What is the difference between the M54B25 and other M54 engines?

The M54B25 makes 141 kW (192 HP) and 245 Nm. The other M54 engines are: M54B30 with 170 kW (231 HP) and 300 Nm (2000 to 2006).

Engines in one family share a basic block, but the turbo, the injection, the sensors and the engine computer can differ. A higher power version often has different pistons, a bigger turbo or a different fuel system.

This is why we ask for the exact code. Fitting a different version can work, but the wiring, the software and sometimes the gearbox must be changed to match.
