2015 Mazda 6 2.2L Diesel · SM15 OCP

The vehicle currently holds a valid MOT certificate issued on 18 March 2026 at 119,212 miles, following a failure just two days prior on 16 March 2026. That failure revealed a fractured offside rear coil spring, excessively worn nearside front suspension arm ball joint, non-functional front position lamps, and front tyres worn to the legal limit. The coil spring fracture and ball joint wear are serious mechanical defects that directly affect structural integrity and safe handling. Their repair before the pass indicates the immediate faults were addressed, but the pass certificate itself carries an advisory for corrosion affecting front and rear suspension components, a condition that was already noted in the March 2025 test. This suggests the corrosion is progressive and has not been arrested. Mileage accumulation tells a clear story of changing usage patterns. Between the May 2024 test at 99,059 miles and the January 2025 test at 106,737 miles, the vehicle covered 7,678 miles in roughly eight months, a moderate pace. However, from January 2025 to March 2026, the car added 12,475 miles in fourteen months, averaging roughly 890 miles per month, a notable step up in usage. The recorded mileage of 119,212 at roughly 10,837 miles per year over eleven years sits within typical parameters for its age, with no suspicious gaps or implausible jumps in the data. The recurring fault pattern centres on suspension and braking components, with tyre wear appearing consistently across multiple tests. Both front and rear tyres were flagged as worn close to the legal limit in May 2024, and the March 2026 failure repeated that finding on the front axle. This repeated pattern suggests the vehicle may suffer from persistent alignment issues, worn suspension geometry, or simply that previous owners deferred tyre replacements until the legal minimum. The fractured offside rear coil spring in March 2026 is particularly significant, as it points to a sudden failure in a critical load-bearing component. Combined with the advisory for corrosion across front and rear suspension components noted in both 2025 and 2026, a prospective buyer should arrange a thorough inspection of all suspension mounting points, wishbones, trailing arms, and subframe mounting areas for advanced corrosion. The rear brake pipes were flagged as excessively corroded in May 2024 and subsequently repaired, but any buyer should verify the current condition of all brake lines, unions, and flexible hoses, particularly at the rear. The ball joint wear and coil spring fracture also warrant a close check of the front suspension bushes, drop links, and anti-roll bar links, as these components share the same load paths and corrosion environment.
