Random needle sweep

Hello folks !
I had my OBDElven Pro since over a year, and today I decided to activate needles sweep on my cluster.
I think it's a good and nice option to activate, making your car more "modern".
However, I have an issue because it's happen randomly.
Sommetimes needles will sweep, and sometimes not.
Any idea about the issue it could be ?

Had similar when I enabled mine with OBDEleven.
Turns out it won't do it all the time if you flip the key in quick succession.
But it does it on mine consistently if the car's been off for some certain amount of time.

This function is included in the factory programming for my old 2011 Audi S4, but, in normal use or starting of that car, it never "happens" as these cars have a "push key" ie just press and release the key with the clutch pedal fully down and the engine starts up.
Now, if I don't press down fully on the clutch, the engine will not get started and so the ignition "switch on" just goes through its normal routine, but as it completes that routine without starting the engine, needle sweep will occur as the starting routine was run for longer - maybe. So, for that car of mine, why did they bother including needle sweep - I can't say.

Hmmmmmm interesting.
I will try later by pushing the clutch (it's a manual) first, and after, turn the key.

I'd think that if you
don't press the clutch pedal down when trying to start the car, it will not start - but needle sweep should "happen".

So here what I've tried.
I unlock the car, leaving home works perfect.
Sit in the car (leaving home stop working), I turned the key (clutch not pressed) and needles sweep happen.
I remove the key, try again, sweep again and again.
I tried more faster (with the leaving home working), nothing happen.
I desactivated coming/leaving home: change nothing, needle sweep was not working.
So, it's strange.
