Hi guys. Lately I have problems with the “minimum”. The car rpm-s go to low and sometimes the engine turns-off

. This especially happens when the engine is cold.
Now I know of the problems with starting the engine and rpm-s going low on all the fiesta range but I thought it was fixed with the last software.
They told me they uploaded the latest one, how can I check this?
I also have the problem, going down the hill for example, pushing the clutch down and the rpm pointer goes crazy up and down

.
Regards.
