Frequently asked questions
Which Audi A5 engine is the most reliable?
3.0 TDI V6 (CCWA / CDUC) — Maint. Sensitive verdict. The 3.0 TDI V6 makes the A5 effortless and rapid — a smooth, strong and generally robust quattro diesel, the same well-regarded six used across the A4/A6/Q5. Watch the items typical of this V6: high-mileage timing-chain attention (rear-mounted chains), the intake/swirl and EGR system, DPF on short trips, and occasional turbo/injection. Thirstier and pricier to service than the 2.0, but a documented 3.0 TDI is a refined, durable grand-tourer engine.
