The video tests a DPF refurbished in Lithuania that does not contain a catalytic converter. After installation, the workshop meter showed readings of approximately 47,000, 50,000 and 48,000. The video does not state the measurement units or full test conditions.

What does this test show?

The technician compares the readings with a threshold of 1,000,000 mentioned in the video. Since the units and vehicle details are not given and no official CSDD inspection result is shown, these figures should not be treated as a universal inspection criterion or proof that the vehicle passed. A particle reading also does not confirm that the catalytic converter is working.

A filter test does not fix an engine problem

The video mentions a vehicle with an engine problem and oil consumption. Fitting a DPF does not by itself fix that cause or guarantee the filter’s long-term operation. In this case, fitting the filter is discussed as a temporary option that could later be removed; no repair or long-term result is shown.

The DPF and catalytic converter are separate systems

The tested filter does not contain a catalytic converter, and the video also mentions a strong exhaust smell. A low particle reading alone does not show that the complete exhaust after-treatment system is present and working correctly. A permanent repair requires restoring the exhaust configuration intended for the vehicle and addressing the engine problem.
