2015 Mazda 3 2.2L Diesel · LS15 BCV

The vehicle is currently roadworthy but the maintenance history indicates a pattern of reactive rather than proactive care. While it passed its most recent MOT in March 2024 at 101,375 miles, this followed two failures within a single week. These failures reveal that the owner only addressed critical defects when forced by the testing process. The trend shows a concerning disregard for basic service items, as the car was allowed to operate with dangerously thin rear brake pads and perished front tyres until they reached the point of failure. At 101,375 miles, the Mazda 3 has averaged approximately 9,200 miles per year, which is consistent with typical usage for a car of this age. There is a significant gap in data between the February 2022 test at 56,719 miles and the March 2023 test at 81,208 miles, representing over 24,000 miles in a single year. This burst of mileage likely contributed to the accelerated wear observed in subsequent tests, particularly regarding the thinning of tyres and the exhaustion of the rear brake components. A buyer must conduct a thorough physical inspection of the braking and suspension systems. The record shows recurring issues with the rear brakes, including a binding offside wheel and excessive parking brake movement, which suggests the calipers may be seizing or the mechanism is poorly lubricated. The persistent oil leak noted in both 2023 and 2024 requires close scrutiny to ensure it remains a minor weep rather than a developing gasket failure or crankcase seal issue. Given the exhaust emissions failure in early 2024, the engine health should be verified for signs of incomplete combustion or faulty sensor readings that could lead to future failures.
