2021 Mercedes-Benz Sprinter 314 Progressive CDI 2.1L Diesel · KR21 ACV

The most recent MOT on 2025-09-04 recorded two key issues: front brake discs showing wear, pitting, or scoring (not seriously weakened) and severely deteriorated front outer drive shaft constant velocity (CV) boots on both sides. The registration plate was also noted as deteriorated but not misreadable. These findings align with a pattern of recurring mechanical concerns. A prior MOT from 2024-07-03 revealed similar issues: front brake discs in a worn state, deteriorated CV boots, and front brake pads wearing thin. The repetition of brake disc and CV boot defects across two MOTs suggests a persistent risk of further deterioration. While the 2025 MOT did not mention brake pads, the continued presence of CV boot damage indicates unresolved or ongoing wear. The trend shows no clear improvement, but the severity of defects remains within acceptable limits for a passing MOT. However, the recurrence of the same issues implies that the vehicle’s components are experiencing sustained stress, likely due to higher-than-average mileage (approximately 11,829 miles per year). This could accelerate wear on brakes, suspension, and drivetrain elements, particularly if the vehicle has been used intensively or in demanding conditions. Mileage of 59,145 miles for a 5-year-old vehicle is slightly above the typical annual average, which may indicate heavier usage or frequent short trips.
