2012 Volkswagen Polo 1.4L Petrol · KC05 LON

A chronic pattern of brake service instability runs through the MOT record, with major “excessively fluctuating” brake readings recorded on both front wheels in the latest 2026 test and on the rear wheel in 2025, alongside recurring disc‑wear advisories each year. The front exhaust leak noted in 2026 adds a further non‑structural defect, while earlier serious shock‑absorber fluid loss in 2022 has not been revisited in subsequent tests. Together these entries suggest that the braking system has been a persistent weak point rather than an isolated failure, and the most recent outcome does not indicate a clear resolution. At 93,818 mi the car averages roughly 6,700 mi per annum, which sits comfortably within normal usage for a fourteen‑year‑old small family car. The MOT history shows annual testing from 2022 onward with no prolonged gaps, implying the mileage has been accrued consistently rather than in a short, high‑stress period. This steady accumulation means wear on consumables such as tyres, brake pads and suspension components is likely to be proportional to age, but the brake‑fluctuation failures point to a specific degradation that exceeds what mileage alone would predict. When inspecting the brakes, feel for any pulsation or sponginess on the pedal, especially under light to moderate braking, and listen for any high‑pitched squeal that could indicate warped discs or worn pads. Given the repeated “excessively fluctuating” readings, the hydraulic circuit—flexible brake hoses, caliper pistons and the master cylinder—should be examined for internal leaks or air ingress, and the discs should be measured for thickness and surface scoring. A thorough visual check of the parking‑brake lever for free play is also warranted, as excessive movement was flagged in 2025. The front exhaust leak will manifest as a faint hissing or ticking noise, particularly at idle or under acceleration, and may produce a faint exhaust smell in the cabin. The rear shock absorbers, which suffered a fluid leak and reduced damping in 2022, should be pressed to confirm resistance and checked for any oil seepage around the mounting points. Finally, verify that the near‑side rear registration lamp operates correctly and that the parking brake now holds firmly, as both items were recorded as defective in the recent MOT cycle. Addressing these specific areas will give a realistic picture of the car’s roadworthiness before purchase.
