2017 Mazda 6 2.2L Diesel · BN17 XUX

The most recent MOT test passed on 29 January 2026, but it carries significant advisories that indicate a shift in the vehicle's maintenance profile. While the car maintained a clean record from 2020 through 2024, the recent history shows a notable decline in the condition of consumables. The transition from a clean pass to a dangerous failure for tyre tread depth in early 2025, followed by the current advisories for the entire braking system, suggests that the vehicle is moving into a period of required heavy maintenance. The overall trend is currently worsening, moving from a period of stability into a phase where wear-and-tear components are reaching the end of their serviceable life. The recorded mileage of 59,819 miles over nine years equates to approximately 6,647 miles per year, which is relatively low for a vehicle of this class. This usage pattern is generally positive for the long-term mechanical integrity of the engine and drivetrain, as it implies less cumulative stress on internal components. However, low annual mileage can sometimes be a double-edged sword; it can lead to longer periods of inactivity which may contribute to the pitting and scoring observed on the brake discs. The lack of high-frequency usage can also allow moisture to build up in fluids or cause components like brake calipers to seize or bind due to a lack of regular movement. A prospective buyer should prioritise a thorough inspection of the braking system. The advisories for thin front pads and worn, pitted, or scored discs on both the front and rear axles mean that a complete replacement of pads and discs is likely necessary in the near future. During your test drive, pay close attention to any rhythmic grinding noises or high-pitched squealing when applying the brakes, which indicates significant pad wear. You should also feel for any vibration or shuddering through the steering wheel or brake pedal, which is a classic symptom of warped or unevenly worn discs. Additionally, check for any pulling to one side during deceleration, as this could indicate a binding caliper or uneven pressure. Finally, given the previous failure regarding tyre tread depth, you must inspect the current tyres for both legal depth and structural integrity. Look specifically for uneven wear across the tread, which could suggest worn suspension bushes or incorrect wheel alignment. Because the vehicle has seen lower annual mileage, check the tyre sidewalls for any signs of perishing or fine cracking, which indicates age-related rubber degradation. It is also advisable to verify the service history to ensure that time-sensitive maintenance, such as brake fluid changes and oil services, has been performed according to the manufacturer's calendar intervals rather than solely based on mileage.
