2009 Mercedes-Benz C 1.8L Petrol · SA09 CYY

The vehicle's most recent MOT test, conducted on 17 May 2023, resulted in a clean pass with no advisories or defects recorded, which represents a positive and reassuring outcome. The preceding test in June 2022 was also passed without advisories, suggesting a stable maintenance trajectory over the short term. However, the 2022 pass came immediately after a failed test on the previous day, where the vehicle was found with multiple major defects including an excessively worn anti-roll bar ball joint, a front wheel bearing with excessive play, and a parking brake that failed to meet minimum efficiency requirements. Although the immediate rectification of these issues is implied by the subsequent pass, the clustered nature of these front suspension and brake-related defects indicates that attention should be directed toward the condition of the front subframe mounting points, control arm geometry, and the integrity of the handbrake mechanism, as wear in these areas can be progressive. With a recorded mileage of 122,001 miles over approximately seventeen years, the vehicle has accumulated an annual average of around 7,177 miles, which is broadly typical for its age and suggests regular but moderate use. The MOT history does not reveal any extended periods of standing or sudden spikes in mileage, indicating consistent utilisation. This kind of usage pattern tends to keep mechanical components in reasonable working order, particularly the engine, drivetrain, and braking system, as components are exercised regularly rather than suffering the seizing and fluid degradation associated with prolonged inactivity. Despite the clean recent results, the advisory history warrants careful physical inspection prior to purchase. The repeated advisories concerning front brake disc wear on both the nearside and offside in 2020 and again in 2021 suggest that the discs may now be approaching minimum thickness, and a prospective buyer should measure disc run-out and thickness, listening on test drive for any shudder under braking or scraping indicative of worn pads contacting the discs. The dangerous tyre defect recorded in 2021 also highlights the importance of inspecting the sidewalls of all four tyres for perishing or cracking, particularly given the vehicle's age, as older rubber compounds degrade independently of tread depth. Furthermore, the recurring windscreen washer and wiper advisories from 2020 suggest that electrical ancillaries may be subject to age-related deterioration, so a thorough check of all washers, wipers, interior electronics, and lighting is advisable. Beyond the documented MOT findings, a seventeen-year-old Mercedes-Benz of this mileage requires diligent inspection of time-served components. The 12V battery should be tested for cranking capacity, as units of this age frequently struggle in colder conditions and can lead to electrical faults. Brake fluid, coolant, and automatic transmission fluid all degrade over calendar years irrespective of mileage, and verifying the service history for evidence of recent fluid changes is essential; neglected coolant in particular can lead to corrosion within the cooling system and water pump failure. The exhaust system, including the catalyst and rear silencer, should be examined for corrosion and blowing joints, as original Mercedes exhausts of this era are known to suffer from internal rot. Finally, a careful test drive should be conducted over varied road surfaces to detect any clonks from the front suspension, particularly as the anti-roll bar joints previously exhibited wear, and any knocking or vibration from the rear axle, alongside verification that the air conditioning system functions, as climate control repairs on this model can prove costly if the compressor or condenser has failed.
