I have a 2016 625i gator. The RPMs have began to go up and down at idle but are fine when operating. I have changed the oil and there is no gas in from short running and installed a new fuel filter. I pulled the plugs and they look fine.
Any ideas as to what would cause this?

Were there any symptoms prior to this, is the engine throwing any codes on the instrument panel, have you made any adjustments to the idle ?

It just started doing it. There don’t appear to be any codes
The instrument panel looks pretty sparse. I have not done anything to it.
