4.2L FSI V8 - High-revving naturally aspirated
Petrol
While accelerating in manual mode, feel for any hesitation or 'hunting' in the S-tronic gearbox; erratic shifts could suggest that the Mechatronic unit or dual-clutch packs might require attention.
With the engine at operating temperature and idling, listen closely for a rhythmic ticking or rattling from the engine bay, as carbon buildup in the intake runners is a known characteristic of the 4.2L FSI engine.
Gently navigate over uneven surfaces and listen for clunks or knocks from the front suspension, which may indicate that the control arm bushings or dynamic steering rack components are nearing the end of their service life.
Inspect the MMI screen and electronics extensively; common age-related gremlins can sometimes arise from moisture in the boot-mounted control modules or aging battery health.
Time to evaluate the state of the suspension bushings and potential carbon cleaning services for the intake valves.
A significant point where the S-tronic dual-clutch fluid and filter service is essential to maintain smooth operation.
Consider having a specialist inspect the cooling system components, including the water pump and thermostat, as plastic components may show signs of age.
Prioritise high-quality synthetic oil changes every 7,500km to keep the high-revving V8 running at its best.
Keep a close eye on the coolant levels; these engines like to stay at the perfect operating temperature.
Ensure the S-tronic transmission oil change intervals are strictly adhered to, as this is the heart of the driving experience.
Periodically check the brake pad and disc wear, especially if you enjoy exploring the performance capabilities of the RS5.
Have a trusted specialist run a diagnostic scan occasionally to monitor for any 'soft' codes that might be hiding in the background.
Estimated repair costs if issues arise
Due to the direct injection design, carbon deposits can build up on the intake valves over time. If you notice a slight drop in power or uneven idle, you might eventually need to budget for a professional cleaning service to restore the V8's breathability.
The dual-clutch transmission is a marvel of engineering, but in cars of this age, it's common to consider the potential for future electronic control repairs. Setting aside a contingency fund will ensure you aren't caught off guard if the transmission requires a specialist calibration or repair.
The RS5 is a heavy, performance-oriented machine, and over NZ roads, the front suspension components work quite hard. If this component needs attention in the future, it is often wise to replace the bushings or arms as a complete set to maintain that sharp handling.
