Which is more reliable TDI or TSI?
For instance, TDI engines are reliable and fuel efficient over long distances, but their fuel economy tanks around town and they have DPF filters that can clog – TSI engines are less fuel efficient, and less reliable overall, but they don’t have any DPF issues. TFSI engines feel smoother and quieter. TDI engines pull harder at low speeds and use less fuel on long runs.For instance, TDI engines are reliable and fuel efficient over long distances, but their fuel economy tanks around town and they have DPF filters that can clog – TSI engines are less fuel efficient, and less reliable overall, but they don’t have any DPF issues.tdi engines boast many of the same benefits as the tfsi engines, such as: superior torque and efficiency – tdi engines generate high torque and low revs, making them fantastic for long trips. Greater fuel efficiency – helping to contribute to longer driving ranges. Renowned for their robustness and longevity.
