2021 Audi Q4 E-Tron S Line Launch ED 40 Electric · BW71 SBX

A clean and largely uneventful DVSA test record is the defining feature of this 2021 Audi Q4 e-tron, with two MOT passes on file and only a single non-mechanical advisory issued. The most recent examination on 13 November 2025 returned a pass with no defects or advisories recorded, continuing the trajectory established at the previous test. The only entry of any kind is a 2024 advisory noting that an offside rear outer child seat was fitted in a manner that prevented full inspection of the adult seat belt, which is a child-restraint observation rather than a mechanical or structural concern. There are no recorded failures, no corrosion advisories, no brake, suspension, tyre, or lighting defects, and no exhaust or emissions issues across the available history, indicating that no wear-related component has yet been flagged by the tester as warranting attention. The vehicle has accumulated 43,716 miles over approximately five years of use, equating to an annual average of around 8,743 miles, which sits broadly in line with typical UK driving patterns for a car of this age and class. The mileage progression between the two recorded tests, from the 2024 examination to the 2025 examination, is consistent with steady regular use rather than long periods of standing or sudden high-mileage accumulation. There is no evidence in the available data of any extended off-road period or a step-change in usage, so the mechanical implications are relatively straightforward: the braking system, tyres, suspension components, and electrical drivetrain have been exercised at a normal cadence rather than suffering the prolonged static storage that can affect EV systems, and the wear on consumables should be proportionate to the mileage covered. Given that the MOT history is essentially clean and no specific components have been flagged for attention, the buyer-facing inspection should focus on the areas most likely to show age- and mileage-related wear on a premium electric SUV, even though they have not yet triggered advisories. On a test drive, listen for any clonks, thuds, or knocking from the front suspension over uneven road surfaces, as the multi-link front arrangement can develop wear in the lower control arm bushes and anti-roll bar links; any looseness or vibration through the steering wheel on bumpy roads would warrant closer inspection of those joints. Check the brake pedal feel carefully, as regenerative braking on EVs means the friction brakes are used infrequently and can suffer from seized calipers or corroded discs, which may manifest as a binding sensation, uneven pulling under light braking, or judder when the friction brakes eventually engage at lower speeds. Inspect all four brake discs for any lipped or heavily corroded edges, as surface rust on the friction surfaces is common and usually cosmetic, but pitting or scoring across the working face suggests the caliper has been sticking. Tyre condition is worth particular scrutiny given the vehicle's weight and torque, with even wear across both axles expected and any uneven inner or outer shoulder wear potentially pointing to suspension geometry or alignment issues. The 12V auxiliary battery, which supports the vehicle's control systems on an EV, should be checked for reliable operation, particularly if the car has stood for any length of time, as a weak auxiliary battery can trigger a range of electronic warnings. Visually inspect the underside of the vehicle for any signs of fluid leakage from the electric drive units or coolant lines, as corrosion on the aluminium components or staining around suspension mounting points would be worth flagging. Finally, confirm that the high-voltage charging system functions correctly across both AC and DC methods and that all driver-assistance and infotainment systems operate without warning messages, as electronic faults on complex EVs frequently present before any mechanical issue develops.
