Gently accelerate and decelerate to listen for any surging or hesitation, as the ZF 8-speed transmission should shift imperceptibly. Jerky shifts can sometimes indicate the mechatronics unit or fluid service requirements.
Turn the steering wheel to full lock in both directions while at a slow crawl to listen for any clicking or binding from the Quattro drivetrain or CV joints.
Before starting the engine, check the MMI screen for any active warning lights and ensure the electronic parking brake engages and disengages without delay or grinding noises.
During the test drive, monitor the coolant temperature needle to ensure it sits consistently at the midpoint, as B9 cooling systems perform best when fully healthy and free of thermostat housing seepage.
Usually marks the interval for the first transmission fluid and filter flush, which helps maintain the ZF gearbox's longevity.
A common window to inspect the control arm bushings and engine mounts, which can start to show wear depending on local road conditions.
The typical recommendation for checking the water pump and thermostat housing for signs of weeping, as well as replacing spark plugs to maintain optimal turbo performance.
Verify the service history confirms regular oil changes every 10,000km or 12 months using VW/Audi 504.00/507.00 spec oil.
Check for a consistent record of brake fluid flushes, as these are critical for the safety of a high-performance Quattro vehicle.
Inspect the Quattro system fluid levels during a professional pre-purchase inspection to ensure the differential is operating quietly.
Review the dashboard for any pending software updates via the Audi MMI, as these can resolve minor electronic niggles.
Look for receipts confirming the use of high-quality tyres, as the S5's geometry is sensitive and performs best with premium rubber.

These components are known to occasionally develop small leaks as the car ages. It is a common maintenance item that ensures the 3.0L V6 stays perfectly chilled during spirited drives.
If you notice a slight dull knock over bumps, you might eventually need to budget for refreshing the suspension bushings to restore that 'factory fresh' handling feel.
While the ZF 8-speed is world-class, fluid and filter service is a wise investment to keep shifts crisp. Depending on your driving style, you might eventually need to budget for this service to protect your gearbox internals.
