2021 Audi A6 S LN Blck ED 40 TDI Mhev SA 2.0L Diesel · AV71 KNE

The latest DVSA MOT test for this 2021 Audi A6 S 40 TDI MHEV was conducted on 2025-09-19, resulting in a passing grade with a single minor defect related to the windscreen’s integrity, which does not impair the driver’s field of vision. The MOT history over the past two years shows a consistent trend of compliance, with no failures or repeated advisories beyond the front brake pad wear advisory from the 2024 test. This stability suggests that the vehicle has been maintained within the legal and safety parameters, though the thin brake pads indicate a developing condition that warrants closer attention before they reach critical levels. The absence of structural defects, exhaust emissions failures, or warning light activations further supports a stable maintenance profile, though the advisory prompts a proactive review of brake system longevity. The vehicle’s recorded mileage of 51,502 miles at the time of this assessment represents a reasonable annual usage rate of approximately 10,300 miles, which aligns with typical driving patterns for a car of this age and engine configuration. This figure does not indicate excessive wear from high mileage alone, but it does imply that the vehicle has accumulated moderate usage over its five-year lifespan. However, the potential for prolonged periods of inactivity—such as standing for extended periods—could contribute to specific issues, including brake pad binding from moisture absorption, suspension component stiffness from lack of movement, or fluid degradation in hydraulic systems. The 40 TDI engine’s turbocharged and direct-injection design also means that oil consumption and turbo health may be influenced by idle time and short trips, so monitoring for oil leaks or turbo whine changes would be prudent. For the prospective buyer, the most critical inspection should focus on the front brake system, as the thin pad advisory from the 2024 MOT suggests wear progression that may continue. On a test drive, listen for a grinding noise during braking, which could indicate metal-on-metal contact if pads are severely worn, and check for a soft or spongy pedal feel, which may signal low brake fluid or warped discs. Inspect the front wheels for uneven wear patterns, which could point to misalignment or suspension issues exacerbated by the vehicle’s standing time. Additionally, verify the brake discs for corrosion or binding, particularly if the car has been stationary for long periods, as standing fluid can cause caliper pistons to seize. Beyond the brakes, examine the suspension for excessive clunks or rattles, which may signal worn suspension bushes, coil springs, or control arm bushings, especially if the vehicle has been driven frequently in recent years. In terms of broader checks, given the vehicle’s age and moderate mileage, the buyer should inspect the tyres for signs of sidewall cracking or perishing, which can occur even at lower mileages due to prolonged exposure to UV light and temperature fluctuations. Check the 12V battery for signs of corrosion on terminals or a sluggish cranking performance, as older vehicles are more susceptible to battery failure from standing. Fluid levels should be checked, particularly the brake fluid, coolant, and engine oil, as these fluids degrade over time even when not in use. The service history should be reviewed to confirm that the 40 TDI’s turbocharger oil consumption has been managed, and that the engine’s service intervals for oil changes and filter replacements have been adhered to. Finally, a visual inspection of the exhaust system for leaks or excessive rust is advisable, as the A6’s body structure may be susceptible to corrosion in areas prone to moisture exposure.
