Audi A5 maintenance: the schedule, the costs, the traps
A compact luxury sportback with a gas powertrain. Below: the service intervals with real cost ranges, the repairs A5 owners actually report, and when a fleet operator would sell. Same data Carlyle uses to score fleet buys.

What A5 owners actually run into

Operator notes
All-new A5 (PPC platform) that replaces the A4 in the US for 2025; liftback/Sportback body marketed as sedan. 2.0T with timing CHAIN. Long-term reliability data still limited. 10k-mi synthetic oil.
When the smart money sells
On fleet math, a gas A5 retires around 95,000 miles - but the exit window opens earlier here: Dual-clutch (S tronic) / mechatronic risk window ($2,000-$3,600) opens ~90,000 mi. Carlyle's garage tracks this per car, against your actual odometer.
Cost ranges are typical US independent-shop estimates and vary by region and condition. Modeling, not mechanic advice - always confirm against your car's service records.
