Hi y5choi,
I will keep you posted when this door acts up but I hardly use that door.
It will probably go way when it gets warmer. If its broken I ll just have to bring it to the dealer (warranty)

In regards to adaptive, one cold morning when i started the X5 it gave me a
!!warning!! that ! ADPT Head malfunctioned ! and to !! bring to service !!.
Still drove off with it anys cus I had to go. When I got to my destination, I turn off the the X5 and turned it on again to see if the warning was still there and it went away.
I figure it probably warmed up the assembly and was fine till then.
