2020 Audi S4 Black Edition TDI Quattro A 3.0L Diesel · RO20 UHF

The Audi S4 Black Edition TDI Quattro presents as roadworthy following the most recent test on 5 March 2026 at 70,940 miles, which returned a pass with no defects recorded. The maintenance trend is stable across the available history, with every annual examination from March 2023 through to March 2026 resulting in a pass apart from a single failure on 25 February 2026 at 70,893 miles that was cleared within eight days and also logged no defects. No recurring advisories or mechanical faults appear in the record, indicating consistent statutory compliance. Annual mileage averages 11,823 across the vehicle's six years, a typical figure for this age of executive saloon. The records show steady accumulation: 46,352 miles at the 20 March 2023 test, 52,215 on 15 March 2024, 61,577 on 13 March 2025, and 70,940 by 5 March 2026. The gap between the February 2026 failure and the March 2026 pass covers only 47 miles, suggesting the car was presented early then re-tested after administrative or undocumented rectification. No long dormant periods or sudden high-use spikes are evident. The clean MOT ledger means no specific suspension bushes, brake discs, coil springs, or corrosion issues have been formally flagged for the buyer to chase. The unexplained failure at 70,893 miles with zero defects noted warrants a check of the test centre paperwork to confirm whether it was a documentation error or a withdrawn contest. Given the Quattro drivetrain and age, a physical inspection should still verify haldex coupling service history, front control arm bush condition, and underside structural integrity for road salt corrosion. Prospective owners should also confirm tyre makes match and tread is even across all four corners, as consumable wear is not captured once a pass is issued. The absence of advisories across four years implies prior keepers addressed wear before each test, a positive care pattern for a 2020 performance diesel.
