2021 Audi Q5 S Line 40 TDI Mhev Quat S-A 2.0L Diesel · S26 NBL

The vehicle most recently passed its MOT on 27 February 2026 with no defects recorded. However, the overall maintenance trend reveals a period of instability during early 2025, where the car suffered a significant failure involving multiple major defects. While the subsequent passes indicate these issues were addressed, the transition from a clean 2024 record to a heavily faulted 2025 test suggests a lapse in preventative maintenance before the vehicle was brought back to a roadworthy standard. With a recorded mileage of 60,747 miles over approximately five years, this vehicle has averaged over 12,000 miles per year, which is considered high for this class of SUV. Such usage patterns typically accelerate the wear of consumables and chassis components. Prospective buyers should anticipate that the vehicle is approaching a stage where high-wear items, such as suspension bushes, engine mounts, and drivetrain components, will require closer scrutiny compared to a lower-mileage example. Particular attention must be paid to the braking system and suspension, given the history of major failures and recurring advisories. The 2025 record noted excessively fluctuating rear brakes and pitted or scored discs both front and rear. During a test drive, the buyer should be alert for any brake shudder through the pedal or an uneven stopping feel, which would indicate that the discs remain warped or the calipers are binding. The previous failure of both rear shock absorbers due to fluid leaks is also critical; ensure the vehicle does not exhibit excessive bouncing or instability over undulations, as worn dampers can negatively impact tyre wear and overall handling. The previous engine management indicator lamp failure warrants a thorough review of the service history to determine the root cause of the malfunction. It is essential to verify whether this was a simple sensor replacement or a more systemic engine issue. Given the high mileage and the MHEV powertrain, the buyer should also check for any signs of oil leaks around the engine bay and ensure that the gearbox transitions are smooth. Finally, verify that the service intervals have been strictly adhered to in the digital or physical service book, as high-mileage diesel engines are heavily dependent on timely oil and filter changes to maintain long-term reliability.
