Audi 2.0 TDI vs BMW B47: Which Diesel Should You Trust?

Audi 2.0 TDI: what matters

Audi 2.0 TDI cars can be efficient and durable, but the surrounding systems matter. DSG or S tronic history, DPF/EGR/NOx health, injector data, and cooling behavior should all be checked.

If quattro is fitted, confirm what system it uses and whether the relevant driveline service has been done.

BMW B47: what matters

The B47 is usually a stronger modern BMW diesel choice than the older N47, but it still needs evidence. Look for EGR campaign history, DPF loading, coolant stability, oil service proof, and clean boost delivery.

The decision

Choose the Audi when gearbox history and emissions data are stronger. Choose the BMW when EGR/DPF data is clean and the car’s overall condition is better. Walk away from either one if the seller refuses a scan.
