2020 Audi S4 TDI Quattro Auto 3.0L Diesel · PF20 DFE

The vehicle is currently roadworthy, but the maintenance trend shows a shift toward deferred consumable replacements. While it passed the most recent test in February 2026 at 45,283 miles, the tester flagged thin rear brake pads and noted that the front discs and pads are nearing their service limit. This indicates that the vehicle is entering a phase where significant braking system overhauls will be required, moving away from the clean records seen in the previous years. The mileage pattern is consistent with a low-use vehicle, averaging approximately 7,500 miles per year. The record shows a steady progression from 21,549 miles in early 2023 to 45,283 miles in early 2026. This usage suggests the car has not been subjected to high-stress commuting, which generally benefits the Quattro drivetrain and engine components. However, the gap of 11,000 miles between the 2025 and 2026 tests explains the sudden appearance of wear issues after those inspections. A buyer should prioritize a thorough inspection of the braking hardware to check for binding calipers or uneven wear given the thin material on the rear pads noted in the 2026 report. The 2025 advisory regarding uneven edge wear on the rear tyres suggests a potential alignment issue or worn suspension bushes that should be verified to prevent premature tyre degradation. Since no structural corrosion or emission failures have appeared in the history, the focus remains entirely on these mechanical wear items and the condition of the suspension geometry.
