The single-turbo Mercedes-Benz G 350 CDI was tested on a four-wheel-drive dyno. The initial run recorded approximately 208 hp and 520 Nm. Emissions-system changes had already been made to the vehicle: the catalytic converter had been removed, while the DPF remained in place.

After the initial software changes, the owner reported that fuel consumption had fallen from around 15 to 9.5–10 L/100 km. This is the owner’s observation, not a controlled fuel-consumption test. A power calibration was then carried out, and the dyno recorded approximately 226–227 hp and 586–587 Nm.

Blue-white smoke appeared during the power test. The technician in the video associated it with an injector that appeared to be nearing the end of its service life and leaking slightly. No injector repair is confirmed as part of this work, so the issue should not be treated as resolved.
