misfire issue

Selamün aleyküm friends, I have a pejo partner tepee zenith 2018 model 6 speed 120 HP vehicle. Vibration at take-off, knocking at gear changes, and the vehicle wobbles twice between 1000-2000 rpm when it is exactly 1800. Thanks in advance

Hello, my teacher. welcome aboard. Bluehdi engine I think. First of all, what is the mileage of your vehicle, sir? There are probably a few options, sir. air flowmeter - fuel quality - diesel filter - injectors - vibration at start-up may also be caused by the pressure pad. Don't forget to check the axle. and if there is a special service with the original software of the vehicle, have the injector check. I hope you don't have an edlue problem.

I am welcome, thank you, the previous owner of the edblue vehicle canceled the vehicle at 74 thousand. In the low speed feature, when the rpm is 1800, the vehicle will hold and release once. We changed the air flow meter. Fuel filter changed 500 miles ago. I don't think it will be from the pressure pad, but I still don't know.
