2021 Mercedes-Benz Sprinter 314 Progressive CDI 2.1L Diesel · YK71 ESN

The vehicle is currently roadworthy, but the maintenance history reveals a recurring trend of braking system neglect. While the most recent test in August 2025 at 149,210 miles passed, the tester noted that the offside front service brake only just met the minimum requirements. This follows a failure in August 2024 where both nearside and offside front brakes were flagged as excessively binding. The persistence of these issues suggests that underlying mechanical faults are being treated symptomatically rather than fully rectified. The mileage accumulation is exceptionally high for a five-year-old vehicle, averaging approximately 30,000 miles per year. Between the August 2024 test at 114,400 miles and the August 2025 test at 149,210 miles, the van covered nearly 35,000 miles in a single year. This intensive high rate of use puts significant strain on drivetrain components, suspension bushings, and braking hardware, which accelerates the wear of consumable parts. A buyer must conduct a thorough inspection of the braking assembly to determine why the front calipers are seizing or if the slide pins are failing. The record shows pitted and scored rear brake discs from late 2024, which should be checked for excessive thinning or uneven wear patterns. Given the high mileage and the reported binding issues, an inspection should also evaluate the suspension geometry and coil springs for fatigue, as these components often suffer rapid degradation under constant heavy-duty use cycles.
