2.9L TFSI V6 - Twin-turbocharged performance version
Petrol
While accelerating steadily in Dynamic mode, listen closely for any hesitation or surging, as the B9's 2.9L twin-turbo setup can sometimes experience wastegate rattling or boost control solenoid sensitivities as they mature.
Check the ZF 8-speed automatic by coming to a complete stop and accelerating gently; ensure there is no 'clunk' or delayed engagement when shifting between Park, Reverse, and Drive.
Before starting the engine, physically inspect the radiator area for any signs of pink residue, as the cooling system's thermostat housing and water pump are components that may benefit from preventative monitoring in high-mileage units.
When maneuvering at low speeds with full steering lock, listen for any clicking or binding sounds from the front suspension, as the complex multi-link setup can occasionally show wear in the control arm bushings over time.
Time to consider a transmission fluid and filter flush to keep that ZF gearbox shifting precisely.
Consider having the spark plugs and ignition coils inspected or replaced to maintain optimal combustion efficiency.
A common point to review the suspension components and potentially the PCV valve assembly for signs of oil consumption or vacuum leaks.
Ensure the service history shows regular oil changes every 10,000km or 12 months using high-quality synthetic oil.
Verify that the brake rotors and pads have plenty of meat left, as the RS performance setup is quite substantial to replace.
Keep an eye on the Quattro system; ensure the differential fluids have been serviced according to the recommended schedule.
Check that all MMI software updates have been applied to ensure the infotainment and digital dash remain glitch-free.
Inspect the tire tread wear patterns to ensure the alignment is true, as the RS5's sporty geometry can be sensitive to uneven road surfaces.
Estimated repair costs if issues arise
These components are known to occasionally develop small leaks as the vehicle ages. It's wise to monitor coolant levels and budget for this as a preventative maintenance measure if you notice any sweet smells or residue near the front of the engine.
Given our lovely NZ chip-seal roads, the bushings in the multi-link suspension eventually soften. If you notice a slight looseness in the steering, you might eventually need to budget for a refresh of these arms.
Direct-injection engines can accumulate carbon deposits over many kilometres. While not always urgent, you might eventually need to budget for an intake walnut-blasting service to ensure the engine breathes perfectly.
