Vibration 320d Automatic at idle (Torque converter?)

Hi,

since a week I have the next problem with my 2013 320d 8-automatic (GA8HP45Z).

There is a vibration when the car is stationary, gear in D (Drive) and foot on the brakes (e.g. waiting at a trafic light)
It goes away when I put gear in N (Neutral) or P (Park).
Vibration seems a little bit less when I manual shift to gear 3.

Before the vibration started, there was allready not a smooth stop. Also there was more torque on the drive when stopped at traffic light. Like if NIC (Neutral Idle Control) and SST (Soft Stop) didn't work. I checked with Esys, and NIC seems Aktic in EGS module.
When put in Park, there is a thump. It sure is not smooth.

- Could this be a bad working torque converter?
- I have read something about converter clutch lockup. Is this something that can cause this?
- Car is remapped by previous owner (163hp to 230hp). Could it be it changed something in transmission as some prefer "the car be to ready for a sprint, without delay of NIC".
- When stationary in D, foot on brake. Is it possible the driveshaft is vibrating?

Hope to get more info from you guys!
tank you
