Exhaust Flap Dummy Plug - BMW P/N 18302411427

I'm fairly certain they are all the same plug.
Haha did exactly that and sure enough, valve was open when car was off. Got that all sorted now, thanks my man!

On the dummy plug I looked up that part but one site said it’s not compatible with the X5 G05 even tho it looks identical. Any chance you know how I can find out? I saw in another post some suggested Alibaba but wanted to be sure before ordering. Great idea.

The other option is to use the ODB-II adapter and app to open the flap, then pull the fuse. There are several threads on this elsewhere in the forum.
I have a 2022 X5M50i with catless DP and i installed dahler exhaust flap module to keep the value permanently open .
