2007 Audi RS4 4.2L Petrol · V8 FYK

The most recent MOT inspection on 20 April 2026 resulted in a pass, though it carries an advisory regarding slight corrosion to the brake hose ferrules. When evaluating the broader maintenance trend, the vehicle shows signs of intermittent mechanical instability, particularly concerning the exhaust emissions and braking systems. The history reveals a significant failure in April 2025 due to excessive carbon monoxide levels and high idle speeds, alongside binding rear brakes. While the 2026 pass suggests these specific issues were addressed, the recurrence of emissions-related failures and the presence of new corrosion advisories indicate a vehicle that requires diligent oversight rather than one following a strictly preventative maintenance schedule. With a recorded mileage of 80,553 over 19 years, this Audi RS4 has averaged approximately 4,240 miles per year. This is exceptionally low usage for a high-performance vehicle of this age. While low mileage can suggest less mechanical wear on the engine and drivetrain, it also carries the risks associated with infrequent use. Vehicles that spend long periods stationary are prone to accelerated degradation of rubber components, fluid contamination, and uneven tyre wear. The history of binding brakes and suspension bush wear is consistent with a car that may sit for extended periods, allowing moisture to cause corrosion on brake discs and calipers or causing rubber bushings to perish from lack of regular movement and thermal cycling. During your test drive, you must pay close attention to the braking performance and the integrity of the suspension. Given the history of binding rear brakes and the recent advisory on brake hose corrosion, listen for any sticking or dragging sensations, or a smell of hot brake components after driving. Check for any pulsation through the brake pedal, which could indicate warped discs, or a pulling sensation to one side. The previous advisories regarding suspension arm ball joints and upper arm bushes suggest that the front end may exhibit clunking or knocking sounds when navigating uneven surfaces or during low-speed cornering. It is essential to verify that these components have been replaced and not merely monitored, as worn bushings will negatively impact the precise handling expected from an RS4. Furthermore, the history of excessive carbon monoxide emissions necessitates a thorough check of the engine's idling stability and exhaust note. Ensure the engine reaches operating temperature smoothly without erratic hunting or excessive smoke. Because of the low annual mileage, you should visually inspect the tyres for sidewall cracking or perishing, which occurs due to age rather than tread depth. Check the underside of the vehicle for signs of fluid weeping from seals that may have dried out, and confirm that the service history reflects calendar-based fluid changes for the coolant, brake fluid, and oil, as these degrade over time regardless of distance travelled. Finally, verify the condition of the battery and the charging system, as low-usage vehicles often suffer from electrical instability.
