2023 Audi E-Tron S Line 55 Quattro Electricity · PH03 AOH

A single dangerous defect has been recorded on this Audi e-tron S Line 55 Quattro, and it centres squarely on the front tyres. The 30 December 2025 test resulted in a Dangerous fail because the nearside front tyre was below the 1.6mm minimum tread depth requirement, with a corresponding advisory noting that the offside front tyre had worn close to the legal limit and was worn on the edge. Beyond that tyre-related entry, the same date also carries a clean pass record with no further defects or advisories logged, meaning the braking system, suspension, steering, emissions, lighting, and structural integrity items were all considered satisfactory at the time of test. Because the failure and the clean pass share the same date, the vehicle was almost certainly failed on presentation, the offending tyre replaced, and then re-submitted and passed the same day. With only one test cycle on file so far, there is no longitudinal pattern to interpret, but the fact that one tyre reached a dangerous state while the other was merely approaching the legal limit suggests uneven front axle wear rather than a global tyre ageing issue. The recorded mileage of 28,502 miles across approximately three years of age equates to an annual accumulation of around 9,500 miles, which sits broadly within the expected range for a premium electric SUV used as a mix of commuter and longer-distance transport. There is no second MOT cycle on record, so there are no testing gaps or sudden mileage jumps to interpret. The absence of any extended out-of-test period is consistent with continuous road use rather than long-term storage, which is relevant for an EV because prolonged standing can affect 12V auxiliary battery health and allow brake discs to corrode through lack of use. Given the relatively short ownership window covered by MOT data, the mileage-based wear picture is essentially restricted to consumables rather than major drivetrain components. For a prospective buyer, the immediate priority is a thorough inspection of the remaining original or recently fitted tyres, including the offside front that was flagged as worn on edge. Uneven shoulder wear on the front axle of a quattro-equipped vehicle can point to misalignment, worn suspension bushes, or bent components following a kerb impact, so it is worth checking for uneven tread wear across the full width of each tyre and confirming that all four tyres are of matching make, size, and speed rating. On a test drive, listen for clonking or knocking from the front suspension over speed humps and uneven road surfaces, as worn lower control arm bushes or anti-roll bar linkages can produce audible disturbance that would not necessarily be flagged on an MOT ramp. Also pay attention to steering precision; any vagueness, pulling to one side under braking, or vibration through the steering wheel could indicate geometry issues that contributed to the edge wear noted on the offside front. The brake system should be evaluated dynamically even though it passed without advisories, because the e-tron relies heavily on regenerative braking, which means the friction brakes can corrode or seize through under-use. On a test drive, perform several firm stops from around 30 mph and listen for any grinding, binding, or judder, and confirm that the vehicle rolls freely when coming to a stop with no residual drag from a sticking caliper. The 12V auxiliary battery, which supports systems such as lighting, infotainment, and the high-voltage contactors, should be checked for healthy cranking behaviour and absence of warning messages on startup, since low-voltage issues are a common cause of EV electrical faults. Finally, request evidence that the dangerous tyre was replaced prior to the subsequent pass and inspect the spare or repair kit, as the recorded failure demonstrates that the front tyres have been worked hard relative to the vehicle's modest mileage, and any remaining original rubber of similar age should be replaced as a matter of course.
