2009 Mazda 6 2.2L Diesel · VX09 YFD

The current roadworthiness of this Mazda 6 is concerning, as the maintenance trend shows a distinct decline in structural and mechanical integrity. The most recent test from May 2025 highlights significant corrosion issues affecting the rear sub-frame, suspension arms, and inner sills. While these components are currently deemed not seriously weakened, the presence of structural corrosion on a vehicle of this age indicates that the chassis is entering a phase where degradation may accelerate. Combined with an ongoing oil leak and recurring issues with brake disc condition, the vehicle requires immediate professional intervention to prevent these advisories from becoming catastrophic failures. The vehicle has covered 116,171 miles over seventeen years, averaging approximately 6,800 miles annually. This usage pattern is consistent and suggests the car has been used as a regular commuter rather than sitting idle for extended periods. There are no significant gaps in the MOT history that would imply long-term neglect or storage, though the frequency of failures suggests that maintenance has often been reactive rather than preventative. The history shows a clear pattern of owners addressing faults only when forced to do so during the annual test, rather than performing routine servicing between inspections. A prospective buyer must prioritize a detailed inspection of the underside, specifically focusing on the extent of the corrosion on the rear sub-frame and inner sills. The history of tyre neglect, including two instances of tyres being driven until the cords were exposed, suggests the vehicle may have been subjected to poor wheel alignment or general lack of care, which often leads to accelerated wear on suspension bushings and steering components. You should also verify the status of the DPF system, as previous warnings indicate potential issues with the diesel particulate filter that could lead to expensive repairs. Given the recurring brake imbalances and binding issues noted in 2020, a thorough check of the entire braking system is essential to ensure the calipers and discs are functioning correctly.
