2016 Mazda 6 2.2L Diesel · LO66 DLJ

The most recent MOT test on the 2016 Mazda 6 was conducted on 2025-09-10 and resulted in a clean pass, with no recorded defects. This follows a consistent pattern of passing MOTs from 2020 onwards, though the vehicle did exhibit persistent brake disc wear advisories in 2021 and 2022. The advisories from those years—both near-side and off-side rear brake discs showing pitted or scored surfaces, but not to a point that compromises structural integrity—suggest a gradual, long-term wear pattern rather than sudden deterioration. The absence of such advisories in the intervening years implies that while the brake discs are nearing their operational lifespan, they have not yet reached a critical state that would fail an MOT. This stability in maintenance records is reassuring, though the buyer should remain vigilant about the brake system’s condition as the discs continue to degrade. The recorded mileage of 35,940 miles for a vehicle aged approximately ten years is unusually low, averaging just 3,594 miles per year—a rate that typically indicates either minimal usage or prolonged periods of stationary storage. Such low mileage can lead to several potential issues, particularly in components that degrade over time rather than through wear from driving. For instance, standing for extended periods may cause brake discs to corrode internally, leading to binding calipers or uneven brake pad wear when the vehicle is eventually put into service. Additionally, fluids such as brake fluid, coolant, and transmission fluid can degrade over time due to evaporation, oxidation, or contamination, even without active use. Tyres, in particular, are susceptible to sidewall cracking or perishing from prolonged exposure to environmental elements, which can compromise their structural integrity and safety. The absence of recent mileage accumulation suggests that the vehicle may have spent significant time idle, which warrants careful inspection of these stationary-related wear and degradation risks. Given the brake disc advisories from 2021 and 2022, the prospective buyer should prioritise a thorough examination of the rear brake system. During a test drive, listen for any signs of uneven brake pedal travel, a pulsating or shuddering sensation when braking, or excessive noise from the rear brakes, which could indicate warped discs or binding calipers. Visually inspect the brake discs for further pitting, scoring, or signs of warping, and check the brake pads for consistent thickness and wear. If the discs are approaching their maximum allowable thickness, the buyer should budget for a replacement, as the pads will need to be replaced shortly thereafter. Additionally, ensure that the brake fluid is fresh and free from contamination, as old brake fluid can corrode brake components and reduce braking effectiveness. If the advisories have resolved since 2022, the buyer should still monitor the discs closely, as they may continue to wear at a steady rate. For the rest of the vehicle, given the low and infrequent mileage, the buyer should focus on age-appropriate checks that address potential issues arising from prolonged storage rather than from driving wear. Inspect the tyres for signs of sidewall perishing, cracks, or separation, as these can lead to sudden blowouts or reduced handling stability. Check the tyre tread depth for uniformity and ensure there are no areas of excessive wear, which could indicate alignment or suspension issues. The 12-volt battery should be tested for charge retention and overall health, as low usage can lead to sulphation or weak cells. If the battery is more than a few years old, consider replacing it to prevent unexpected failures. The suspension system, including coil springs, shock absorbers, and suspension bushes, should be examined for signs of wear or excessive play, particularly at the rear, where the advisories were noted. Finally, check the fluid levels and condition of the engine oil, coolant, and transmission fluid, as these should be replaced according to the manufacturer’s time-based intervals rather than mileage-based ones, given the vehicle’s low usage. A thorough visual inspection of the undercarriage for rust, leaks, or structural integrity is also advisable, especially if the vehicle has been stored in a damp or exposed environment.
