Hello, Ali!
Tell me, please. After reprogramming the first problem is disappeared or not?
UCE50AM04 is the latest firmware for this engine. But also service center has to modify some wirings of knock sensors. Was it done by service center or not? Ask them. I suppose that it hadn't been done.
On video all knocks are similar by time, sound and quantity.
By the way, try to check fuel line between High Pressure Pump and Fuel Filter for air. For doing this you have to buy transparent fuel tube. Like that =>

It is no good if you'll find a lot air inside tube while engine is running.
