So I have the same issue though my vehicle has never stalled. Just unstable idle. Problem seems to be worse when it’s cold out. Think a lot of it has to do with the colder plugs with less gap. Mine are the same plug but set to .022 gap. I have also heard the throttle actuators being worn can cause this issue. The throttle blades are plastic from what I’ve seen so accelerated wear is possible. With the valvetronic system these cars have I wouldn’t think it would depend on the throttle actuators at idle that much but who knows. The other thing is if you have a cold start delete on top of everything else it may just be too much to have a steady idle when dead cold. If you have BM3 there is a cold idle setting I believe. May be worth a shot. It’s in the map configuration tab I think.
Good luck
