2021 Mercedes-Benz Citan 109 Pure CDI 1.5L Diesel · NG21 CKK

The Citan presents a stable and currently sound roadworthiness profile following its most recent MOT on 4 March 2026 at 67,301 miles, where it passed with zero defects. That clean result is particularly significant because it followed a failure just two days prior on 2 March 2026 at 67,288 miles, where the tester flagged rear brake pads below 1.5 mm and an engine malfunction indicator lamp fault. Both defects were evidently rectified before the retest, suggesting the previous owner addressed the issues promptly rather than deferring them. The maintenance trend is therefore improving, with the vehicle moving from an active fault state to a fully compliant one within a matter of days. The mileage accumulation tells a clear story of sustained high use. Covering roughly 24,000 miles between the July 2024 test at 43,014 miles and the March 2026 test at 67,301 miles equates to approximately 13,500 miles per year, which is well above the UK average for a light commercial vehicle of this age. The 14-month gap between the July 2025 pass at 63,779 miles and the March 2026 test adds another 3,500 miles in that interval, confirming consistent rather than sporadic use. No anomalous mileage reversals or suspicious gaps appear in the record, so the odometer history reads as genuine and linear. The July 2025 test at 63,779 miles flagged two advisories worth noting. The nearside rear tyre was worn close to the legal limit and worn on an edge, indicating either prolonged underinflation, a misaligned axle, or a suspension geometry issue causing uneven camber wear. The nearside front track rod end ball joint also showed slight play, a classic symptom of steering component fatigue that tends to accelerate under high-mileage use. Although neither defect caused a failure, their co-occurrence on the same axle side suggests the front end and rear tyre wear may share a common root cause, possibly alignment or suspension bush degradation. A prospective buyer should have the front suspension, steering linkage, and wheel alignment inspected on a four-post lift, paying particular attention to the track rod ends, inner and outer CV joints, and the condition of the rear suspension bushes and dampers. The March 2026 failure on rear brake pads is a consumable wear item and not inherently alarming on a vehicle covering this mileage, but it does confirm the braking system is being worked hard. The buyer should verify the condition of the rear brake discs for scoring or lipping, check the handbrake mechanism for correct adjustment, and inspect the front brake pads and discs to gauge remaining service life. Given the high annual mileage, the exhaust after-treatment system, including the DPF and EGR circuit, also warrants a diagnostic scan to confirm the MIL fault was fully resolved and that no stored codes remain. Overall, the record reflects a well-used but recently compliant vehicle, and a thorough pre-purchase inspection focused on steering, brakes, and suspension geometry should give a buyer confidence in its mechanical integrity.
