2014 Ford KA 1.2L Petrol · MJ14 DXH

Progressive structural corrosion and recent emissions failures define the mechanical trajectory of this vehicle. While it achieved a pass on 2026-03-09, this followed a failure on 2026-03-03 caused by an inoperative engine management light and exhaust lambda readings outside specified limits. The roadworthiness trend is shifting from a clean record in 2023 toward recurring advisories regarding the rear sub-frame and brake system integrity. An average annual accumulation of approximately 3,017 miles over twelve years indicates a low-usage profile. While this results in minimal mechanical wear on the engine and gearbox, such low mileage often correlates with the type of surface and structural corrosion now appearing on the rear sub-frame. The vehicle has likely spent significant time stationary, which can accelerate the degradation of exposed metal components compared to a vehicle in constant active use. Immediate attention should be directed to the rear underside of the vehicle to assess the extent of the sub-frame corrosion and the state of the rear inner brake hose ferrules. During a physical inspection, verify that the corrosion on the sub-frame remains superficial and has not compromised the structural integrity of the mounting points. The corrosion on the brake hose ferrules is a specific point of failure that requires monitoring, as these components are critical for maintaining hydraulic pressure during braking. On the test drive, listen for any abnormal exhaust noise or a drone from the rear, which would indicate a recurrence of the previous back box leak. Ensure the engine management light remains extinguished and the vehicle does not exhibit erratic idling or hesitation under acceleration, which would suggest the recent lambda and MIL faults have not been fully resolved. Any unusual vibrations or knocks from the rear of the chassis should be noted as potential indicators of further sub-frame or suspension deterioration.
