2023 Audi Q4 E-Tron S Line 40 Electric · WP23 KCA

High-intensity usage defines the roadworthiness profile of this electric SUV, which accumulated 59,332 miles over three years before clearing an MOT test on 20th May 2026. This test followed an immediate retest on the same day, which had originally resulted in a failure due to both rear tyres having tread depths below the legal limit of 1.6mm, classified as dangerous defects, alongside an advisory for the nearside front tyre wearing close to the edge. This tire-focused failure highlights the heavy load and torque demands placed on the rubber by a high-mileage EV drivetrain, though the prompt rectification allowed the vehicle to secure a pass. Accumulating nearly 20,000 miles annually places this Audi well above average usage parameters for a three-year-old vehicle, signaling intensive fleet, motorway, or commercial deployment. This rapid mileage accumulation means high-wear components like suspension linkages, wheel bearings, and braking architecture have experienced accelerated operational cycles compared to lower-mileage counterparts of the same age. Buyers should note that while the braking system on an electric vehicle relies heavily on regenerative deceleration, the physical friction brakes and suspension components still bear the brunt of substantial vehicle weight over extended distances. When inspecting the vehicle on a test drive, pay close attention to the tracking and steering geometry, as the previous severe tyre wear patterns on both rear edges and the nearside front can indicate past alignment issues or heavy cornering loads. Listen carefully for any structural knocks, clunks, or vibrations from the wheel arches and suspension wishbones when traversing uneven road surfaces or speed humps. Ensure the steering wheel remains centred without pulling to either side and check for any abnormal humming noises from the wheel hubs that would suggest premature bearing fatigue from high-mileage running. Finally, verify the remaining tread depth and brand consistency across all four tyres, ensuring that the replacement rubber fitted after the recent MOT failure matches the load and speed ratings specified by the manufacturer for the Q4 e-tron platform. Inspect the condition of the alloy wheels for curbing or impact damage that may have contributed to the rapid tyre wear or alignment drift. A thorough physical check underneath the vehicle will confirm whether the high-mileage deployment has caused any premature degradation to the underbody shields, subframe mounting points, or air suspension components if fitted.
