2013 Mazda 6 2.2L Diesel · SL13 FPY

The vehicle currently presents a concerning state of roadworthiness with a worsening trend in mechanical neglect. While the most recent test in February 2026 at 151,049 miles resulted in a failure due to excessive exhaust emissions and worn brake discs, the preceding history shows a pattern of recurring faults that are only partially addressed. The recurrence of high emissions readings in both 2025 and 2026 suggests an ongoing engine issue or sensor failure that has not been professionally rectified. At 151,049 miles over 13 years, the Mazda 6 follows a consistent usage pattern of approximately 11,600 miles per year, which is typical for a vehicle of this age. The data shows steady accumulation between annual tests, with roughly 4,600 miles covered between March 2024 and March 2025. However, the high mileage combined with the increasing frequency of failures for mechanical components, like suspension bushes and brake hardware, indicates that the vehicle is entering a phase where component fatigue is significant rather than just preventative maintenance. A physical inspection must prioritize the deteriorating suspension and braking systems. The March 2025 test identified worn nearside front suspension arm bushes and deteriorating rear bushes, which often lead to unpredictable handling and premature tyre wear. The February 2026 failure regarding pitted and scored brake discs on the nearside front and rear indicates that the braking system is reaching the end of its life. You should also investigate the oil leak noted in 2025 to determine if it is a minor seal weep or a more significant gasket issue that could explain the high emission readings.
