2013 Mercedes-Benz C 3.0L Diesel · HF63 ULB

The vehicle currently presents a stable and improving maintenance trajectory following a clean pass in January 2026 at 118,537 miles with no recorded defects. This recent success marks a significant recovery from the mechanical failures identified in late 2022. The transition from multiple serious defects to a consistent record of clean passes suggests the owner addressed the underlying issues effectively. The vehicle is roadworthy, though the history requires scrutiny regarding the emissions system repairs. Mileage accumulation has been consistent with the vehicle's age, averaging approximately 9,100 miles annually. Records show a notable increase in usage between September 2024 and January 2026, where the odometer advanced by over 18,000 miles. This higher intensity contrasts with the preceding period, which saw a more modest accumulation. The odometer progression appears logical and continuous without suspicious gaps, indicating the vehicle has remained in regular use rather than standing idle for extended periods. Prospective buyers must prioritise a detailed examination of the exhaust system. The December 2022 failure cited a tampered diesel particulate filter and excessive black smoke, requiring verification that a genuine, compliant unit has been fitted rather than a temporary repair. Suspension integrity also warrants attention, as the tester flagged corroded rear coil springs during the same failure. Although recent passes suggest these items were rectified, the previous binding rear brake and worn pads indicate the braking system underwent significant work. Inspecting the quality of these repairs is essential to ensure the vehicle remains reliable.
