also be scrutinised closely, as the MOT record provides no insight into brake disc thickness, pad wear, or the condition of flexible brake hoses and underbody protection. Inspect the inner and outer faces of all four brake discs for lipping or scoring, check that the calipers release cleanly without binding, and examine the underside for any signs of fluid weeping from the power steering rack, gearbox selector seals, or engine sump. The previously recorded registration plate lamp failures, while trivial, do suggest that minor electrical maintenance items may have been deferred, so verifying that all exterior lighting, including the number plate, side repeaters, and reversing lamps, is functioning correctly at the time of viewing is advisable.
