2020 Audi S4 Black Edition TDI Quattro A 3.0L Diesel · SH70 AFU

This Audi S4 has maintained a consistently clean MOT history across three consecutive tests, all passing without defects or advisories. The most recent inspection on 4 July 2025—just ten months prior to today—confirms the vehicle remains roadworthy under current UK standards. There is no evidence of recurring mechanical issues or advisory trends, suggesting the previous owner adhered to basic maintenance intervals. However, the absence of defects does not preclude hidden wear, particularly in high-stress components like turbochargers, suspension mounts, or drivetrain seals, which are common failure points in this model at this mileage. The recorded mileage progression indicates steady usage without abrupt spikes or prolonged inactivity. At 66,159 miles over six years, the vehicle averages around 11,000 miles annually, a rate typical for a performance-oriented model like this. The gap between the 2023 and 2024 tests—roughly 7,600 miles in just over a year—suggests no extended periods of neglect, though it also means consumables like brake pads, tyres, and wiper blades may have been replaced less frequently than recommended. The most recent MOT was conducted at 66,159 miles, aligning closely with the current odometer reading, which implies the vehicle has not been driven significantly since testing. Given the lack of MOT advisories, a prospective buyer should prioritise a thorough inspection of the turbocharged diesel engine, particularly the intercooler, turbocharger bearings, and exhaust manifold for signs of oil leaks or excessive carbon buildup. The suspension—especially the rear multi-link geometry—should be checked for worn bushes or coil spring fatigue, as these components often fail silently in high-mileage Quattro models. Front and rear brake systems warrant scrutiny: while no binding calipers were recorded, uneven pad wear or glazed discs could indicate past neglect. Finally, the subframe and wheel arches should be examined for corrosion, as this model is prone to rust in these areas despite its relatively young age. A pre-purchase diagnostic scan for fault codes would also reveal any unresolved electrical or emissions-related issues.
