This BMW with a 2.0-litre diesel engine received a broader service and power calibration. The intake manifold was removed, the DPF was taken out, and changes were made to EGR control. Before programming, the car was measured on a dynamometer; the result was approximately 163 hp and 365 Nm.

After the ECU software was changed, the dyno recorded higher power and torque. The video title lists 202 hp and 447 Nm, but different final figures are also mentioned in the narration, so the exact result should be checked against the dyno printout.

Exhaust smoke was checked several times after programming. No visible smoke can be seen during the tests shown in the video. The device readings are displayed, but the unit is not clearly specified, so the figures are not interpreted here.
