2020 Audi A5 S Line 35 TDI Mhev S-A 2.0L Diesel · LO20 AOK

The most recent MOT certificate from January 2026 indicates a successful pass with no recorded defects. When evaluating the overall maintenance trend, the vehicle shows a positive trajectory. Although the August 2024 inspection flagged several advisories regarding tyre wear and perishing on all four corners, the subsequent clean passes in 2025 and 2026 suggest that these consumables have been replaced and the vehicle's roadworthiness has been restored to a high standard. This indicates a responsive approach to maintenance by the previous keeper. The recorded mileage of 18,091 miles over a six-year period is significantly lower than the UK average, representing an annual usage of approximately 3,015 miles. While low mileage is often viewed as a benefit due to reduced wear on the engine, gearbox, and suspension components, it carries specific mechanical implications for a diesel MHEV engine. Low-frequency usage can lead to carbon buildup within the Diesel Particulate Filter (DPF) and may not allow the engine to reach optimal operating temperatures regularly. You should confirm whether the vehicle has been used for longer journeys to ensure the exhaust after-treatment system remains healthy. During your inspection and test drive, you must be vigilant regarding the condition of the tyres, as the 2024 advisories suggest a history of uneven wear and age-related degradation. Examine the sidewalls for any signs of cracking or perishing and check that the tread is even across the width of the tyre. During the test drive, listen for any rhythmic humming or vibration that could indicate tyre unbalance or uneven wear patterns, and check for any steering pull that might indicate a need for wheel alignment. Additionally, inspect the brake discs for heavy corrosion or pitting, which is common in low-use vehicles, and ensure the calipers are not binding by checking for excessive heat or a dragging sensation after driving. Given the low mileage profile, it is also essential to verify the service history for time-based maintenance. Ensure that engine oil and brake fluids have been changed according to the manufacturer's yearly intervals rather than solely on mileage, as fluids can degrade through moisture absorption and oxidation over time. Check the condition of the 12V battery, as vehicles that sit idle for extended periods are prone to voltage drops and capacity loss. Finally, inspect the underside for any signs of superficial corrosion or fluid leaks that may have developed from the vehicle standing for long periods without regular thermal cycling.
