2014 Vauxhall Zafira 2.0L Diesel · JJ10 KAT

The Vauxhall Zafira’s most recent MOT tests reveal a concerning pattern of inconsistency rather than clear deterioration. The vehicle passed in December 2024 and December 2023 but failed twice in December 2025—once on the same day—despite identical mileage readings of 84,670 miles. This suggests either a temporary administrative error or an undocumented mechanical issue that persisted undetected until the final inspection. The absence of recorded defects across all tests implies the tester did not identify any major failures, but the double failure in December 2025 warrants scrutiny of components that might have been overlooked or were at a critical threshold. No advisories or recurring faults are logged, which could indicate the vehicle was either well-maintained or that minor issues were not systematically addressed. The mileage progression of 7,056 miles annually aligns with typical usage for a vehicle of this age, though the abrupt jump from 73,968 miles in December 2023 to 74,133 miles by December 2023—just 165 miles in six days—appears anomalous and may reflect an inaccurate reset or a brief period of heavy use. The gap between tests is consistent at one year, with no extended periods of inactivity or rapid mileage accumulation beyond this minor inconsistency. The lack of a service history complicates interpretation, but the steady mileage suggests the vehicle has not been left unused for prolonged periods, which could mitigate some wear concerns. Given the absence of recorded defects, the primary focus for an in-person inspection should centre on components prone to silent failure or gradual degradation. The double failure in December 2025, despite no logged issues, raises suspicion of potential brake binding or caliper seizure—common in older vehicles where fluid leaks or corrosion go unnoticed. Suspension bushes and coil springs should be examined for excessive wear or cracking, particularly around the wheel arches and sills, where corrosion often compromises structural integrity. The exhaust system, while not explicitly flagged, warrants inspection for leaks or rust-through, especially near the catalytic converter and muffler, given the vehicle’s age. Tyres, though not mentioned in the record, may have been replaced between tests; verify tread depth and uniformity to rule out uneven wear from alignment or suspension issues. Finally, check for signs of oil leaks under the bonnet, as these often precede more serious drivetrain failures.
