Knock while cruising

Hello everyone, my 2008 model 1.4 HDI 207 makes a sudden knock while driving while driving and then continues on the road. When I connect it to the device, there is no fault code, and no fault lights on the information display. What could be caused by?

The weather meter may be troublesome. And when was the last time the fuel filter changed.

The reason has been found. Crank sensor is loose. The problem was solved by taking it out.

Thanks for the return.
