2012 Mazda 6 2.2L Diesel · WJ12 VPZ

The most recent MOT entry on 13 May 2025 shows a Pass with no defects recorded, restoring a clean roadworthy status following the immediate-prior test five days earlier on 8 May 2025 that was logged as a Fail, also with no defects recorded. This pattern of a Pass and Fail occurring within the same week, both bearing no advisory or defect notes, is unusual and suggests either an administrative re-classification, a pre-test rectification of an unrecorded issue, or a database entry peculiarity rather than a sudden mechanical deterioration. The three preceding tests in January 2022, February 2023, and January 2024 all passed cleanly with no advisories, which indicates a stable presentation at the test station over the preceding three-year window. Overall, the trend at the point of testing was effectively clean, with the lone failure appearing anomalous within an otherwise unblemished record. Annual mileage across the recorded life of this 2012 Mazda 6 is notably modest, averaging roughly 5,800 miles per year to reach 81,375 miles. The interval between the January 2022 and February 2023 tests covers around 13 months, while the gap from February 2023 to January 2024 is approximately eleven months; combined with the low overall annual figure, this points to a vehicle that has covered limited distance between tests. Low-mileage examples of vehicles approaching their fourteenth year can present their own concerns: ageing rubber components, dried brake fluid, oxidised fuel, and stagnant coolant systems deteriorate with time rather than use, and long idle periods can promote corrosion on underbody structures even when road mileage is low. There is no mileage recorded on the database to confirm intermediate annual use, so the figures represent test-station odometer readings only. Because the recorded history contains no advisories or categorised defects, the MOT file alone does not flag any specific wear pattern in the braking system, suspension components, exhaust, or structural areas. A buyer should still carry out a physical inspection focused on the items most likely to fail by age rather than mileage on this model. Check the rear brake calipers for binding seizure, a known weakness on Mazda 6 of this generation, and inspect the front and rear discs for lipping and surface corrosion. Examine the front lower wishbones, front suspension bushes, and coil springs for cracking or collapse, and inspect the rear trailing arm bushes for deterioration. A thorough underbody examination for corrosion, particularly around the rear wheel arches, sills, and subframe mounting points, is essential given the car's age, and a compression test or borescope check on the 2.2 diesel engine, if fitted, would help confirm internal health that the MOT process does not assess. The absence of recorded advisories is a neutral data point rather than a positive endorsement of mechanical soundness, as MOT testing is a statutory roadworthiness screen and not a comprehensive condition report. Risk should be regarded as moderate pending a hands-on appraisal. Buying Score: 55. Risk Level: Medium.
