2020 Mercedes-Benz Citan 109 Pure CDI 1.5L Diesel · PK20 WML

The 2020 Mercedes-Benz Citan 109 Pure CDI presents a stable and improving maintenance trend, culminating in a clean pass on 16 July 2025 at 60,035 miles with zero defects recorded. That result marks a clear step forward from the 2023 test cycle, when the vehicle failed on 6 June 2023 at 46,262 miles for multiple lighting and brake pad defects. The same tester flagged the offside rear inner brake pad wearing thin during the retest pass later that day, indicating the issue was caught early rather than left to escalate. No further advisories or failures have appeared since, suggesting the last two owners addressed the defects promptly and have maintained the vehicle to a reasonable standard. The mileage accumulation of roughly 10,006 miles per year sits squarely within the typical range for a light commercial van of this age. The 2,841-mile gap between the June 2023 test at 46,262 miles and the May 2024 test at 57,194 miles represents a noticeable jump of 10,932 miles in under twelve months, pointing to a period of heavier use or a return to regular service after potentially lighter running. The recorded mileage then plateaued between May 2024 and July 2025, with no further test recorded, meaning the van may have stood idle or covered very little distance during that fourteen-month window. Buyers should verify whether that gap reflects genuine low use or a missed test. The 2023 failure pattern centred on rear braking and lighting components, both consumable items on a working van. The offside rear inner pad wearing thin is a routine wear point on light commercials that carry uneven loads, and the stop lamp faults were electrical rather than structural. No suspension, steering, corrosion, or emissions defects have ever appeared on the record, which is encouraging for a six-year-old van. A buyer should still inspect the rear brake discs and calipers for uneven wear or binding, given the earlier pad advisory, and check all rear lamp units for water ingress or intermittent function. The underbody and sills deserve a close look for corrosion, as the Citan shares its platform with the Renault Kangoo and is prone to surface rust in salted regions. The long idle stretch before the 2025 test also warrants a fluid and belt inspection to confirm nothing has deteriorated from standing.
