2017 Mercedes-Benz A-Class 1.5L Diesel · SS07 AVA

The most recent MOT test, conducted on 2026-03-19, resulted in a passing outcome, though it included several advisories that warrant careful attention. Despite the earlier failures in 2025 and 2024, the overall maintenance trend appears to be stabilising, with no major structural or safety-critical defects reported since the 2024 test. However, the recurring advisories on tyre wear, particularly the nearside rear outer tyre showing signs of cracking or perishing and the offside front tyre nearing legal limits, suggest ongoing or persistent issues that should be monitored closely. The presence of a front coil spring fracture in 2025 indicates a significant mechanical failure that, while not immediately roadworthy, may have been addressed post-test, though the vehicle’s suspension system now requires heightened scrutiny for long-term reliability. The vehicle’s recorded mileage of 66,825 miles at the age of nine years represents a moderate annual usage rate of approximately 7,425 miles per year, which is within the expected range for a car of this class. This level of mileage does not inherently suggest excessive wear beyond typical expectations, though the gaps in testing—particularly the two-year interval between the 2023 and 2024 MOTs—could indicate periods of either light use or potential neglect. The absence of higher mileage figures in recent years may also imply that the owner has maintained a more conservative driving profile, but this should not be assumed without further inspection. The suspension and braking systems, however, have been subjected to wear from consistent use, and the coil spring failure in 2025 underscores the importance of verifying the integrity of all suspension components, including bushes, struts, and dampers, for both comfort and safety. To proceed with a thorough inspection, the prospective buyer should prioritise examining the tyres for the advisories noted, particularly the nearside rear outer tyre’s sidewall damage, which may indicate underlying structural stress or improper alignment. During a test drive, listen for irregular suspension noises such as clunks or rattles, which could signal worn suspension bushes or damaged coil springs, and check for uneven tyre wear patterns that may reveal misalignment or steering system issues. The offside front tyre’s exposure of cords or cords reaching the ply layer is a critical failure that must be rectified immediately, as it compromises traction and safety. Additionally, inspect the front and rear brake systems for signs of binding calipers, corrosion on discs, or excessive pad wear, as the 2024 and 2023 MOTs highlighted thin pads and potential brake shudder, which could worsen with continued use. Verify the washer fluid system is operational and refill it to prevent windscreen integrity issues, which have been a recurring major defect. Beyond the mechanical checks, the buyer should also assess the vehicle’s standing condition for corrosion, particularly on the undercarriage, wheel arches, and brake components, as prolonged exposure to moisture can accelerate wear. Given the vehicle’s age, inspect the tyre sidewalls for signs of perishing or cracking, which can compromise structural integrity and safety, especially if the tyres have been stored for extended periods. Check the 12V battery for signs of weakness or failure, as older vehicles may develop poor electrical systems due to age-related battery degradation. Finally, verify the service history for fluid servicing, particularly the brake fluid, coolant, and transmission fluid, as these fluids degrade over time and should be replaced according to the manufacturer’s recommendations—typically every 60,000 to 100,000 miles or every two years, whichever comes first. A thorough inspection of the exhaust system for leaks or emissions-related issues, though not directly tied to the MOT history, is also advisable, as the A-Class may have experienced wear in catalytic converters or mufflers over its service life.
