Actually i've found out the fault.
It is related to a certain values i use in Automation like suspension and a certain engines positioning or size or setup maybe or the way the body parts are placed like wheels and tires size causes BeamNG to read it faulty causing strange faults like random impect detection (when using advanced trim menu)
i got rid of the engine issue but currently only the G-Gauge skyrocking for no appearent reason.

I've never encountered that in testing long ago on an export to Beam, that's a very interesting issue, nothing I can actually do to solve it however as I only really know Automation side of modding, it may be worth inquiring on the Official Automation Discord server?

There is a strange problem with this mod ( maybe BeamNG issue )
For no apparent reason the engine might get damaged, the car receives random unknown impact detection on a certain body parts, the engine randomly gets oil starvation, i also noticed the G-Force gauge sky rocketing on forward & backward repeatedly ... is it possible to fix it ?
