Petrol
During low-speed maneuvering, listen for any light clicking or knocking from the front suspension, as the complex multi-link setup can experience wear on control arm bushings in higher-mileage examples.
Check the responsiveness of the ZF 8-speed gearbox by switching between Comfort and Dynamic modes; ensure the shifts are crisp and free from hesitation or erratic flaring.
While driving, keep an eye on the coolant temperature gauge and listen for the electric fans; ensure the system stays stable, as the cooling system components are known to be sensitive in these high-output V6 configurations.
Inspect the infotainment screen and digital cockpit for any flickering or software glitches, as the MMI systems can occasionally experience connectivity hiccups that require a reset or software update.
Consider a full transmission fluid service and inspection of the secondary water pump.
Recommended timeframe for spark plug replacement and a detailed inspection of the turbocharger vacuum lines.
Typically the time to assess suspension dampers and check for any minor cooling system weepage around the thermostat housing.
Verify the service history confirms regular oil changes every 10,000km or 12 months using high-quality synthetic oil.
Check that the Quattro system fluid has been serviced according to the recommended schedule to maintain driveline health.
Inspect the tyres for uneven wear patterns, which can indicate if the wheel alignment needs a professional adjustment.
Confirm the brake pads and rotors have adequate life remaining, especially considering the performance nature of the RS4.
Ensure all recall campaigns regarding the software or auxiliary components have been completed by an authorised Audi service centre.
Estimated repair costs if issues arise
Future Budget Planning: These engines run quite hot; if you notice minor coolant weeping in the future, it is often a sign to replace the thermostat housing or associated seals to maintain optimal operating temperatures.
Future Budget Planning: Depending on the car's driving history, you might eventually need to budget for performance-rated discs and pads, which are a significant component of the RS4's running costs.
Future Budget Planning: If the steering feel begins to lose its sharpness over time, it is common to consider refreshing the front control arm bushings to restore the handling precision the RS4 is known for.
