2009 Mercedes-Benz C 2.1L Diesel · WM09 HBO

The most recent MOT test, conducted on 2026-01-15, resulted in a clean pass with only three advisories—an oil leak of limited severity, minor cuts in the near-side and offside front tyres that do not reach ply or cords, and a slight play in the near-side front wheel bearing. This follows a pattern of fluctuating results over the past seven years, with a mix of failures and passes that suggest some recurring but manageable issues rather than a clear deterioration trend. The vehicle’s history shows periods of both passing and failing MOTs, particularly in areas like tyre integrity, wheel bearings, suspension components, and electrical systems, indicating that while the car has faced some maintenance challenges, it has not succumbed to catastrophic failure. The presence of multiple advisories—especially those related to wheel bearings and suspension ball joints—demands attention, but the absence of major failures in the latest test suggests that the vehicle remains roadworthy with prudent upkeep. The recorded mileage of 95,117 miles for a vehicle aged approximately 17 years represents a remarkably low annual usage rate of around 5,595 miles per year, which is far below the typical expectations for a car of this age and make. Such low mileage often correlates with prolonged periods of inactivity, particularly if the vehicle has been stored under adverse conditions or used sparingly for residential or leisure purposes. However, this usage profile can mask underlying wear and tear, as components like brakes, suspension, and fluids may degrade over time due to standing rather than active use. The combination of low mileage and age raises concerns about potential issues such as tyre sidewall perishing, corrosion from prolonged exposure to moisture, and the degradation of fluids like brake and differential fluids, which can harden or break down even without significant mileage accumulation. For a prospective buyer, the most critical areas to inspect during a physical examination and test drive are the suspension and wheel bearings, given the recurring advisories of slight play in the near-side front wheel bearing and offside front suspension arm ball joint. During a test drive, listen for unusual clunking or rattling noises from the front suspension, particularly when navigating bumps or sharp turns, as these may indicate further wear in the ball joints or bushings. Inspect the front wheels for uneven tyre wear patterns, which could suggest misalignment or suspension issues, and check for any signs of oil leakage around the wheel bearings or suspension components. The exposed ply in the near-side rear tyre from the 2024 MOT failure and the tread depth below legal limits in that tyre necessitate immediate replacement, as these are safety-critical defects. Additionally, verify that the brake system is functioning correctly, as the history of brake pipe corrosion and potential grease ingress could lead to reduced braking performance or even failure if not addressed. Beyond the immediate concerns, the vehicle’s low mileage history means the buyer should prioritise checks for age-related wear and tear that may not be evident from mileage alone. Examine the tyres for signs of sidewall cracking or perishing, which can compromise structural integrity and safety, especially if the vehicle has been stored in a damp or cold environment. Check the battery terminals for corrosion or loose connections, as standing vehicles can lead to battery drain or failure if not maintained. Inspect the exhaust system for signs of corrosion or structural weakness, particularly around the rear tyres where previous MOT failures were noted, and ensure the emissions system is functioning correctly, as the vehicle’s age may have led to fluid degradation in the catalytic converter or exhaust manifold. Finally, verify that the service history is up to date, particularly for fluid changes, as time-based servicing is critical for a vehicle of this age, even if mileage is low. The presence of multiple electrical faults from past MOTs also highlights the need to test all lights, indicators, and warning systems thoroughly to ensure compliance with current regulations.
