2017 Audi A4 2.0L Diesel · X7 JNP

The latest MOT test on 2026-08-14 resulted in a passing outcome, though it included an advisory regarding the rear brake pads showing significant wear down to 1.1mm of their original thickness, which is below the legal minimum of 1.5mm. This trend, when compared to the vehicle’s history, reveals a pattern of recurring advisories related to brake components and suspension elements, particularly the offside rear coil spring mounting and drive shaft joint. While the 2025 MOT was clean, the 2024 and 2023 tests highlighted persistent issues with corrosion in the coil spring mountings and uneven tyre wear, suggesting that while the vehicle has maintained roadworthiness, underlying wear and potential long-term degradation are present. The fact that the latest MOT passed does not negate the need for proactive maintenance, as these advisories indicate ongoing or developing mechanical concerns that should be addressed before they escalate into major failures. The recorded mileage of 100,882 miles for a vehicle aged nine years represents a reasonable annual usage rate of approximately 11,209 miles per annum, which is consistent with typical driving patterns for this model class. However, the absence of a recent service history or clear mileage gaps between MOT tests could imply either infrequent use or periods of prolonged idling, both of which can accelerate wear on consumables and stationary components. Prolonged standing, for instance, can lead to brake disc corrosion, caliper binding, and fluid degradation in the braking system, while suspension elements like coil springs and bushings degrade more slowly but are susceptible to corrosion when exposed to moisture. The drive shaft joint failure recorded in 2023 underscores the importance of monitoring for excessive vibration or clunking noises, particularly when the vehicle is driven at higher speeds, as this joint is critical to drivetrain integrity. Given the recurring advisories and wear patterns observed in the MOT history, the prospective buyer should prioritise a thorough inspection of the braking system, focusing on the rear brake pads, discs, and calipers for signs of uneven wear, corrosion, or binding. During a test drive, listen for any grinding noises from the rear brakes when applying the pedal, as this could indicate pad-to-disc contact or warping. Additionally, check for a soft or spongy brake pedal, which may signal fluid degradation or air in the system. The offside rear coil spring mounting corrosion and the drive shaft joint failure suggest that the suspension and drivetrain should be inspected for any signs of excessive play, clunking noises from bushings or mounts, or excessive vibration at highway speeds. If the coil springs are visibly corroded or deformed, they may need replacement to prevent structural failure or uneven ride quality. For the tyres, which have shown significant edge wear and are nearing legal limits, the buyer should verify that the remaining tread depth is consistent across all four tyres and that there are no signs of uneven wear patterns that could indicate misalignment or suspension issues. Inspect the sidewall for any cracks, bulges, or signs of perishing, which can compromise tyre integrity, especially given the vehicle’s age. The nearside rear tyre’s wear close to the legal limit is a cause for concern, as this may require replacement soon to maintain safety and fuel efficiency. As for fluids, given the vehicle’s age and the potential for prolonged idling, check the brake fluid level and condition, as well as the condition of the cooling and transmission fluids, which should be replaced according to the manufacturer’s service schedule. Finally, a visual inspection of the exhaust system for leaks or corrosion, and a check of the 12V battery health and connections, are essential, particularly if the vehicle has been stored for extended periods, as standing corrosion and battery degradation can occur without use.
