Two things come to mind. One is the possiblity that you are pulling in air into the view, the second is a faulty PD injector cable harness which is inside the head. Does it shack at tick over. If it is the harness then the missing will be very regular in the exhaust note. There also may be an error code stored. Regards Peter

thanks. it doesn't shows any error codes. it feels like some part stops working because engine works differently when it shakes

Can you hear it in the exhaust note and is it regular. Does it do it at tick over. Please try and answer the questions put to you. If some one has done a code read did they check the temp sensor values, there is one for the gauge and one for the ECU. Regards Peter

Does it shake when you take your foot off the throttle. Regards Peter

It does it even with your foot off. Diesels shut fuel off completely with the throttle off so either you have a leaking injector which woulf show up at tickover, or you have a dual mass flyweel problem that when warm/hot the centre is moving and unbalancing the flywheel. This will cause a very regular vibration which of course would be speed and revs dependant. Regards Peter
