2018 Mercedes-Benz B-Class 1.5L Diesel · LP18 FGG

The 2018 Mercedes-Benz B-Class has demonstrated consistent roadworthiness over its MOT history, with no defects recorded across five tests spanning nearly four years. The most recent inspection, conducted on 24 June 2025 at 51,266 miles, confirms the vehicle passed without fail, reinforcing a stable maintenance trend. While the absence of advisories or recurring issues suggests the car has been reliably serviced, the gap between the 2023 and 2024 tests—nearly seven months—is slightly irregular, as MOTs are typically due annually. This interval does not inherently indicate neglect, but it warrants confirmation that the vehicle was not driven unsafely during that period. The mileage progression reveals a steady but moderate usage pattern, averaging around 6,400 miles annually, which aligns with typical expectations for a vehicle of this age. The largest jump occurred between the 2022 and 2023 tests, where mileage increased by 1,891 miles in just five months, suggesting either intensive use or a period of consistent driving. The earlier 2022 test at 17,246 miles, however, shows an unusually low mileage for a car nearly two years old, implying prolonged storage or limited use. This inconsistency could point to variable ownership or extended periods off the road, which may have affected certain components like tyres, suspension, or battery health. Given the clean MOT record, the primary focus for an in-person inspection should centre on high-wear items that are not always captured in a standard test. The suspension—particularly the rear coil springs and bushes—should be examined for uneven sagging or excessive play, as this class of vehicle is prone to bush deterioration over time. Brake discs and calipers, especially the rear, should be checked for uneven wear or binding, despite no recorded faults, given the mileage accumulation. Corrosion around wheel arches, sills, and the subframe is another critical area; while not flagged in past tests, the vehicle’s age and exposure history should be considered. Finally, verify the condition of the exhaust system for leaks or damage, as catalytic converter efficiency is not always visually apparent but can impact emissions and performance. A thorough check of the battery and alternator is also advisable, given the irregular MOT intervals.
