2013 Audi Q7 3.0L Diesel · ML13 MVG

The most recent MOT test on 2025-07-11 resulted in a pass, but the vehicle’s overall maintenance history reveals a pattern of recurring issues that suggest a need for heightened scrutiny. While the 2024 and earlier MOTs were clean, the 2025 failure and the subsequent pass highlight persistent front brake wear and tyre conditions that have not been fully resolved. The repeated advisories on tyre wear close to legal limits—particularly on the rear inner tyres—indicate a lack of proactive tyre management, which could lead to uneven traction, hydroplaning risk, or premature tyre failure if not addressed. The snapped brake cable during the 2025 failure is a critical failure point, as it compromises the vehicle’s braking performance and safety. This suggests either a failure to replace worn brake components or a history of neglect in maintaining the hydraulic or cable-assisted braking system. The vehicle’s recorded mileage of 135,756 miles at 13 years old represents a moderate annual usage rate of approximately 10,443 miles per year, which is within the expected range for a car of this age and class. However, the absence of service records or a clear maintenance schedule raises concerns about how the vehicle has been operated over its lifespan. Lower mileage could imply periods of prolonged standing, which often accelerates wear on components like brakes, suspension, and fluids due to corrosion, standing corrosion, or fluid degradation. Conversely, higher mileage would typically indicate more aggressive use, leading to accelerated wear on suspension bushes, coil springs, brake pads, and tyres. The lack of recent service history means that consumables such as brake fluid, coolant, and transmission fluid may have degraded over time, particularly if the vehicle has been driven in varying temperatures or conditions. For the prospective buyer, the most urgent concerns stem from the front brake system and tyre wear. The brake pads reaching the wear indicators in 2025 necessitate immediate replacement, as worn pads compromise stopping power and can lead to brake dust buildup, reduced grip, and potential damage to brake discs. During a test drive, listen for a grinding or scraping noise when applying the brakes, which indicates metal-to-metal contact between the pads and discs. Additionally, check for a pulsating or shuddering sensation while braking, which may signal warped brake discs or binding calipers. Inspect the brake fluid level and condition; if it appears dark or contaminated, a full flush is required. The snapped cable failure suggests a failure to maintain the brake system’s integrity, so verify that the cable or hydraulic lines are secure and free from cracks or leaks. Beyond the immediate issues, the tyre advisories—particularly the wear on the inner edges—point to improper alignment or excessive load distribution. Inspect the tyres for uneven wear patterns, which could indicate misalignment, suspension issues, or incorrect tyre pressures. The vehicle’s age and usage profile warrant a thorough inspection of the suspension components, including coil springs, shock absorbers, and suspension bushes, as these are prone to wear and can lead to clunking noises or a bouncy ride. Check for signs of rust or corrosion on the chassis, particularly around the wheel arches and undercarriage, as prolonged standing can accelerate structural degradation. Finally, verify the battery’s health, as older vehicles may struggle with cold starts or electrical systems if the battery is aged or weak. Test the 12V battery by attempting to start the engine and checking for any electrical gremlins, such as dimming lights or malfunctioning indicators. If the vehicle has been stored for extended periods, consider a full fluid top-up, including coolant, brake fluid, and transmission fluid, to prevent freeze damage or degradation.
