2015 Mercedes-Benz Sprinter 2.1L Diesel · M546 ARK

The most recent MOT test on 2025-12-04 confirms the vehicle passed without recorded defects, though the history reveals a pattern of irregular testing rather than mechanical instability. The two consecutive failures in late 2024 and 2025—both without specific faults logged—suggest either administrative oversight or a deliberate attempt to avoid prolonged off-roadworthiness. The last successful test in October 2023 was followed by a 12-month gap before the first failure, indicating no clear trend of worsening mechanical issues. However, the absence of defect details in failures raises caution; minor faults may have been overlooked or corrected privately without official record. The vehicle’s mileage of 126,594 miles over approximately 11 years equates to around 11,509 miles annually, which aligns with typical usage for its age. There are no abrupt spikes or prolonged inactivity periods between tests, though the 2024 failures occurred just six days apart, suggesting either rapid wear or a temporary lapse in maintenance. The lack of mileage gaps larger than a year also implies consistent use rather than prolonged storage, which could mitigate some corrosion risks. Given the sparse MOT record, a buyer should prioritise an independent inspection of high-wear components not explicitly tested under MOT standards. Focus on the suspension—particularly rear coil springs and bushes—given the Sprinter’s tendency for bush deterioration over 100,000 miles. Binding brake calipers or uneven brake disc wear could explain the repeated failures, so verify hydraulic system integrity and rear brake flexibility. Structural integrity, especially around wheel arches and sills, should be checked for corrosion, as the Sprinter’s van body is prone to rust progression over time. Document any previous repairs or modifications, as the lack of defect specifics in failures may mask underlying issues.
