2021 Mercedes-Benz Citan 109 Pure CDI 1.5L Diesel · LL21 CFM

The most recent DVSA MOT test for this 2021 Mercedes-Benz Citan 109 Pure CDI took place on 12 May 2025, with the vehicle achieving a pass. However, it is worth noting that a failure was also recorded on the same date immediately prior to the pass, which is a normal occurrence when a vehicle is presented, fails on certain items, is repaired on site or shortly after, and then re-presented for retest within the permitted window. No specific defects or advisories were recorded against either the failure or the pass entry. The previous test cycle shows a similar pattern, with a pass on 30 May 2024 preceded by a failure on 28 May 2024, again with no defects listed. While the absence of recorded advisories is reassuring on the surface, the dual fail-then-pass entries suggest there have been issues addressed each year, even if they were minor enough not to be formally documented. Overall, the maintenance trend appears stable but borderline, warranting further physical verification rather than relying solely on the MOT certificate. With 74,738 miles recorded on a five-year-old vehicle, this Citan is averaging approximately 14,948 miles per year, which is notably high for its class and age. Commercial-derived vehicles such as the Citan are often designed to withstand such usage, but the cumulative wear on drivetrain, braking, and suspension components will be more advanced than in a lower-mileage example. Continuous high mileage typically accelerates wear on dual-mass flywheels, clutch assemblies, turbochargers, diesel particulate filters, and engine mounts, particularly in stop-start urban or delivery cycles. There are no significant mileage gaps in the recorded history, suggesting the vehicle has been in regular service rather than left standing for prolonged periods. This consistent usage is generally favourable for preventing corrosion from inactivity, but it places greater emphasis on verifying recent servicing of wear-prone components. Given the clean defect record, a prospective buyer should focus on age and mileage-appropriate items that may not be captured during an MOT test but remain critical to long-term reliability. Tyres should be carefully inspected for uneven wear patterns, particularly on the inner edges, which can indicate worn suspension bushes, tie rod ends, or tracking misalignment. Although the vehicle has been in regular use, brake discs may still exhibit lipping or surface corrosion, and caliper slide pins should be checked for seizing. The 12V battery should be load-tested, as diesel vehicles with frequent short journeys place heavy demand on batteries, and a failing battery can cause cascade electrical faults. Additionally, age-related deterioration should not be overlooked, including perished coolant hoses, brittle vacuum lines, and any signs of fluid leakage around the engine, gearbox, and steering rack. A thorough test drive should be conducted to identify symptoms that a static inspection might miss. Listen for any clonking or knocking from the front suspension over speed humps, which could signify worn anti-roll bar drop links, top mounts, or coil springs. Pay attention to brake feel, looking for sponginess, pulling to one side, or excessive pedal travel, which could point to worn calipers or degraded fluid requiring a brake fluid flush regardless of recent service records. On acceleration, monitor for any hesitation, turbo whistle anomalies, or excessive black smoke, all of which could indicate injector wear or DPF issues common to higher-mileage diesel vans. Finally, verify that the vehicle has a fully stamped service book and request evidence of cambelt or timing chain replacement intervals, as well as recent diesel particulate filter regeneration history, to ensure the maintenance schedule has been adhered to in line with this demanding usage profile.
