This BMW E61 has a 2.5-litre diesel engine and an EDC16C31 control unit. It arrived after software work at another workshop because the DPF warning continued to appear. The previous file and its settings were reviewed.

The car had already been tuned. A dyno run with the previous file recorded 208 hp and 497 Nm. After reviewing and correcting the ECU calibration, a new file was prepared. The car has an automatic transmission, and the power test was performed in fifth gear.

After the correction, the dyno recorded about 226 hp and 504 Nm. This is a comparison with the previous modified calibration, not with the factory setup. The video refers to the car as a 2003 or 2004 model, so the exact year is not specified.
