Only happens on deceleration between about 90km/h and 120km/h. It seems to be more pronounced in 6th gear, although you can feel it very slightly in 5th.
Goes away as soon as you push on the accelerator in the slightest, and at lower then 90km/h and at any speeds including... much higher then 120km/h it's smooth as butter.
I've told the dealer about it but haven't got around to bringing it in yet due to being super busy at work. But I'm gonna get some time where I can actually take it in on a week day. When I do, It'd be nice to be armed with whatever info that may be out there.
Thanks!

Had a very similar thing. It was the runflat goodyears. They flatspot overnight. In the morning going to work I felt it more than coming back in the afternoon.
Try using 30psi. After 15k miles it kinda smoothed out. But it drove me crazy.
You feel it more in the back because the rear is lighter.
Also under full acceleration sometimes the driveline vibrates or feels like it does.
I blame the rubber discs that are used in the driveshaft. Its the nature of those things. If you shock them (like the A10 does) they sometimes deform and vibrate until you release the load and they come back to the center.
