BMW N57 3.0D 258PS POWER REDUCTION BY EGT - Najemnik95 - 03-18-2026

HELLO
CAN ANYONE EXPLAIN TO ME HOW TO ACHIEVE MORE POWER WHEN THE EGT IS LOW AND THEN THE POWER DROP DOWN TO NOT EXCEED A CERTAIN EGT VALUE?

Good news for you—the Bosch developer has already taken care of all that.

Well, it's not just to protect the DPF. It's also to protect the turbocharger, among other things.
