2015 Mercedes-Benz B-Class 2.1L Diesel · 550 DPB

The vehicle achieved a clean pass on 22 November 2025 at 39,391 miles, confirming a stable mechanical condition following immediate rectification of a minor electrical fault. The failure recorded just one day prior on 21 November 2025 cited an inoperative rear registration plate lamp, a trivial defect that does not reflect underlying mechanical failure. This history indicates a generally improving maintenance trend, particularly when contrasted against the more severe structural and consumable failures noted in early 2023. With 39,391 miles recorded over approximately 11 years, this B-Class covers an exceptionally low annual average of roughly 3,581 miles. The odometer progression between the January 2023 test at 32,709 miles and the November 2025 entry shows an increase of only 6,682 miles. Such limited usage often suggests the vehicle may have spent extended periods stationary, a condition that can cause tyre perishing and fluid degradation despite the minimal mechanical wear. The most critical historical event occurred during the January 2023 test at 32,707 miles, where the nearside front tyre failed due to exposed ply cords, indicating a significant lapse in routine monitoring. At that same interval, the tester flagged front brake pads as wearing thin, which necessitated replacement to avoid future failure. A physical inspection should focus on checking all tyres for age-related cracking and ensuring the braking system has not seized due to infrequent use. The repeated advisories regarding registration plate lamps throughout 2024 and 2025 also suggest a potential issue with the rear light cluster wiring or bulb holders that requires verification.
