While accelerating steadily in 'Dynamic' mode, check for any hesitation or surging which might suggest the twin-turbo system's vacuum lines or diverter valves are becoming aged and brittle.
Check this by navigating to a quiet street and cycling through the air suspension height settings; ensure the car levels promptly without any audible 'hissing' from the compressor or corner sag.
While driving at low speeds over bumps, listen carefully for any clunks from the front end, as the D4's sophisticated control arm bushings can show signs of wear once they have seen a few New Zealand summers.
Ensure the MMI infotainment screen retracts and deploys smoothly several times; stuttering or clicking sounds may indicate the gear mechanism for the folding screen is ready for a service.
Consider a full transmission fluid and filter flush to keep that 8-speed Tiptronic shifting as smoothly as the day it left the factory.
The engine mounts, often vacuum-controlled, may begin to lose their dampening efficiency; keep an ear out for extra vibration at idle.
A sensible time to inspect the cooling system components, specifically the plastic coolant flanges and water pump, to ensure longevity for your long-distance touring.
Prioritize high-quality synthetic oil changes every 10,000km; these V8s love clean, fresh lubrication to keep the turbochargers happy.
Check the condition of the cabin air filter regularly to ensure the sophisticated climate control system isn't working harder than it needs to.
Verify that the battery is healthy and registered to the vehicle's gateway, as these complex electronics are very sensitive to voltage fluctuations.
Inspect the brake pads and rotors during every service, noting that the 'Sport' variant often utilizes high-performance materials that provide excellent stopping power but wear progressively.
Ensure the panoramic sunroof drains are kept clear of debris, particularly if the car is parked outdoors, to keep the interior upholstery pristine.
Estimated repair costs if issues arise
In cars of this age, it is a prudent piece of Future Budget Planning to have the turbo oil intake screens inspected. If this component needs attention in the future, the estimated cost in NZ covers the specialized labour required to access these components deep within the V8 engine valley.
The air suspension provides that iconic 'magic carpet' ride. Depending on the car's history, you might eventually need to budget for a compressor rebuild or a strut replacement if the seals begin to age.
To maintain that precise Audi steering feel, the control arm bushings may eventually require refreshing. It is common to consider replacing these as a full set to ensure balanced handling.
