Recurring P0100 Error and Reduced Acceleration in Opel Astra H 1.9 CDTI Post Flow Meter Replacement

Welcome to the car began to light the car indicator with the key and began to enter the emergency mode RPM up to 2000 thousand after connecting the computer shows error P0100 which indicates a problem with the flow meter. The indicator went out and lit up more than once, it was most lit on hot days, when it was cool the fault was gone.
The car went to the mechanic, his diagnosis also pointed to the flow meter. After replacing the flow meter, the indicator did not light up, but the acceleration of the car seemed to decrease slightly. Two weeks have passed and the problem has returned the indicator lights up and does not go out yet (heat returned he he) shows the same error as before. I will add that often at a turnover of around 2000 before repair and after a bit of a jerk. Maybe someone studied the subject Astra H and help?
Parameters view below.

Check the cables, the cube from the flow meter (cube near the computer) maybe something does not connect somewhere or is tarnished, frayed.
Since you replaced the flow meter and it was fine for a while, I would bet on cables.

What flow meter has been installed. Check the parameters before starting the car in the morning
engine (sensor temperatures should be similar). Provide more data
cars (preferably engine code). best regards

The car was again sent to the mechanic for complaints, again replacement of the flow meter and probably the throttle (cost PLN 300 again). I know from what the mechanic said, I'm sure about the flow meter because I took a photo. I picked up the car, there were no problems for two months and the error started to pop up again, I had enough, I promised myself that I would not visit this mechanic again. This time I went to another, diagnosed a computer defect in the throttle after dismantling, it turned out that it is heavily soiled with oil, showed me the pictures, so it was so far, no problem, no error pops up we will see after a long operation. I must add that I don't make Astra for many kilometers.

Today, more than a month passes, there are no mistakes, I don't get it, everything works, I'm happy with the last mechanic.
