Top Risk Areas
The systems that tend to fail first on the 2017 Audi S4, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
Failures of the water pump, thermostat, and PCV (Positive Crankcase Ventilation) valve are common, leading to coolant leaks, overheating, or oil consumption. These plastic components can degrade over time.
The sophisticated 7-speed dual-clutch transmission can develop issues with its Mechatronics unit, leading to rough shifts, hesitation, or complete failure. Clutch packs can also wear out, especially under aggressive driving.
As a direct-injected engine, carbon deposits can accumulate on intake valves, reducing engine efficiency and potentially causing misfires or rough idling. While less severe than naturally aspirated FSI engines, it's still a factor.
2017 Audi S4 Mileage Danger Zones
The mileage windows when the 2017 Audi S4 most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Low Risk Zone
At this mileage, the car is still relatively new. Focus on routine maintenance like oil changes and tire rotations. Early PCV valve failures are rare but can occur.
Maintenance Zone
This mileage often coincides with major service intervals, including spark plugs and possibly the S-tronic fluid/filter change. Be alert for the first signs of water pump or thermostat leaks.
Elevated Risk Zone
The risk of higher-cost repairs increases here. S-tronic Mechatronics or clutch pack wear can begin to manifest. Control arm bushings are likely due for replacement, and carbon cleaning might be considered.
High Risk Zone
Beyond 120,000 miles, the S4 enters a phase where nearly any major component could fail. Preventative maintenance is key, but budget for the possibility of expensive engine, transmission, or supercharger-related repairs.
2017 Audi S4 Ownership Cost Outlook
What it typically costs to keep the 2017 Audi S4 on the road. Full 5-year cost-of-ownership projection and major-failure-risk forecast are in the report.

Moderate Repairs
$1,000-3,000 occasionally (e.g., water pump, PCV, control arms)
How Long Does the 2017 Audi S4 Last?
While the 2017 S4's 3.0T engine is capable of very high mileage, prioritize models with comprehensive service records. Expect to address cooling system components and potentially S-tronic service around the 60,000 to 90,000-mile mark, regardless of prior care.
