2008 Mercedes C 2.1L Diesel · AO58 HPK

The vehicle holds a pass in its most recent MOT conducted on 3 October 2024 at 250,471 miles, yet the maintenance trend is not reassuring. That test carried four advisories including corroded front brake pipes, worn front inner brake discs, and a worn offside rear tyre. Repeated appearances of corroded brake pipes and worn front brake discs across the 2022, 2023, and 2024 records indicate a chronic issue rather than a one-off repair. The car failed its first 2023 test on the same day as its pass, with a missing anti-roll bar linkage dust cover and play in the nearside steering rack inner joint. Suspension and steering wear have persisted across multiple years, suggesting components are operating at or beyond their service life. Mileage accumulation tells a clear story of sustained high use. Between the November 2022 test at 233,080 miles and the November 2023 test at 239,812 miles, the car covered 6,732 miles in twelve months. From November 2023 to October 2024, it added 10,659 miles, a notable acceleration. Annual averages sit around 13,915 miles, well above typical for an eighteen-year-old C-Class. The MOT record is continuous with no significant gaps, so there is no evidence of long-term storage masking the true condition. High mileage at this age places sustained stress on drivetrain mounts, suspension bushes, cooling system components, and exhaust fittings. Buyers should focus their physical inspection on the front brake pipe runs, particularly where advisories repeatedly note corrosion under grease or other material. This often conceals pitting that compromises structural integrity under pressure. Front brake discs have been flagged as worn in three consecutive tests, so expect near-minimal thickness or lipping. The nearside steering rack inner joint play noted in 2023 warrants a check for clunking over uneven surfaces and uneven tyre wear. Suspension joints and anti-roll bar linkages have appeared in failed and advisory items since 2022; a thorough check of ball joint boots, wishbone bushes, and drop links is essential. The rear brake pads were below 1.5 mm in 2022, and while later tests do not repeat this, rear braking components on a car this mileage deserve close measurement. Beyond the flagged items, examine the subframe and inner wing arches for corrosion, as eighteen-year-old Mercedes of this mileage frequently develop structural rust in load-bearing areas. Check the exhaust system for leaks or deterioration, and verify that all lamp lenses and fog lamp glasses are intact, given the repeated minor lighting advisories. The tyre wear pattern noted on the offside rear in 2024 suggests possible tracking or alignment drift. A compression test and inspection of engine mounts would be prudent given the high mileage, as these are common failure points not always visible in MOT data.
