2007 Volkswagen Polo 1.2L Petrol · AJ07 RLO

Corrosion and progressive wear dominate the mechanical narrative of this 2007 Polo – the MOT record shows repeated advisories for rear brake pipe and sub‑frame mounting corrosion, front suspension arm pins and bushes approaching wear limits, and rear shock absorbers leaking oil, while light‑ and major‑failure items such as stop‑lamp and registration‑plate lamp faults have also appeared. The most recent test on 4 March 2026 was a pass, but only with the same rear‑brake‑pipe and sub‑frame corrosion advisories persisting, indicating that the vehicle has not remedied its core rust issues despite a generally improving pass/fail ratio in recent years. At 77 480 mi the car averages just over 4 000 mi per annum, well below the typical usage for a nineteen‑year‑old model. Such low annual mileage often points to intermittent or light duty rather than constant road‑wear, yet the MOT history reveals periods of inactivity – notably the dual‑test day in February 2022 where a failure for an inoperative engine MIL coincided with extensive under‑tray corrosion – suggesting that prolonged stand‑still may have accelerated surface rust. Mechanically, the modest mileage reduces the expected fatigue on drivetrain and brake components, but it does not protect against the progressive corrosion observed on the brake pipe, sub‑frame and under‑tray areas, which can compromise structural integrity over time. When inspecting the vehicle, concentrate on the rear brake pipe for any signs of rust flaking, moisture ingress or reduced flexibility, and verify that the pipe remains securely clamped and free of leaks under pressure. Examine the sub‑frame mounting points for pitting or weakening metal, and listen for any creaking or clunking when the car is rocked or driven over bumps, which would indicate compromised mounting. The front suspension arm pins and bushes, flagged repeatedly as worn, should be checked for excessive play by applying force to the wheel hub and feeling for any looseness; any knocking or uneven tyre wear would corroborate the advisory. The rear shock absorbers, noted for light oil misting and a serious fluid leak in 2023, must be inspected for oil stains on the shock bodies or dampness on the rear wheel arches, and a test‑drive should reveal any bouncing or reduced damping when traversing potholes. Finally, confirm that all lighting functions are operational – the stop‑lamp, registration‑plate lamp and direction indicators have failed in past tests – by cycling each light and observing for dimming or non‑operation. Given the recurring corrosion and wear items, a prospective buyer should budget for replacement of the rear brake pipe, a thorough sub‑frame corrosion treatment or repair, renewal of front suspension arm bushings, and fitting of new rear shocks. A comprehensive pre‑purchase inspection by a qualified mechanic, focusing on these specific areas, will reveal whether the corrosion is superficial or has progressed to a point that could affect long‑term roadworthiness.
