X3 F25 N55 [Stalling on Cold Start] [Live Data/Video/ISTA+]

Hello everyone! Video below with 3 view angles at the same time. I cant figure it out can someone point me in the right direction? Is this a O2 sensor pre cat? Open Loop on the O2 sensor is fine, and idles down correctly as well.

Symtoms
Stalling on Cold Start
Rough Idle - Low Speed/Idle
Lurching and loss of power
All gears affected at low speeds, N, P , R, D

Collected Diagnostics



Video
Almost completely stalls at 1:29 in the video.


Any help would be much much appreciated, thanks in advance!
