Hello, I am the owner of an 03 530i and the ultrasonic sensor module that goes on the headliner of the car has been broken from some time(the mount I mean) it seems to have failed how every single other post mentions it to fail, the 2 clips that drop down to latch just break off, I have been looking and it seems that this part no longer exists anymore, literally no one has it, I’ve been trying to use some double sided tape but it’s been failing because of the cold(Colorado). Would anyone know any better way to mount it(sorry no pic). Or on the off-chance some one has the dimensions or a CAD file I could design/3d print.

Thanks
