Hello, my car is 2.0hdi 406. When I press the gas, I hear a sound coming from under the hood as in the video (it never makes it while idling). It does not happen all the time. It does it sometimes. When I do this, I have a misfiring problem in the car. I took it to the mechanic, but there was no sound when I took it to him. The man could not find the problem. If anyone has experienced this or has an idea, I would appreciate it if you could help. https://youtube.com/shorts/2jjpH32t4Io?si=Wf0ZqfX01Gtf7SeC
