2005 Mercedes-Benz C 2.1L Diesel · FX55 OKK

The vehicle shows a fluctuating maintenance trend that has recently improved following a significant failure. The most recent test on 10 November 2025 at 173,501 miles resulted in a clean pass with no defects recorded. This follows a failed inspection just twelve days prior on 29 October 2025, where the tester identified a fractured nearside front coil spring, an inoperative offside rear parking brake, and a damaged anti-roll bar linkage dust cover. The successful pass suggests these specific mechanical failures were addressed promptly. The mileage accumulation appears consistent with a vehicle of this age, averaging approximately 8,262 miles per year over its 21-year lifespan. The record shows steady usage, with the mileage increasing from 80,553 in November 2014 to 173,501 in November 2025. There are no significant periods of long-term inactivity evident in the data, though the gap between the October 2024 and December 2022 tests suggests a period where the vehicle may have been off the road or the testing interval was not strictly followed. A prospective buyer should focus heavily on the vehicle's structural integrity and braking system. The history reveals a persistent pattern of corrosion, specifically regarding brake pipes and the rear axle. The December 2021 test flagged significant rear axle corrosion and a welded offside front wheel, which indicates past structural repairs or advanced degradation. While the 2024 test noted corroded brake pipes, the 2025 failure highlighted a substantial loss of parking brake efficiency. These recurring issues suggest that while consumables are being replaced, the underlying issue of environmental corrosion remains a long-term risk. Suspension components also require close scrutiny. The record shows repeated failures involving coil springs and anti-roll bar components, including a fractured nearside front spring in October 2025 and various worn bushes and linkages in 2018 and 2021. Given the age of the vehicle and the history of suspension wear, a thorough inspection of all bushings, ball joints, and spring seats is necessary to ensure no further component fatigue has occurred since the last successful MOT.
