2018 Audi A6 1.8L Petrol · ML18 AOF

The most recent DVSA MOT test on the 2018 Audi A6 was conducted on 2026-08-27, resulting in a failure due to critical brake component deficiencies: rear brake pads were below the legal minimum thickness of 1.5 mm, and the rear brake discs were significantly and obviously worn to a point that compromises their structural integrity. This failure follows a pattern of recurring advisories and minor failures over the past three years, particularly concerning the front and rear brake systems, as well as the near-side front shock absorbers showing light oil misting—a clear indicator of internal damage or failure. While the vehicle passed in 2025-09-08, the advisories from that test—including worn brake discs and misted shock absorbers—persist, suggesting that the issues are not isolated incidents but rather ongoing wear or degradation. The combination of these failures indicates a maintenance trend that has not improved and may require immediate attention to prevent further deterioration, particularly in the braking system, which is critical for road safety. The recorded mileage of 97,849 miles for a vehicle aged eight years represents a high annual usage rate of approximately 12,231 miles per year, which is notably elevated for its age. Such mileage accumulation typically accelerates wear on consumables like brake pads, tyres, and suspension components, as well as potential stress on drivetrain and structural elements. The absence of significant mileage gaps suggests the vehicle has been in active service, likely under conditions that have contributed to the observed wear patterns. This level of usage can lead to premature fatigue in suspension bushes, uneven tyre wear, and accelerated corrosion in brake components, all of which are reflected in the MOT history. Buyers should be aware that the vehicle’s wear profile may be more aggressive than a lower-mileage example of the same age, necessitating closer monitoring of fluid levels, suspension integrity, and brake system performance. For the prospective buyer, the most pressing concerns stem from the recurring brake-related failures and advisories. The rear brake pads being below legal thickness and the severely worn rear discs are immediate red flags, as they indicate compromised braking performance and the risk of failure under heavy loads or emergency braking. On a test drive, listen for uneven brake pedal travel or a spongy or pulsating sensation, which may signal warped or warped discs, and check for excessive brake dust accumulation around the wheels, which could indicate excessive pad wear. Additionally, inspect the rear brake calipers for binding or excessive play, as this may suggest hydraulic issues or seized components. The misted shock absorbers on the near-side front suspension should be addressed promptly, as oil misting is a precursor to complete failure, leading to poor ride quality, uneven tyre wear, and potential suspension collapse. Inspect the front suspension for clunks or rattles when driving over bumps, and check for uneven tyre wear patterns, particularly on the off-side front tyre, which was also flagged in previous MOTs for nearing the legal limit and showing edge wear—a sign of alignment or camber issues. Beyond the immediate concerns, the buyer should conduct a thorough physical inspection of the vehicle’s age-appropriate wear and potential hidden issues. Given the high mileage, verify the condition of the suspension bushes and coil springs for signs of cracking or excessive play, as these can lead to alignment problems and uneven tyre wear. Check the tyre sidewall for signs of perishing, cracking, or dry rot, which can compromise tyre integrity and safety, especially if the vehicle has been stored for extended periods. Inspect the battery terminals for corrosion or loose connections, as a 12V battery in a high-mileage vehicle may struggle under load, particularly if the alternator is showing signs of wear. Additionally, because the vehicle is aged, consider checking the service history for time-based fluid servicing, such as the coolant, brake fluid, and differential/transmission fluids, which should be replaced according to manufacturer recommendations—typically every 60,000 to 100,000 miles or every two to three years, depending on the fluid type. Finally, address the off-side front tyre’s exposed ply or cords immediately, as this is a critical safety failure that must be rectified before the vehicle is re-tested.
