Petronas 95 causing jerk on low rpm when deaccelerating in hybrid, it is Petronas or the eco mode.?
Running 97, also jerking. It's disengaging the transmission to charge dem batteries.
It jerked because you accelerated after it disengage the gear, then it needs to re-engage again since you asked it to accelerate.
If you then let go the throttle because of the jerk, you will cause driver induced throttle oscillation which will jerk again due to deceleration -> disengage.
At least I think that is what is happening.
Just mentioned about this yesterday over
here. Follow through the links; linked in that post for more info.

Also, one difference compare to before is that while the clutch is engaged to the engine during acceleration and high-speed cruising, it’s disengaged from it during startup and low- to medium-speed cruising to reduce losses. The transmission is also disconnected from the engine during deceleration, and this improves energy regeneration.

Image: Point #3This should happen more frequently when you are out of batteries (2 bar -> engine forced on to charge batteries) and at low speed/traffic jam crawl. Worse if on incline and worse if your driving style is to step the paddle lightly.
If it just jerked once, then that's not the case I described above. That's just disengaging the clutch/transmission like manual car. (probably)
