the egr sensor is terrible crap. inside there is something similar to a silicone jelly with wires embedded in it. There is suction on the sensor from both sides, so nothing should get there. the reading from this sensor also flies like a dick in the pants. at constant revolutions it should have some relatively constant values. unfortunately this is not like that. Despite the sensor being several months old, I sometimes feel the tugging again.

in my case problem was with DPFE sensor. hard shifting  and jerking at about 2000 RPM at constant speed.

sensor : 2261799 ,KA1A-5L200-AB , KA1Z-5L200-A

Disconnect the EGR and drive one day. I'm not saying the EGR  is broken. My car stops jerking. I plan to disable the EGR  programmatically. EDGE 2019 ...
