2022 Audi Q4 E-Tron S Line 40 Electric · WN22 ATZ

An isolated but serious safety event punctuates an otherwise sparse MOT history for this 2022 Audi Q4 e-tron S Line 40. The earliest test on file is dated 5 March 2025, which passed with no advisories, and the most recent activity on 13 March 2026 produced two simultaneous entries: one pass with no defects recorded and a separate failure under the Dangerous category for an exposed ply or cord on the nearside rear tyre. A Dangerous classification is the most severe outcome the DVSA can issue, meaning the vehicle was considered an immediate road safety risk at the point of test. The fact that the same date carries both a pass and a fail is typical of a presentation where the dangerous defect was identified, the vehicle failed, and then the tyre was replaced and the car immediately re-presented for a partial retest, which it passed. The overall record therefore contains no advisories and no repeat concerns, but the single Dangerous failure deserves full scrutiny before purchase. With 51,890 miles recorded at just four years of age, this Q4 e-tron has covered roughly 12,970 miles annually, which is a notably high accumulation rate for a premium electric SUV of this type and considerably above the typical fleet average. The mileage context carries particular mechanical relevance for an EV because high annual mileage concentrates wear on the same components that suffer on any high-use vehicle: tyres, brake discs and pads, suspension bushes, coil springs, wheel bearings, and the rolling resistance items that govern range. EV-specific concerns amplified by high mileage include brake disc corrosion from frequent light regenerative braking, accelerated tyre wear due to the vehicle's mass and instant torque delivery, and potential degradation of the high-voltage battery cells, which can manifest as reduced usable capacity rather than any testable MOT defect. There is no multi-year testing gap apparent, but the infrequency of test entries means the buyer has limited DVSA visibility into the period between March 2025 and March 2026. The Dangerous tyre failure is the only flagged item in the entire MOT history, and the precise component is worth examining carefully on inspection. A nearside rear tyre with exposed ply or cords indicates that the tread and underlying structure had worn through to the casing, almost always a consequence of running significantly under-inflated, neglecting rotation, or simply exceeding the legal 1.6 mm tread depth by a considerable margin. On a test drive, listen for any increase in road noise from the rear axle, feel for vibration through the floor on smooth motorway surfaces, and check whether the car tracks straight without pulling, as a single severely worn tyre can mask an underlying alignment issue. All four tyres should be inspected for even wear across the tread face and matching brand, size, and speed rating, and the spare or repair kit should be verified as present and serviceable. Beyond the flagged tyre, the high annual mileage warrants close attention to the mechanical items that an MOT does not directly cover. Brake discs on a high-mileage EV frequently exhibit severe edge corrosion and lipping from extended periods of light regenerative deceleration, so each corner disc edge should be felt for a pronounced ridge. The suspension should be exercised over speed humps and uneven surfaces with the windows down, listening for clonks from the front strut top mounts, anti-roll bar drop links, and the multi-link rear geometry, all known wear points on the MEB-platform Q4. Steering response should remain precise without vibration through the wheel between 60 and 80 mph, which would suggest wheel balancing or a bent rim following an earlier kerb impact. Finally, the high-voltage battery state of health should be independently verified through a diagnostic scan of the pack rather than relying on the dashboard range estimate, as no MOT entry can speak to cell degradation on this drivetrain.
