2021 Audi Q4 E-Tron S Line 40 Electric · MK71 BHO

The Audi Q4 e-tron in question presents a clean MOT history, with the most recent test on 16 June 2025 at 44,212 miles passing without any defects. This aligns with the previous inspection on 25 September 2024 at 42,229 miles, which also recorded no issues. The absence of advisories, minor faults, or major defects across both tests suggests a stable maintenance trend, with no signs of recurring mechanical or structural problems. Given the vehicle’s age—just over five years—and its relatively low mileage, the lack of recorded concerns is particularly notable. However, the sparse MOT data means this verdict relies heavily on the assumption that no other issues have arisen outside these two tests, particularly since the last inspection was over a year ago. The mileage accumulation of roughly 8,842 miles per year is typical for a vehicle of this age, neither excessively high nor abnormally low. The gap between tests—approximately nine months—is within the standard 12-month window, though the next MOT would now be overdue by nearly 13 months. This delay isn’t inherently alarming, but it does raise a question about whether the vehicle has been stored or used lightly since June 2025. Without further records, it’s impossible to confirm whether routine servicing has been maintained, particularly for components like brake fluid, suspension fluids, or tyre condition, which degrade over time even with minimal use. For a prospective buyer, the absence of MOT defects does not eliminate the need for a thorough pre-purchase inspection. Given the vehicle’s age and the reliance on electric drivetrain components, particular attention should be paid to the battery cooling system, high-voltage cables, and inverter health—areas where silent degradation can occur without visible symptoms. The suspension, including coil springs, anti-roll bars, and bushings, should be checked for wear or corrosion, especially if the car has been driven on varied or poorly maintained roads. While the brakes passed without issue, binding calipers or uneven disc wear could still develop, so a visual and functional inspection of the braking system is advisable. Finally, the underbody and wheel arches should be scrutinised for signs of corrosion, particularly in regions prone to salt or moisture exposure, even if the MOT history shows no prior concerns.
