2021 Audi Q4 E-Tron S Line 40 Electric · YP71 GWJ

The Audi Q4 e-tron S Line 40 presents a stable and highly favorable maintenance trend, culminating in a completely clean pass on 31 October 2025 at 9,471 miles. The absence of any defects or advisories in the most recent test confirms the vehicle currently meets all structural, mechanical, and emissions roadworthiness standards without reservation. The maintenance trend remains firmly stable, showing no signs of deterioration or unresolved mechanical issues. The recorded mileage pattern reflects exceptionally light usage for a five-year-old vehicle, averaging just 1,894 miles annually. Between the 2024 test at 6,830 miles and the 2025 test at 9,471 miles, the car accumulated 2,641 miles over a twelve-month period, indicating consistent but minimal driving. Such low annual mileage suggests the vehicle spent significant periods stationary, which carries its own mechanical implications despite the clean test record. With no recurring mechanical faults or structural advisories documented, the primary inspection focus shifts to the effects of prolonged inactivity rather than chronic wear. A buyer must physically inspect the condition of the 12-volt auxiliary battery, as low-mileage electric vehicles frequently suffer from deep discharge during extended static periods. Examine the brake discs and calipers for surface corrosion and binding, a common issue when vehicles stand without regular use preventing the pads from wiping the rotors clean. Check the tyre sidewalls and tread for flat-spotting or premature perishing, as tyres age chronologically regardless of mileage. Verify the charge port mechanism and high-voltage battery cooling system for proper operation, ensuring the electric drivetrain has not suffered from lack of use.
