How many kilometers does the car have? There are many factors that can cause this to happen Try cleaning the EGR valve

I had something like that happen to me back in March 2020. On the shop, the mechanic tried to see if cleaning the EGR improved, to no avail. Ended up replacing the EGR with an aftermarket DENSO unit, and it solved the problem. That was over two years ago, since then no such problem occurred again.

And yes, I had the same issue, turned off the car, it disappeared and the car functioned normally.

In my case, replacing the EGR solved the problem.
