2020 Audi Q8 S Line 55 Tfsi Mhev Quat A 3.0L Petrol · K33 HAA

The most recent MOT test on 2026-01-07 resulted in a clean pass, marking a positive turnaround from the previous year’s failures, which included both dangerous failures regarding the near-side front tyre’s tread depth dropping below the legal minimum of 1.6mm and persistent advisories about offside and near-side front tyres wearing close to the legal limit on the tread depth. While the 2024 and 2023 MOTs recorded only advisories rather than outright failures, the pattern of tyre-related issues suggests a recurring concern that has not been fully resolved. This trend indicates that the vehicle’s tyre management may have been suboptimal, potentially due to uneven loading, alignment discrepancies, or driving habits that exacerbate edge wear. The fact that the latest MOT cleared these defects without further intervention implies either a corrective action taken prior to the 2026 test or a stabilisation of the tyre wear profile, but the buyer should remain vigilant to ensure no underlying mechanical issues—such as misaligned wheels, suspension wear, or excessive camber—are contributing to the persistent edge wear. The recorded mileage of 47,158 miles for a 2020 Audi Q8 S Line is consistent with a moderate annual usage rate of approximately 7,860 miles per year, which is within the expected range for a vehicle of this age and performance class. Such mileage suggests a balance between regular use and periods of inactivity, which can lead to certain wear patterns—particularly in components that degrade more slowly, such as seals, gaskets, and fluids—rather than rapid consumption of consumables like tyres or brake pads. However, the presence of tyre wear advisories spanning multiple MOTs, even at this relatively low mileage, warrants closer inspection, as edge wear can indicate underlying issues like incorrect wheel alignment, suspension misalignment, or improper tyre installation. The absence of significant mileage gaps does not preclude the possibility of prolonged standing, which could accelerate corrosion in brake systems, particularly if the vehicle was left in a damp or salty environment, leading to potential binding calipers or corrosion on brake discs. For the prospective buyer, the most critical immediate inspection should focus on the front tyres, given the recurring MOT advisories. Visually verify the tread depth across the entire contact patch, ensuring no further reduction has occurred since the last MOT, and check for signs of uneven wear patterns that might suggest misalignment or suspension issues. On a test drive, listen for any unusual noises from the front wheels, such as clunks or rattles, which could indicate loose suspension components or worn suspension bushes. Additionally, inspect the front suspension for signs of excessive play or binding, particularly around the control arms and struts, and check for any fluid leaks around the wheel bearings or hubs. The near-side and offside tyre wear advisories also raise concerns about potential camber or toe-in misalignment, which should be confirmed by a professional alignment check if the wear pattern persists. Beyond the tyres, given the vehicle’s age and mileage, the buyer should conduct a thorough inspection of the brake system, paying particular attention to the front discs for signs of corrosion, warping, or uneven wear, which can indicate prolonged standing or poor braking performance. Check for any binding or grinding noises when applying the brakes, which could signal seized calipers or warped discs. Inspect the brake fluid reservoir for contamination or low levels, as brake fluid degrades over time and can lead to reduced braking efficiency. The suspension components, including coil springs, shock absorbers, and suspension bushes, should also be examined for signs of wear or damage, particularly around the front wheels, where the wear advisories have been noted. Finally, consider a professional inspection of the exhaust emissions system, as the Q8’s hybrid-electric powertrain may have specific service intervals for catalytic converter and emissions-related components that are not always reflected in standard mileage-based servicing schedules. Additionally, verify the vehicle’s service history for any scheduled fluid changes, such as the coolant, transmission fluid, and differential oil, which should have been conducted in line with Audi’s recommended intervals, particularly given the vehicle’s age.
