Short answer

Audi S4 coverage spans 2000-2025 with structured year, market, configuration, evidence-state, and inspection context. It is not a reliability score.

Key takeaways

  • Supported years: 2000-2025.
  • Structured variants: 87.
  • Tier: Tier B.
  • Recall applicability must be checked by VIN.
  • Complaint signals do not prove defects or frequency.

Audi S4 coverage at CarFaultIQ spans 2000-2025. This canonical model hub combines structured year and configuration data with cautious evidence context, inspection priorities, and diagnostic navigation; individual trims and model years remain selectable data, not separate pages.

Audi S4 coverage at a glance

  • Supported years: 2000-2025 across 24 documented model years.
  • Market scope: United States and Canada.
  • Structured depth: 24 canonical model-year records and 87 source-backed configuration variants.
  • Page tier: Tier B — structured factual coverage with explicit evidence limitations.

Powertrain, fuel, and drivetrain coverage

The structured snapshot records body styles as |Cabriolet, fuel types as Premium Gasoline, and electrification as Gasoline|Gasoline|Z. Drivetrain labels include 4WD|4WD/AWD|AWD; transmission labels include Automated Manual 7-speed|Automatic (AM-S7)|Manual 6-speed|Automated Manual 8-speed|Automatic (AM-S8)|Automatic (AM-S7)|Automatic 7-speed|Manual 6-speed|Automatic (AM-S7)|Manual 6-speed|Automatic (S5)|Manual 6-speed|Automatic (S6)|Automatic Select Shift 6-speed|Manual 6-speed|Automatic (S7)|Automatic Select Shift 7-speed|Manual 6-speed|Automatic (S8)|Automatic (S8)|Automatic Select Shift 8-speed|Automatic 5-speed|Manual 6-speed. Availability varies by year and market, so use the selected-year module rather than treating this list as one configuration.

Evidence state

This is a structured factual model hub. No local recall or complaint evidence is safely matched at model level for public claims, so this page does not infer common problems, reliability, best or worst years, absence of recalls, absence of complaints, failure rates, or repair costs.

What to inspect first

  1. Confirm the VIN, exact model year, market, trim, and drivetrain before applying any evidence or service information.
  2. Complete a cold start, warning-light bulb check, road test, brake check, tire inspection, fluid-leak inspection, and diagnostic-code scan.
  3. Check steering tracking, suspension noise, brake feel, cabin electronics, and evidence of unresolved fluid leaks.
  4. Confirm all four tires match in size and wear, then check AWD/4WD engagement and driveline noise without assuming every configuration uses that system.

Diagnostic paths

These references are relevant starting points, not claims that a condition is common on this model.

Source limits and review method

Vehicle identity, year, market, body, powertrain, and configuration fields come from the CarFaultIQ v3.1 structured dataset and its traceable source-evidence records (DOE/EPA FuelEconomy.gov|DOE/EPA FuelEconomy.gov|Natural Resources Canada). Recall and complaint data, where present, come from local NHTSA-derived snapshots. Recall applicability remains VIN-specific; aggregated complaint signals are owner reports and do not prove causation or population frequency.

Questions about Audi S4 coverage

Frequently asked questions

Does this page rank the best or worst Audi S4 years?

No. It reports structured coverage and evidence limits without rating reliability, safety, repair cost, or model years.

Does a recall match mean every Audi S4 is affected?

No. Applicability depends on the VIN, build information, equipment, market, and remedy status.

Are complaint signals confirmed defects?

No. They are aggregated owner-reported signals and do not prove causation or population frequency.

Start with the evidence you have

A symptom and an OBD code are separate evidence channels. Use either one; do not assume a stored code proves a particular repair.
