2017 Mercedes-Benz A-Class 1.5L Diesel · CF17 CFU

The most recent MOT inspection on 12 June 2026 resulted in a pass, but the vehicle shows a concerning trend of increasing advisories regarding the braking system and tyre condition. While the car has maintained a consistent pass record since 2020, the frequency and nature of the recorded defects suggest that the vehicle is entering a phase of age-related degradation. The transition from a clean MOT in 2024 to multiple advisories in 2025 and 2026 indicates that maintenance requirements are escalating, particularly concerning the integrity of the braking lines and the rubber components of the tyres. With a recorded mileage of 48,207 miles over approximately nine years, this Mercedes-Benz A-Class has averaged roughly 5,356 miles per year. This is significantly lower than the UK national average, suggesting the vehicle has been used sparingly or has spent considerable periods stationary. While low mileage generally implies less mechanical wear on the engine and drivetrain, it introduces specific risks associated with long periods of standing. Such usage patterns can lead to accelerated degradation of rubber seals, the perishing of tyre sidewalls, and the buildup of corrosion on brake discs and hydraulic lines due to lack of regular cleaning and thermal cycling. A prospective buyer should pay close attention to the recurring advisories regarding the rear tyres, which have been noted for cracking and perishing in both 2025 and 2026. This is a classic symptom of age-related rubber degradation, often caused by UV exposure or long periods of inactivity rather than tread wear. During a test drive, you should inspect the tyre sidewalls for any deep fissures and check the tread depth, but more importantly, listen for increased road noise which may indicate the rubber has hardened. Furthermore, the advisory regarding the offside rear brake pipe being corroded and obscured by grease is a significant point of concern. The grease may have been applied to mask the extent of the corrosion, so you must ensure the brake lines are inspected by a technician to confirm they are not nearing a structural failure that could lead to hydraulic fluid loss. The history of a failed wheel bearing in 2024 and various advisories regarding pitted or scored brake discs suggests that the braking and hub components are subject to environmental corrosion. On your test drive, listen for any rhythmic humming or grinding noises from the wheel arches, which would indicate a failing bearing, and feel for any pulsations or vibrations through the brake pedal, which could signal warped or heavily corroded discs. Given the low annual mileage, I also recommend verifying the service history for calendar-based maintenance, such as brake fluid changes and oil services, as these are critical when a vehicle is not driven frequently enough to maintain optimal component cleanliness and fluid chemistry.
