2007 Volkswagen Polo 1.2L Petrol · CA56 HNF

A recurring weakness in the front drive‑shaft constant‑velocity boot, compounded by a single major exhaust emissions failure in early 2022, dominates the mechanical story of this 2007 Polo. The vehicle has since cleared two successive MOTs – February 2022 and February 2023 – with no defects recorded, indicating that the major emissions issue was addressed, yet the boot deterioration remains an advisory that has persisted across several years. At 96,986 mi the car averages just over 5 000 mi per annum, a mileage figure low for a nineteen‑year‑old model. The relatively modest annual accumulation suggests light usage or periods of inactivity, which can be hard on rubber components such as CV boots that age even without high mileage. The MOT record shows a gap in 2019, but otherwise a regular testing cadence, and the mileage progression appears steady rather than spiking, reducing the likelihood of hidden high‑wear periods. Prospective buyers should inspect the nearside front outer drive‑shaft joint for any grease seepage around the boot, audible clicking or clunking when the steering is turned under load, and vibration that intensifies with acceleration or deceleration. A deteriorated boot can allow contaminants to enter the joint, leading to premature bearing wear; replacement of the boot and a thorough inspection of the joint for wear are advisable before committing. The offside rear service brake was flagged as binding in the 2022 advisory; a test drive should include a firm, progressive brake application to feel for any pedal drag, uneven pedal travel, or a pulling sensation to one side. Additionally, the earlier exhaust lambda‑sensor failure warrants a check of the exhaust system for leaks, sensor operation, and fuel mixture stability, as lingering issues could re‑trigger emissions failures. Addressing the brake binding and confirming the exhaust system’s integrity will provide confidence that the vehicle’s roadworthiness aligns with its current MOT status.
