2015 Audi A4 2.0L Diesel · AP04 RUS

The most recent MOT test on 2025-12-01 resulted in a passing grade, though it included several advisories that indicate ongoing but non-failing mechanical conditions. The trend in the vehicle’s MOT history is mixed, with a notable failure in 2022-12-01 due to a major defect in the near-side front lower suspension arm pin or bush, which had already been flagged as worn in previous tests but not deemed severe enough to fail the vehicle. Subsequent MOTs have shown recurring advisories on brake wear—both rear discs and pads—suggesting that while the brakes remain functional, their condition is deteriorating over time. The suspension advisories, particularly the deteriorated near-side front suspension arm dust cover and the worn rear suspension arm, also point to a pattern of wear that could escalate if not addressed, especially given the vehicle’s high mileage. The presence of a preheating system fault and underinflated tyres further highlights areas requiring attention, though these do not currently compromise roadworthiness. The recorded mileage of 151,902 miles for a vehicle aged approximately 11 years represents a usage rate of around 13,809 miles annually, which is significantly higher than the average for its class. This level of mileage, particularly without evident long periods of inactivity, accelerates wear on critical components such as brakes, suspension, and drivetrain elements. The rapid accumulation of miles suggests that the vehicle has undergone substantial operational stress, leading to accelerated degradation of consumables like brake pads and discs, as well as potential stress fatigue in suspension and steering linkages. While high mileage alone does not necessarily indicate imminent failure, the combination of frequent use and the presence of recurring advisories warrants closer scrutiny to prevent unexpected breakdowns or safety issues. For a prospective buyer, the most critical areas to inspect during a physical examination include the rear brake system, as the advisories on worn discs and thin pads indicate that the braking performance may be compromised. Look for signs of excessive heat discolouration or glazing on the brake discs, which could suggest overheating or uneven wear. Listen for unusual grinding or squealing noises during braking, which may indicate that the pads are nearly worn out or that the discs are pitted to the point of requiring replacement. Additionally, check the rear brake pads for consistent thickness—if they are significantly below the legal minimum, replacement is strongly advised to prevent damage to the discs. During a test drive, monitor the braking response for any signs of pulsation or shudder, which could indicate warped discs or binding calipers. If the vehicle has been driven at high speeds or under heavy loads, the rear brakes may have suffered more wear than the front, so prioritise a thorough inspection of the rear assembly. Beyond the brakes, the suspension system shows signs of wear that should be addressed to maintain ride quality and safety. The near-side front suspension arm’s deteriorated dust cover and the worn rear suspension arm suggest that the ball joints and bushings may be nearing the end of their service life. Inspect the suspension arms for excessive play or binding, particularly around the ball joints, which could lead to clunking noises when driving over bumps or uneven surfaces. Listen for a persistent clunking or rattling sound in the front or rear suspension during acceleration or deceleration, as this often indicates worn suspension components. Visually check the suspension bushes for cracks or excessive oil staining, which can compromise their integrity and lead to premature failure. If the vehicle has been driven with significant load or towing, the suspension components may have experienced additional stress, further accelerating wear. Finally, given the high mileage and the advisories on the engine preheating system and tyre pressure, it is prudent to verify that all fluids—including engine oil, brake fluid, and coolant—are at the correct levels and not showing signs of degradation. Check for leaks around the engine bay and exhaust system, as fluid leaks can exacerbate corrosion and further damage components. Additionally, inspect the tyres for sidewall cracking or perishing, which can weaken their structural integrity over time, even if they remain above the legal tread depth.
