That warning comes on because you need a DFP service which cleans the filter. This is a Euro car so we don't have any pictures/information so you will need to have the service done and the light reset. Please let us know what happens.

I tried to drive fast and keep engine higher 2,000 rpm. Today, I started engine and drove about 5 km, the alarm was disappeared.
Hope it will be okay, but maybe need to check the sensor.

That can help keep the DFP filter clean but there is a procedure which does a better job. This video can help:
