2021 Audi A4 S LN BLK ED 40TDI Mhev Q SA 2.0L Diesel · S77 ODL

Consistent roadworthiness has been the defining characteristic of this vehicle, which has maintained a clean record across its two mandatory inspections. The most recent test conducted on 24 October 2025 resulted in a pass with no defects recorded, mirroring the outcome of the previous inspection in October 2024. This trend suggests that the primary safety-critical systems, including the braking, lighting, and suspension components, have remained within the required tolerances during the vehicle's initial years of operation. Accumulating 51,528 miles over a five-year period equates to an average annual usage of approximately 10,306 miles, a figure that aligns with standard expectations for a modern diesel saloon. This consistent mileage profile indicates that the vehicle has been subjected to regular, ongoing use rather than prolonged periods of inactivity or extreme high-mileage motorway cycles. Mechanically, this suggests that the drivetrain and ancillary systems have been kept in a state of operational readiness, avoiding the specific risks associated with long-term storage, such as seized brake calipers or degraded rubber seals. Prospective buyers should focus their inspection on the high-torque drivetrain and the sophisticated multi-link suspension system characteristic of this model. Given the mileage, listen closely for any audible knocks or clunks from the front and rear axles when traversing uneven road surfaces, as these can indicate early-stage wear in the suspension control arm bushes or ball joints. During the test drive, ensure the S-tronic transmission shifts smoothly through all gears without hesitation or judder, particularly when transitioning between lower gears in stop-start traffic, as the MHEV system and gearbox integration are critical to the vehicle's performance. While the MOT history does not highlight specific issues with the braking system, the weight and power of this Audi model place significant demand on the discs and pads. Check for any vibration through the brake pedal during firm deceleration from higher speeds, which could point to disc warping or uneven pad wear. Additionally, verify that the electronic parking brake engages and releases silently and promptly. As the vehicle is now entering its post-warranty period, a physical inspection of the underside for any signs of oil misting around the turbocharger or transmission housing is advisable, as these areas are prone to minor leaks that may not always be captured during a standard MOT inspection.
