2021 Audi E-Tron S Line 55 Quattro Electric · X7 DLW

The 2021 Audi e-tron S Line 55 quattro has demonstrated consistent roadworthiness over its MOT history, with no defects recorded across the most recent three tests. The latest pass on 2026-03-12 at 22,408 miles confirms the vehicle remains compliant with current UK regulations, though the absence of advisories or minor faults does not preclude underlying issues requiring closer inspection. The pattern of clean MOTs suggests either meticulous maintenance or a vehicle that has not yet encountered significant wear, but this does not guarantee future reliability without further scrutiny. The recorded mileage of 22,408 miles over five years—approximately 4,482 miles annually—is notably low for a vehicle of this age, particularly given the e-tron’s electric drivetrain, which typically sees higher usage in urban and hybrid markets. The gap between the 2024-09-30 test at 15,155 miles and the 2025-03-13 test at 16,287 miles indicates a 1,132-mile accumulation over just six months, a rate that slows dramatically to 6,121 miles over the following year. This irregularity could imply periods of inactivity or seasonal storage, which may have contributed to potential wear on components like suspension bushes or battery health. The lack of MOT entries between 2023 and 2024 also raises questions about whether the vehicle was tested privately or not at all during that period. Given the clean MOT record, a buyer should prioritise an independent inspection of high-wear areas that are not always captured in standard MOT testing. The suspension system—particularly coil springs, bushes, and dampers—should be examined for uneven wear or corrosion, as electric vehicles often experience subtle suspension degradation due to weight distribution. Brake components, including calipers and discs, warrant close attention, especially if the vehicle has been stored for extended periods, as moisture can accelerate corrosion. The high-voltage battery and thermal management system, while not MOT-tested, should be assessed for any signs of degradation or fluid leaks, as these are critical to the e-tron’s longevity. Finally, the underbody should be inspected for corrosion, particularly around wheel arches and the sills, where salt and moisture accumulate over time.
