2002 Mercedes C 2.1L Diesel · MM52 BUF

The most recent MOT on 13 August 2026 recorded a pass overall but flagged several advisories and a dangerous defect – the near‑side front tyre showing exposed ply or cords, which under MOT rules is a failure. The presence of repeated corrosion on both rear brake pipes, cut hand‑brake backplates and a scraping noise, together with earlier failures for binding service brakes, worn ball joints and insecure drum back‑plates, indicates a maintenance trend that is clearly deteriorating rather than stabilising. At 111,211 miles for a 2002 Mercedes C, the vehicle averages roughly 4,600 miles per year – a very low utilisation rate for a car of this age. Such modest mileage often reflects long periods of inactivity, which can be as damaging as high mileage because rubber compounds, seals and metal components age regardless of use. The low annual run‑off suggests that wear on consumables such as tyres, brake pads and clutch discs may be less than on a high‑mileage counterpart, but the calendar age raises concerns about tyre perishing, hose brittleness, battery degradation and corrosion in hidden areas. A prospective buyer should give the rear brake system immediate attention. Inspect both rear brake pipes for rust, pitting or thinning and consider replacing them, as corrosion can lead to sudden loss of hydraulic pressure. Examine the hand‑brake mechanism for the reported cutting and scraping – the backplates should be intact, the cables free of fraying and the parking‑brake lever should engage firmly without excessive play. The near‑side front tyre must be replaced straight away; exposed cords mean the tyre is unsafe and will fail catastrophically under load. While on the chassis, check the front ball‑joint dust cover and the lower suspension arm ball‑joint for excessive play or contamination, and verify the anti‑roll‑bar linkage bushes on both sides for wear; any looseness will manifest as clunking when cornering or over bumps. Test the service brakes for binding by applying firm, steady pressure – a binding front brake will feel stiff, may pull to one side and can cause premature wear of pads and discs. Also confirm that the front and rear brake drum back‑plates are securely fitted; missing or loose plates can cause uneven braking and rattles. Given the vehicle’s age and likely periods of standing, a thorough visual and tactile inspection of all rubber components is essential. Look for cracking or hardening of the drive belts, hoses, and the coolant expansion tank. Check the 12 V battery for sulphation and verify its cranking performance, as batteries over 20 years often lose capacity. Examine the tyre sidewalls for age‑related cracking even if tread depth appears adequate, and confirm that the tyre pressure holds steady. Finally, ensure that the engine oil, coolant, brake fluid and power‑steering fluid have been changed within the recommended intervals – fluids degrade with time and can cause internal corrosion or reduced braking efficiency if left stale. A full service history and any recent component replacements should be cross‑checked against the MOT records before committing to purchase.
