2022 Audi Q4 E-Tron S Line 40 Electric · TR14 AML

The most recent DVSA MOT test for this 2022 Audi Q4 e-tron S Line 40 was conducted on 5 August 2025, at which point the vehicle passed without any advisories or defects being recorded against it. With only a single MOT entry appearing in the official history, the documented maintenance trend is effectively neutral to positive, as the absence of advisory items or failure categories suggests the vehicle was presented in a sound mechanical state at its most recent roadworthiness examination. It should be noted, however, that because the Q4 e-tron was first registered in 2022, it would not have required an MOT until its fourth anniversary in 2026, meaning this 2025 test likely represents either an early voluntary check or an out-of-cycle inspection. A clean single test therefore provides limited longitudinal data, and the prospective buyer should not interpret it as a guarantee of underlying mechanical condition across all vehicle systems. Turning to the recorded mileage of 14,519 miles against a four-year age, this equates to approximately 3,630 miles per annum, which is notably below the national average and indicative of either light private use, a predominantly urban commute, or extended periods of standing between journeys. While low annual mileage reduces wear on major drivetrain and suspension components, it introduces its own set of age-related concerns that are not necessarily captured in MOT testing. The mechanical implications of low-mileage use tend to centre on calendar-driven degradation rather than distance-driven wear, meaning components such as brake discs, callipers, brake fluid, coolant, and the 12-volt auxiliary battery can all deteriorate through inactivity even when the odometer reading remains low. Given the clean MOT record and the low usage profile, physical inspection should focus on issues commonly associated with vehicles that have spent significant time stationary. Brake discs should be examined for surface corrosion, pitting, or any evidence of binding callipers, as standing vehicles frequently develop rust ridges on disc faces that can cause brake shudder or vibration under initial pedal application. Tyres warrant particular attention for sidewall perishing or cracking from age, even if the tread depth appears adequate, as the rubber compound degrades with calendar age regardless of mileage; check the production date markings on the sidewalls to confirm they are not significantly older than the vehicle itself. The 12-volt battery, which is separate from the high-voltage traction pack, should be load-tested, as low-mileage operation with short journeys often leads to chronic undercharging and premature battery failure. Brake fluid is hygroscopic and typically requires replacement every two to three years irrespective of mileage, so verify the date of the last fluid change, and similarly inspect the coolant system, air conditioning refrigerant, and any transmission or reducer oil service intervals as stipulated by Audi. On a road test, particular attention should be paid to the regenerative braking system, which on the Q4 e-tron can mask underlying mechanical brake issues, so test the vehicle with the regeneration set to a low or off setting to assess the conventional friction brakes independently. Listen for any suspension clonks or knocks over uneven surfaces, which could indicate worn anti-roll bar bushes, control arm bush deterioration, or coil spring fatigue from age-related corrosion. Finally, verify the operation of all driver assistance and infotainment systems, confirm the service book is stamped in line with Audi's fixed service intervals, and request any available diagnostic readout from Audi or a specialist to confirm the high-voltage battery state of health, as this is the single most expensive component on the vehicle and is not assessed during a standard MOT examination.
