4.2L FSI - S5 Performance trim
Petrol
While idling in Park, listen closely for a light ticking sound near the engine bay; this could be related to the carbon buildup on intake valves, which is common in high-performance FSI engines of this era.
Check this by shifting between Drive and Reverse; ensure the transmission engagement is smooth, as the S-tronic dual-clutch units in the B8 platform may show hesitance or shuddering if the mechatronic unit is nearing the end of its service life.
While on a straight piece of road, feel for any shimmy or vibration in the steering wheel; the suspension control arm bushings in these vehicles can wear over time, often resulting in minor handling feedback issues.
Before turning off the engine, operate the MMI system and test every button; these early infotainment units can occasionally develop minor electronic gremlins that are best identified before you commit to the purchase.
Usually marks the period where cooling system components like the water pump and thermostat may show signs of natural fatigue.
Often the time to verify if the dual-clutch transmission service has been completed, which is vital for smooth operation.
Generally the interval where suspension components like shock absorbers or control arm bushings might require a refresh for optimal handling.
Ensure you have a complete record of oil changes, as these engines are quite particular about high-quality synthetic lubricants.
Check for any signs of dampness under the floor mats, as the sunroof drains in this generation can occasionally become blocked.
Confirm that the brake pads and rotors have been inspected recently, as the S5 performance braking system is effective but will wear with spirited driving.
Verify the status of the coolant hoses, as the rubber can become brittle over the years in our New Zealand climate.
Make sure the battery is in healthy condition, as these cars are quite sensitive to voltage drops and electronic stability.
Estimated repair costs if issues arise
Because of the direct injection system, carbon deposits can build up on the valves over time, which may eventually affect engine breathing. It is worth planning for a walnut-blasting service down the line to restore peak performance.
The dual-clutch transmission is a highlight of the driving experience, but if shifting quality changes in the future, you may need to budget for a mechatronic unit service or replacement to keep the gear changes crisp.
Depending on the car's history, you might eventually need to budget for replacing the control arms or bushings, which helps maintain that signature Audi 'planted' feel on the road.
