This 2014 BMW X5 F15 with a 3.0-litre diesel engine and EDC17C57 ECU was tested on a dyno. The quoted rating is 190 kW, or about 256 hp, and 560 Nm. However, the initial run on the factory software produced 221 hp and 470 Nm. Results were similar in fourth and fifth gear.

Calibration and follow-up diagnostics

After calibration, the dyno produced approximately 271–275 hp and around 600 Nm. Data logging was used to check turbocharger operation, fuel delivery and temperatures; no major deviations were identified in those parameters. The initial power and torque readings were still below the quoted ratings.

The video recommends a further check of DPF back pressure. A filter fault or blockage was not confirmed, so that check remained a follow-up diagnostic step.
