2021 Audi Q4 E-Tron S Line 35 Electric · OV71 SYH

The most recent MOT on 17 January 2026 was a clean pass with no recorded defects, indicating that the vehicle currently meets the statutory safety standards. However, the preceding twelve months show a pattern of tyre‑related failures – a major cut on the off‑side front tyre in December 2025 and a major cut on the nearside rear tyre in December 2024 – each accompanied by advisory notes about nails in the remaining tyres. The successful test in January 2025, despite an advisory nail, suggests that at least some of the tyre issues were addressed, but the recurrence of major cuts points to a need for careful monitoring of tyre condition and possibly the underlying causes of punctures. At 45,169 miles recorded for a 2021 model, the vehicle averages roughly 9,000 miles per year, which sits comfortably within the normal UK usage envelope. There is no evidence of unusually high annual mileage that would accelerate wear on high‑cost components such as the electric drivetrain, suspension bushings, or brake rotors. The mileage figure also suggests the car has not been subject to prolonged periods of inactivity that could lead to battery sulphation or brake disc corrosion, although the relatively low annual figure does mean that age‑related degradation of rubber components should still be inspected. Given the history of tyre cuts, a prospective buyer should give the tyres a thorough visual and tactile inspection. Verify the DOT code to confirm the tyres are not older than six years, as ageing rubber can develop cracks and become more susceptible to puncture even without external objects. Look for any signs of sidewall bulging, tread separation, or embedded foreign objects, and ensure the tread depth meets the legal minimum of 1.6 mm on all four wheels. During a test drive, pay attention to any vibration, pulling to one side, or thumping noises that could indicate internal tyre damage, mis‑alignment, or worn suspension components such as bushings or control arm bearings that may have been stressed by previous tyre failures. Beyond the tyres, the e‑tron’s high‑voltage battery and associated cooling system should be inspected for coolant level, hose condition, and any warning lights on the instrument cluster. Confirm that the vehicle has received the latest OTA software updates and that the charging port and cable show no signs of corrosion or wear. Check the brake discs for surface rust or uneven wear, especially since regenerative braking can mask traditional wear patterns; a gentle, progressive brake application should feel smooth without pulsation. Finally, verify that the service book contains regular oil‑free coolant changes, tyre rotations, and any recommended battery health checks, as these time‑based services are critical to maintaining reliability in a relatively low‑mileage, five‑year‑old electric vehicle.
