2021 Audi A5 S Line 40 Tfsi Mhev S-A 2.0L Petrol · WN71 LRU

The vehicle passed its most recent MOT test on 14 May 2026 with a single advisory noting that the front brake pads are wearing thin. This is a relatively minor observation and does not represent a failure point, but it does indicate that the pads are nearing the end of their useful service life and will likely require attention within the next six to twelve months depending on driving style and conditions. Reviewing the broader MOT history, the 2024 tests passed with no defects recorded, while the 2025 test flagged both front tyres as being worn close to the legal limit, and the latest 2026 test has shifted attention to the front brake pads. This pattern suggests a vehicle that is fundamentally sound and structurally compliant, but is beginning to show the expected wear on its primary friction components as it accumulates mileage. The trend is stable rather than deteriorating, with no structural, corrosion, suspension, or exhaust advisories recorded, which is reassuring for a five-year-old Audi. With a recorded mileage of 45,044 miles over approximately five years, the vehicle is averaging around 9,000 miles per year, which sits squarely within the typical range for a privately used executive car. There are no significant gaps in the MOT history that would suggest extended periods of standing, nor is there any evidence of rapid mileage accumulation between tests. This consistent, moderate usage pattern is mechanically favourable, as it implies regular driving that keeps the engine, transmission, brakes, and electrical systems properly exercised. The moderate annual mileage also suggests that major drivetrain components such as the clutch, turbocharger, and dual-clutch or automatic transmission are unlikely to have been excessively stressed, although it remains important to verify that the regular servicing schedule has been adhered to. For a prospective buyer, the front brake pad advisory should prompt a physical inspection of the discs as well, since worn pads frequently accelerate disc wear, and any scoring, lipping, or uneven surface corrosion on the front brake discs would indicate that a refurbishment or replacement is imminent. On a test drive, listen for any grinding or squealing from the front wheels under light pedal pressure, and pay attention to any vibration or shudder through the steering wheel during braking, which would suggest disc run-out or warping. The previous tyre advisories also warrant checking the current front pair for even wear across the tread, and ensuring that the replacement tyres fitted were of matching规格 on the same axle to avoid any handling irregularities or premature uneven wear caused by mixing tread patterns or brands. Given the vehicle's age and moderate mileage, there are several time-based items that warrant attention regardless of the clean MOT record. Tyres older than five years can develop sidewall perishing and cracking even if the tread depth remains legal, so check the DOT date codes on the sidewalls and inspect the rubber carefully for any hairline cracks. A five-year-old vehicle is also approaching the typical replacement interval for its 12V auxiliary battery, and a weak battery can cause a host of electrical faults on modern Audi platforms, so it is worth confirming the battery's age and having it load-tested if possible. The brake fluid should have been renewed within the last two to three years regardless of mileage, as it is hygroscopic and degrades over time, and the coolant, which on Audi vehicles is often the long-life G13 formula, should be checked for its replacement interval. Finally, verify the service book stamps and digital service history to confirm that the cambelt, if applicable to this MHEV powertrain variant, and the DSG or automatic transmission fluid have been serviced in line with the manufacturer's schedule, as these are costly items if neglected.
