Common Issues to Watch For

Based on the 2017 AUDI S3's fuel type, age, and engine size, these are the most likely problem areas to check.

Timing Chain / Belt

At 9 years old, check whether the timing belt has been replaced (typically due every 5-7 years or 60,000-100,000 miles). A snapped belt can destroy the engine.

Suspension Wear

Always request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
