2021 Audi RS 4 Carbon Black Tfsi Quat A 2.9L Petrol · KB16 FEB

The most recent DVSA MOT test for this 2021 Audi RS 4 Carbon Black TFSI Quattro A was conducted on 16 January 2026, resulting in a clean pass with no defects or advisories recorded. The previous test on 2 January 2025 also returned a pass with no recorded issues, indicating a consistent pattern of roadworthy compliance across consecutive annual examinations. With no advisories logged on either occasion, there are no immediate maintenance flags emanating from the official test history, suggesting that the wear-related items typically scrutinised under MOT legislation have remained within legal thresholds at the most recent inspection. The recorded mileage of 7,873 miles against a vehicle age of approximately five years equates to an annual usage rate of around 1,575 miles, which is exceptionally low even by typical low-mileage standards. This pattern suggests either limited use as a secondary or leisure vehicle, prolonged periods of standing, or a combination of both. While low mileage reduces wear on high-cycle components such as the clutch, drivetrain, and brake friction material, it introduces its own set of mechanical concerns relating to calendar-based degradation and standing-related corrosion. The absence of any mileage progression data between the two recorded MOTs is itself a point worth clarifying with the vendor, as it may indicate gaps in use or recording. Given the low annual mileage and clean test history, particular physical attention should be directed towards components that suffer from age-related deterioration rather than use-related wear. Tyre sidewalls should be examined closely for perishing or cracking, as tyres older than five years begin to degrade structurally even if the tread depth remains adequate, and the date code on the sidewall should be checked to confirm the rubber is not beyond a safe service life. Brake discs and calipers are prone to corrosion from prolonged standing, so the buyer should inspect for surface oxidation on the discs, seizeage of the caliper pistons, and uneven pad imprinting. The 12V battery is another common casualty of low usage; a voltage and load test is prudent, and the auxiliary battery used for stop-start and ancillary systems should likewise be assessed. The underbody, exhaust mounting rubbers, and suspension components should be examined for dry rot and corrosion consistent with limited road exposure. Fluid degradation should also be considered carefully, as oils and coolants degrade with time irrespective of mileage. Engine oil, transmission fluid, differential fluid, and the haldex coupling oil in the quattro system all have finite service lives, and a comprehensive service history with documented dates rather than purely distance-based intervals will be essential to confirm the mechanical integrity of this vehicle. On a test drive, the buyer should listen for any suspension clunks over uneven surfaces that might indicate perished bushes or seized components from inactivity, monitor for brake shudder or pulling that could suggest corroded or binding calipers, and observe any irregular idle or warning lights that could indicate sensor or battery issues arising from infrequent use. Verification of the service book stamps, particularly for the timing chain interval and turbocharger-related maintenance relevant to the TFSI unit, will be critical in establishing whether this low-mileage example has been correctly preserved or merely left to stand.
