2010 Audi A5 S Line TDI Quattro S-A 3.0L Heavy oil · DE04 OCS

A pattern of intermittent testing gaps and a singular failure in June 2025 defines the recent roadworthiness profile of this Audi A5. While the most recent test on 15 May 2026 resulted in a pass with no recorded defects, the history shows a significant period of inactivity between July 2019 and June 2025. This gap in official testing documentation means that the continuity of the vehicle's mechanical compliance cannot be verified through DVSA records for that six-year interval. The transition from a failure in 2025 to a clean pass in 2026 suggests that whatever issue caused the previous failure was addressed, but the lack of annual testing during the middle years remains the primary characteristic of this record. The vehicle has covered 140,339 miles over its sixteen-year lifespan, averaging approximately 8,771 miles per year. This accumulation rate is consistent with typical UK usage for a vehicle of this age and does not suggest excessive heavy-duty operation or extreme low-mileage idling. However, the mechanical implications of the six-year testing gap are more significant than the mileage itself. During periods where a vehicle is not being regularly inspected or driven, components such as rubber suspension bushes, seals, and various fluid-carrying lines can undergo degradation that may not be immediately apparent through mileage alone. Given the absence of specific advisories or defect descriptions in the provided history, the inspection should focus on the components most likely to have been affected during the undocumented period. A prospective buyer should pay close attention to the integrity of the suspension system, specifically looking for knocks or clunks when navigating uneven surfaces or speed bumps, which could indicate perished bushes or worn coil springs. Furthermore, because the 2025 failure was not detailed, it is prudent to inspect the underside for signs of fluid leaks from the engine or gearbox, as well as any evidence of corrosion on the subframe or brake pipes that may have developed during the years of irregular usage. During a test drive, the steering should be evaluated for any pulling to one side or vibrations through the steering wheel, which could point to underlying issues with the steering rack or suspension geometry. The braking performance must also be scrutinised; any pulsation through the brake pedal or a feeling of judder under deceleration could indicate warped discs or binding calipers. While the 2026 pass indicates the vehicle met the minimum standards at that time, the lack of detailed advisory history means a physical inspection of the tyre tread depth and the condition of the brake pads is a necessary precaution to supplement the official record.
