Reliability, common problems and owner reviews for the Audi Q5 3.0 TDI V6 (CCWA / CDUC). Check this before you buy used.

The 3.0 TDI V6 makes the Q5 effortless — a smooth, strong and generally robust quattro diesel, the same well-regarded six used across the A4/A5/A6. Watch the items typical of this V6: high-mileage timing-chain attention (chains are at the back of the engine), 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 long-distance engine.
