2011 Mazda 6 2.2L Diesel · FG11 RYY

A persistent theme across the MOT record is progressive corrosion affecting the rear sub‑frame, rear suspension arms and both front brake pipes, coupled with tyre wear that has repeatedly approached the legal limit. Each annual test from 2022 through 2025 has flagged the same areas, and although the most recent inspection in November 2025 was a pass, the advisory list has not materially changed, indicating that the underlying rust issues have not been fully remedied and that tyre wear remains a looming concern. At 130,870 miles over roughly fifteen years the vehicle averages about 8,700 miles per annum, a figure that sits squarely within normal usage patterns for a family saloon. There are no significant gaps in the MOT chronology, suggesting the car has been driven consistently rather than sitting idle for extended periods. This steady mileage accumulation aligns with the observed wear on consumables such as tyres, brake hoses and seat‑belt webbing, and it reinforces the expectation that corrosion‑prone components will have been exposed to road‑salt and moisture over a long service life. When you inspect the car, give particular attention to the rear sub‑frame and the lower rear control arms. Feel for any flex or creak when applying pressure over bumps, and listen for metallic knock that could indicate structural weakening beyond the superficial corrosion noted in the advisories. Examine the front brake pipes for signs of active corrosion, rust streaks or any dampness around the fittings; a compromised pipe can lead to fluid loss and a spongy pedal. On a road test, verify that the brake pedal feels firm and that there is no noticeable pull to one side, which would suggest binding or a leak in the corroded lines. The tyres deserve immediate scrutiny: the near‑side rear tyre has been reported as worn close to the legal limit and edge‑wear is evident, while the opposite rear tyre shows side‑wall damage and cracking. Even if the tread depth still meets the minimum, the uneven wear pattern points to possible alignment or suspension issues that should be corrected before new tyres are fitted. The seat‑belt webbing on the near‑side rear is already slightly frayed, and the headlamp lenses have a residual product that may marginally reduce illumination. A qualified mechanic should replace the compromised seat‑belt, clean the headlamp lenses, and assess whether the corrosion on the sub‑frame and suspension arms warrants reinforcement or component replacement to ensure long‑term structural integrity.
