2017 Audi A4 3.0L Petrol · LS11 PLS

The Audi A4 presents a stable roadworthiness profile in its most recent MOT history, with no defects recorded in either the April 2025 tests—one passed and one failed—both at identical mileages of 31,847–31,848 miles. The absence of advisories or failures tied to mechanical or structural issues suggests that core components such as suspension bushes, coil springs, brake discs, and binding calipers have remained within acceptable tolerances. The repeated passes and fails at the same mileage in April 2025 are unusual, though the lack of defects implies the failure may have been administrative rather than technical. Prior tests in 2023 and 2024 also show clean records, reinforcing that no recurring mechanical trends—such as corrosion, exhaust emissions, or drivetrain wear—have been flagged. This consistency points to either meticulous maintenance or, given the low mileage, minimal stress on the vehicle’s systems. The mileage pattern is striking: just 31,848 miles over nine years equates to roughly 3,539 miles annually, well below the UK average for a vehicle of this age. The gap between the 2023 and 2024 tests (13,362 to 24,291 miles) spans nearly a year with no recorded mileage accumulation, suggesting the car may have been stored or used very sparingly. This low usage could explain why no wear-related advisories have appeared, but it also raises questions about the condition of fluids—such as brake fluid, coolant, and engine oil—which degrade over time regardless of mileage. Buyers should verify whether these have been recently changed, as prolonged inactivity can lead to seal deterioration or corrosion in components like the cooling system or fuel lines. Given the clean MOT history, the primary focus for a prospective buyer should be on components typically overlooked in basic maintenance but critical for long-term reliability. The suspension—particularly the rear bushes and coil springs—should be checked for stiffness or cracking, as low-mileage vehicles can still suffer from age-related material fatigue. Brakes, despite no MOT advisories, warrant inspection for fluid condition and pad/disc thickness, especially if the car has been stationary for extended periods. Structural integrity, including sills, wheel arches, and underbody corrosion, should be scrutinised, as rust can develop even with minimal mileage if the vehicle has been exposed to moisture or salt. Finally, the exhaust system’s condition—looking for leaks or corrosion—is prudent, given that low-mileage cars may not have had recent emissions-related servicing. While the MOT record is reassuring, these areas require hands-on verification to ensure the car’s longevity.
