My 2018 GTS is doing this. My wife hates driving this. In carpool lane, when going slow, the car stumbles. I already had a new transfer case installed.

@Cnair Did you ever find a solution?

I had the EVOMS DVs installed plus have an EVOMS tune....she is not noticing it now. Vehicle has 46k miles and stock DVs may have been on their way out with the tune. Not sure if that was the issue but she is not noticing it any more

This might be a silly question - but have you guys changed the spark plugs?

I have tried new plugs and new diverter valves. I also installed new air/oil separators.
Also change both pressure sensors and the crank sensor.
No change...
