2015 Mazda 6 2.2L Diesel · AX64 EKA

The latest MOT test on 2026-05-14 resulted in a passing outcome, but the vehicle’s maintenance history reveals a pattern of recurring advisories that suggest moderate wear and potential underlying issues requiring attention. While the 2025 tests were clean, the 2024 and 2023 MOTs show persistent tyre wear and structural concerns, with the 2023 test also flagging a major tyre defect on the offside front inner tyre. The 2025 failure for rear tyre tread depth below legal limits indicates that tyre management has not been consistently proactive, and the current advisories—particularly the near-side front inner track rod end ball joint play and front brake disc wear—highlight areas where wear progression may be accelerating. This trend, combined with the high recorded mileage, suggests that while the vehicle is currently roadworthy, it has not been serviced with the same diligence as a lower-mileage model, and further deterioration could become critical if not addressed soon. The vehicle’s mileage of 163,660 miles at 11 years old represents a usage rate of approximately 14,878 miles annually, which is significantly higher than the industry average for its age. Such rapid mileage accumulation accelerates wear on consumables like tyres, brakes, suspension components, and drivetrain elements, as evidenced by the MOT history. The rear tyre failures in 2024 and 2025, particularly the deep cuts and tread wear nearing legal limits, underscore the importance of tyre rotation and replacement at appropriate intervals. Additionally, the high mileage increases the likelihood of suspension and drivetrain wear, such as the near-side front track rod end ball joint play and potential subframe corrosion, which may require more frequent inspections or replacement. The absence of service records or a clear maintenance log further complicates assessing the true state of internal components like the engine, transmission, and exhaust system, where time-based degradation—such as oil sludge or coolant system corrosion—could be more pronounced. For a prospective buyer, this Mazda 6 presents a number of critical inspection points to prioritise before purchase. The near-side front inner track rod end ball joint with slight play is a recurring advisory that may indicate progressive wear or misalignment. On a test drive, listen for clunking noises from the front suspension, particularly when cornering or over bumps, and check for uneven tyre wear patterns that could signal alignment or steering system issues. The front brake discs, while not seriously weakened, show signs of pitting and scoring, which may lead to reduced braking performance if not addressed. Inspect the brake pads for thickness and listen for grinding noises during braking, as this could indicate disc warping or binding calipers. The rear subframe corrosion, though not excessive, is a structural concern that may worsen with time, especially if the vehicle is driven in harsh conditions. Visually inspect the subframe mounts for rust progression and check for any excessive play or noise when the vehicle is in motion. Beyond mechanical checks, the tyre condition is paramount. The recent MOT failures highlight that the rear tyres are worn to or near the legal limit, and the front tyres show signs of uneven wear and sidewall damage. Replace all tyres to ensure uniform grip and tread depth, as worn tyres increase the risk of hydroplaning and reduce fuel efficiency. Given the high mileage, consider checking the vehicle’s 12V battery health, as prolonged idling or standing can accelerate corrosion in the battery terminals and lead to failure. Additionally, since the vehicle has not been serviced with a service book, verify the fluid levels—particularly the engine oil, brake fluid, and coolant—using the manufacturer’s specifications. Older vehicles like this are particularly susceptible to time-based fluid degradation, so top-ups or full replacements may be necessary. Finally, inspect the exhaust system for leaks or excessive emissions, as corrosion or component failure could lead to costly repairs and affect the vehicle’s roadworthiness and environmental compliance. A thorough mechanical inspection by a qualified technician, including a full suspension and drivetrain check, is strongly recommended before finalising the purchase.
