2018 Mercedes-Benz A-Class 1.5L Diesel · SR68 HLC

The vehicle’s most recent MOT tests, conducted on 9 December 2025 at 63,245 miles, reveal a concerning pattern of repeated failures despite no recorded defects on the pass tests. This inconsistency—where the same mileage and date appear for both pass and fail entries—suggests either a technical error in the DVSA system or, more likely, that the vehicle was tested twice under identical conditions, with the first test failing on criteria not documented in the public record. The absence of advisories or defects on the 2023 and 2024 tests implies that if there were underlying issues, they either resolved themselves or were not severe enough to trigger a fail until the most recent cycle. Buyers should treat this anomaly with caution, as it may indicate a history of unresolved mechanical concerns or a lack of transparency in previous ownership. The mileage progression shows a steady accumulation of approximately 7,900 miles annually, which aligns with typical usage for a vehicle of this age. There are no significant gaps or abrupt spikes in mileage between tests, suggesting consistent driving habits rather than periods of neglect or excessive wear. The most notable pattern is the identical mileage and date for the 2025 tests, which deviates from the usual annual testing cycle and warrants further investigation. Without additional service records, it is impossible to confirm whether this reflects genuine mechanical issues or administrative irregularities in the MOT process. Given the lack of documented defects in prior tests, the primary focus for an in-person inspection should centre on components prone to failure in this model at this mileage. The repeated testing at the same mileage in 2025 raises suspicion over brake system integrity—particularly the rear brakes, which are commonly overlooked in MOT failures for this class of vehicle. Suspension bushes and coil springs should be examined for excessive wear or corrosion, as these often degrade gradually and may not have been severe enough to fail previous tests. Additionally, the exhaust system and emissions controls should be checked for leaks or binding conditions, as these frequently trigger advisory notes or failures in Mercedes-Benz models. Structural corrosion, particularly around wheel arches and underbody panels, should also be assessed, as this is a critical long-term risk for vehicles of this age.
