2013 Mercedes-Benz Citan 1.5L Diesel · RV63 SYF

The Mercedes-Benz Citan’s MOT history presents a concerning pattern of repeated failures over the past year, despite no recorded defects in any test. The most recent entry, a pass on 28 July 2025 at 137,539 miles, was preceded by two consecutive fails in June 2025—both without any faults logged. This suggests the vehicle was not meeting basic roadworthiness criteria, yet no mechanical issues were formally documented. The earlier 2024 tests, both passed and failed on the same date (29 May 2024) at 135,024 miles, further indicate a history of intermittent compliance rather than progressive deterioration. The absence of defects in any test is unusual for a vehicle of this age and mileage, implying either undetected faults or an unusually lenient testing process. The trend is neither stable nor improving; instead, it reflects a vehicle that has repeatedly slipped through without clear evidence of systematic maintenance or repair. The mileage accumulation of 137,539 miles over 13 years—roughly 10,580 miles annually—aligns with typical usage for a commercial or fleet vehicle of this age. However, the clustering of tests in 2024 and 2025, particularly the back-to-back fails in mid-2025, raises questions about why the vehicle was retested so frequently. The mileage gap between the 2024 and 2025 tests (around 2,500 miles over nearly a year) suggests either minimal use or, more likely, a deliberate delay in presenting the vehicle for inspection. The lack of mileage progression during this period, combined with the repeated failures, implies the vehicle may have been stored or used sparingly while unresolved issues persisted. Given the absence of documented defects, a buyer should prioritise a thorough mechanical inspection, particularly focusing on components prone to undetected wear or failure in older diesel vans. Suspension components—such as coil springs, anti-roll bars, and bushings—should be checked for fatigue or corrosion, especially if the vehicle has spent time in damp or salty conditions. Brake systems, including calipers, discs, and hydraulic lines, must be assessed for binding or uneven wear, as the repeated fails without recorded faults could mask underlying brake inefficiency. Structural integrity, particularly around wheel arches, sills, and suspension mounts, should be scrutinised for hidden corrosion or stress cracks, common in vehicles of this age. Additionally, the exhaust system and emissions controls may warrant closer inspection, as older diesel engines often develop subtle leaks or sensor failures that evade MOT scrutiny. The lack of recorded defects in any test is atypical and warrants caution. While the vehicle may appear mechanically sound on paper, the pattern of repeated failures without explanation suggests either evasion of testing standards or unresolved issues that could escalate. A pre-purchase inspection by a qualified Mercedes-Benz technician is strongly advised to verify structural, brake, and suspension integrity before commitment.
