2015 Mercedes-Benz Auto-Sleepers 2.1L Diesel · DT11 TAP

The vehicle remains in a roadworthy condition, showing a stable maintenance trend despite its low usage. The most recent test in September 2025 at 20,586 miles resulted in a pass despite the front brake discs being pitted and scored. This issue is a recurrence of a fault seen in the 2021 test at 14,103 miles, suggesting the components are prone to surface corrosion during periods of inactivity. The mileage profile is exceptionally low for an eleven-year-old vehicle, averaging approximately 1,871 miles per year. Between September 2022 and September 2025, the vehicle covered only 3,518 miles, indicating a consistent pattern of low-intensity operation. This low rate of travel suggests the motorhome sits for long durations at a time. While this preserves mechanical wear on the engine and drivetrain components, it often leads to the degradation of rubber-based parts and the oxidation of metal surfaces due to lack of use. A buyer should focus specifically on the braking system during a physical inspection. The recurring pitting and scoring on both the nearside and offside front brake discs in 2021 and again in 2025 indicates that the discs are developing surface-rust while stationary. You must check the brake pad thickness for uneven wear and ensure the calipers are not seized from inactivity. Additionally, given the low mileage and age, an inspection of the suspension bushes, hoses, and tyres for dry rot is essential, as these components often age faster than they wear out on low-mile vehicles.
