2015 Volkswagen Polo 1.8L Petrol · PL65 WHH

The most recent MOT test for this 2015 Volkswagen Polo was conducted on 2025-11-01 and resulted in a passing outcome, marking the vehicle’s most recent inspection without any recorded defects. However, the overall maintenance trend over the past few years is not entirely reassuring. The vehicle failed its 2024-11-11 MOT with two major faults—horn non-functionality and a supplementary restraint system warning lamp indicating a fault—which suggests there may be underlying issues with the electrical system or wiring harness that have not been fully resolved. While the preceding MOTs from 2023 onward were clean, the presence of recurring advisories, particularly regarding brake disc wear, indicates that the braking system has been subject to gradual degradation over time, warranting closer attention. The recorded mileage of 74,701 miles for a vehicle aged approximately 11 years represents a moderate annual usage rate of around 6,791 miles per year, which is within the expected range for its class. This level of mileage does not suggest excessive wear beyond what would be typical for a car of this age, but it does imply that the vehicle has been driven regularly rather than left in a stationary state for prolonged periods. However, the absence of significant mileage gaps does not necessarily mean the vehicle has been subjected to harsh conditions—it could reflect consistent, moderate usage. For context, if the car had been driven at a higher rate or subjected to more demanding conditions, components like the suspension, drivetrain, and exhaust system would likely show more pronounced signs of wear, particularly in the form of increased clunking, rattling, or fluid leaks. Given the MOT history, the most critical areas for inspection during a test drive and pre-purchase examination include the braking system and electrical components. The advisories from 2023 regarding near-side and off-side rear brake discs being worn, pitted, or scored but not seriously weakened indicate that the discs are nearing the end of their serviceable life. On a test drive, listen for uneven brake pedal travel, excessive vibration or shuddering during braking, or signs of brake fluid contamination, which could signal impending disc or pad failure. Inspect the brake discs for deep grooves, scoring, or excessive thickness reduction, and check for any signs of warping or binding in the calipers. If the discs are worn to within 1.5mm of their minimum thickness, they should be replaced to prevent overheating, warping, or failure under load. Additionally, the major failure in 2024 highlights potential electrical issues that should be thoroughly investigated. The horn’s non-functionality could stem from a faulty horn relay, wiring fault, or a failing horn unit itself, and the supplementary restraint system warning lamp suggests a fault in the airbag deployment mechanism, likely related to the seat belt pretensioners or the airbag control module. Test the horn’s operation by pressing the button and ensuring it produces a clear, consistent sound—no intermittent or weak responses. Inspect the wiring harness for any signs of damage, corrosion, or loose connections, particularly around the horn and airbag components. If the electrical system is suspected of being unreliable, consider having a qualified mechanic perform a full electrical diagnostic test to identify the root cause of these failures. Beyond the MOT advisories, it is prudent to check the vehicle’s service history for any recorded brake system maintenance, including disc and pad replacements, as well as fluid top-ups for the hydraulic braking system. The brake fluid should be replaced every 2–3 years or more frequently if the vehicle has been driven in stop-and-go traffic or at high altitudes, where fluid can absorb moisture and degrade. Finally, given the vehicle’s age, pay particular attention to the suspension components, including coil springs, shock absorbers, and suspension bushes, for signs of wear or failure, such as excessive clunking when driving over bumps or uneven tyre wear patterns. A thorough visual inspection of the suspension for rust, cracks, or excessive play in the mounting points is also advisable.
