308 1.6 Bluehdi gets jerky during start

2016 model 1.6 bluehdi eat6 My car has been making a jolt while cranking lately, it's not clear when it's cold or hot, but it usually does it in hot weather, it works like an advance or backfires. However, it can happen again.

I have the exact same problem in my 2018 1.6bluehdi vehicle, there may be something about the engine ear, I will have it checked out sometime.

It's a good idea to have the engine mounts checked.

Engine mount, transmission mount, flywheel (if there is a sound), starter motor, if they are still intact, injector

The engine gearbox middle block is solid, but the crank is running, the last possibility is the injectors.

The master at the Peugeot service says it may be the rail switch, he says, this sensor either completely breaks down - if the socket - cable breaks, it gives a fault code, or leaves it on the road, or stays at a value and stays at a certain value without causing the vehicle to malfunction, reading the pressure incorrectly and giving wrong values to the ecu and such a jolt during the start. He said maybe it burns the fuel a little too much, he also said that there may be a pressure error on the pump, it may be from the pressure sensor, but most likely it is in the injectors that the rail switch should be changed first, but there should be vibration and sound fluctuation when the relay is working normally. Ben rail. I'm going to order and replace the sender, there is no Peugeot at the moment, I will write again when I change it
